The contract between EPG Client and EPG Web allows TCP communication initiated by the client toward the webserver with TCP destination port 80. This means that the host in EPG Client can establish a connection to the webserver in EPG Web on TCP port 80. However, the contract does not allow the webserver to initiate a connection back to the host on the same port, which is typically used for HTTP traffic.

References: The explanation is based on the understanding of Cisco Application Centric Infrastructure (ACI) contracts, which are used to define the communication between EPGs (Endpoint Groups). For more detailed information, refer to the Cisco Data Center Core Technologies source book and the ACI documentation available on Cisco’s official website.

To meet the deployment requirements for implementing VSANs on a Cisco MDS 9000 Series Switch, the correct steps are to create VSAN 10 in the VSAN database and bind it to the interface fc1/1. This assigns the host on port fc1/1 to VSAN 10. Additionally, enabling VSAN trunking on the Inter-Switch Link (ISL) and allowing VSAN 10 on the ISL ensures that the port channel 10 can pass multiple VSANs, including VSAN 10. This configuration allows for the segregation of traffic and maintains the isolation of different VSANs while still permitting communication across the shared physical infrastructure12.

The VLANs capable of being assigned on vPC interfaces are those that are active on the vPC peer-link. According to the exhibit, the active VLANs on the vPC peer-link range from 100 to 105. However, VLAN 105 is not listed under the individual port statuses for Po7 and Po8, which indicates that VLAN 105 is not actively participating in the vPC. Therefore, the VLANs that can be assigned to vPC interfaces are 100-104.

References := For a detailed understanding of vPC configurations and VLAN assignments, one should refer to the Cisco Data Center Core Technologies study materials, which provide comprehensive coverage of vPC operations and best practices.

A strict CoPP (Control Plane Policing) policy is designed to manage the traffic flow of control plane packets to protect the control plane of routers and switches from being overwhelmed by unnecessary or malicious traffic. When a ping sweep, which involves sending ICMP echo requests to multiple hosts to identify live devices on a network, is performed on a network connected through a switch with a strict CoPP policy, excess ICMP packets can be dropped to prevent them from consuming excessive resources. References: Cisco Data Center Core Technologies source documents or study guide

The Peer Gateway feature on Cisco Nexus switches is designed to address the exact scenario described. When enabled, it allows the vPC peer switches to forward traffic based on the SVI MAC address, even if it is not the HSRP MAC address. This is particularly useful in cases where end devices do not use the HSRP virtual MAC address for the gateway and instead use the physical MAC address of one of the HSRP routers1. By using the Peer Gateway feature, both N9K_1 and N9K_2 will be able to forward traffic for VLAN 23, ensuring that the packets are not dropped due to the vPC loop prevention mechanism123.

References: = This information is supported by Cisco’s documentation on Nexus 5500 Platform Layer 3 and vPC Operations, which explains the use of the peer-gateway command to allow Layer 3 forwarding in scenarios where the destination MAC of the incoming packet is the MAC of its vPC peer switch1. Additionally, discussions in the Cisco Community confirm the necessity of this feature when certain devices on the network do not properly send traffic to the MAC address specified in the ARP234

To SPAN traffic in both directions from a vNIC on a VM deployed on a Cisco UCS blade server to a packet analyzer connected to UCS-A slot 2 port 12, commands A and D are required. Command A sets the direction of traffic monitoring to both receive and transmit directions, while command D activates the Ethernet traffic monitoring session. The other commands are not needed or incorrect for this configuration. Command B uses the wrong syntax for creating the destination interface, command C uses the wrong keyword for setting the direction, and command E uses the wrong syntax for creating the Ethernet traffic monitoring session. References:

The last packet indicates a DHCP Release message, which is sent by the client to the DHCP server to release the assigned IP address. This is typically done when the client no longer requires the IP address, or before the client shuts down to ensure the IP address can be reassigned. The packet capture showing a DHCP Release message confirms that the client is informing the DHCP server that it is releasing its current IP address.

References := For further understanding of DHCP operations and troubleshooting connectivity issues, the Cisco Data Center Core Technologies source book provides detailed explanations. Additionally, Cisco’s official documentation and resources on their website offer extensive guidance on managing and troubleshooting DHCP in Cisco environments. These materials are essential for network engineers working with Cisco Nexus series switches and dealing with DHCP-related issues.

 In Cisco ACI, TCAM resources can be optimized by configuring a single contract that is provided and consumed by all EPGs within a VRF. This approach ensures that all EPGs consume the same services, thus reducing the number of individual contracts and associated TCAM entries. By having a common contract, the ACI fabric can efficiently manage access control policies and service insertion without the need for multiple, redundant entries in the TCAM, which can lead to resource exhaustion. References: The information is based on the best practices for TCAM management in Cisco ACI fabrics, as detailed in the Cisco community discussions and Cisco’s official documentation on TCAM resource issues and workarounds12. Additionally, the concept of using a single contract for multiple EPGs is supported by the Cisco ACI Endpoint Security Group (ESG) Design Guide, which outlines the steps for implementing a single ESG for open communication between subnets (EPG selectors)

Option C meets the security requirements for the Cisco UCS C-Series Server. It disables unencrypted communication by enabling HTTPS, sets the session timeout to 900 seconds (15 minutes), redirects HTTP to HTTPS to divert unencrypted traffic, and changes the SSH port to a nondefault value (2022), which is essential for CLI-based management.

References := For further details on securing Cisco UCS C-Series Servers, refer to the Cisco UCS C-Series Servers Integrated Management Controller CLI Configuration Guide, which provides instructions on configuring service profiles, security settings, and management access.

 The command set in Option C correctly outlines the steps to configure a named VSAN called “VSAN10” with the specified requirements. It includes creating the VSAN with ID 10, assigning an FCoE ID of 20, and attaching it to port 2 in slot 1.

References := Detailed commands and configurations for VSANs can be found in the Cisco Data Center Core Technologies documentation, particularly in the sections that cover Fibre Channel switch mode and VSAN configuration

For traffic monitoring with fabric failover enabled, it’s important to ensure that traffic can still be analyzed even if one of the fabric interconnects fails. By creating two separate traffic monitoring sessions, each with a unique name and connected to an analyzer on each fabric interconnect, you can maintain continuous monitoring. This setup ensures that traffic is sent to the analyzer regardless of the state of either fabric interconnect.

 In a Cisco NX-OS environment, Ansible requires the NX-API to be enabled for HTTP/HTTPS protocol communication. NX-API is a REST-like API for NX-OS, providing a method for external applications to access the switch over HTTP/HTTPS, allowing for both CLI and simple object-based programming. This is necessary for Ansible to manage the device and execute automation tasks over these protocols.

References: Cisco’s official documentation on NX-API and Ansible’s documentation for Cisco NX-OS support.

 The solution that meets the requirements for implementing an automation solution to allow the backup of the configuration of Cisco Nexus series switches to a centralized location is the Guest Shell. The Guest Shell is a Linux-based container that runs on the Cisco Nexus operating system and provides a secure environment for running Python scripts and custom applications. The Guest Shell supports the RPM packaging format, which allows the team-developed custom monitoring scripts to be easily installed and managed. The Guest Shell is isolated from the underlying Cisco Nexus operating system, which means that it has no impact on the operating system if the resource contention occurs. The Guest Shell also allows the use of Python to expand the existing automation framework, such as using the NX-API or the Cisco Nexus Python SDK to interact with the switch configuration and state. References :=

 To ensure that vPC and non-vPC switches receive the same STP bridge ID from the upstream vPC switch peers, the engineer must implement the peer-switch feature on the vPC domain. The peer-switch feature allows the two vPC peer switches to act as a single logical switch for STP purposes, and to use the same bridge ID and priority. This way, the downstream switches will see the vPC peer switches as a single STP root, and will not have any STP loops or inconsistencies. The peer-switch feature also improves the convergence time and reduces the number of STP instances required in the network. References :=

Placing all EPGs in the preferred group within a VRF allows for communication between them without the need for additional contracts. This is because the preferred group feature in Cisco ACI allows EPGs within the same VRF to communicate with each other by default, bypassing the need to provide and consume contracts1. This simplifies the configuration process when new EPGs and bridge domains are added, as they inherit this communication capability by being part of the preferred group1.

References := For more information on the implementation of VRFs and the use of the preferred group feature in Cisco ACI, you can refer to the Cisco documentation on “Use vzAny to Automatically Apply Communication Rules to all EPGs in a VRF” and other related resources1. These documents provide detailed guidance on how to configure VRFs and EPGs to achieve seamless communication within the network infrastructure.

To establish a VSAN trunk between Switch 1 and Switch 2, you would typically configure E Port with Trunk Mode On. This is because Switch 1 is already configured with an E port in Trunk Mode Auto, and for trunking to be established, the other switch should also be set to trunk mode but with a static configuration (On) to ensure compatibility and trunk formation.

 The correct data structure to use within a POST message to receive a login token when configuring the Cisco APIC via REST API calls is an XML payload that includes the  tags with nested  and  tags for the username and password. This structure is shown in Option A, which is the standard format for authentication requests to the Cisco APIC.

References := For more detailed information, please refer to the Cisco APIC REST API Configuration Guide, which provides comprehensive instructions on using REST API for system configuration, including authentication and token retrieval processes.

When downloading a firmware image to a Cisco UCS Fabric Interconnect, especially from a remote location, it is crucial to use a protocol that provides both encryption and authentication to ensure the security and integrity of the file transfer. HTTPS (Hypertext Transfer Protocol Secure) is the protocol that meets these requirements. It is widely used for secure communication over a computer network within a web browser, with encryption provided by Transport Layer Security (TLS), which ensures that the transfer of the firmware image is secure and authenticated1.

 Static ingress replication is a method used in VXLAN environments where the replication of multicast, broadcast, and unknown unicast traffic is manually defined. In the context of Cisco Data Center Core Technologies, Option A implements static ingress replication by explicitly specifying peers for replication using the ingress-replication protocol static command followed by the peer-ip command to define the IP address of the replication peer. This configuration is necessary when multicast routing is not an option in the underlay network.

References := For further details, one would typically refer to Cisco’s official documentation on VXLAN configurations and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) study materials, which provide in-depth explanations on the setup and management of network overlays including static ingress replication.

 The ‘priv’ security level in SNMPv3 provides both authentication and encryption, ensuring that SNMP trap messages are both authenticated and protected from disclosure. This level uses a combination of a username and a strong authentication and encryption mechanism to secure the messages

 Configuring Link Group Preference to Port Channel © allows the use of all four interfaces and provides link failure tolerance. This is because port channels can combine multiple physical links into a single logical link that provides high availability through redundancy. If one link in the port channel fails, traffic is automatically redistributed to the remaining links without any disruption to the network12.

References: The configuration of port channels and link group preferences in a Cisco UCS environment is detailed in Cisco’s official documentation and community discussions related to fabric failover and high availability

 In Cisco ACI, an interface policy group can be linked to multiple Attachable Access Entity Profiles (AAEPs) to support connectivity for various EPGs with L3Outs. This setup allows for the concurrent support of L3Out connectivity and multiple EPGs on a single access port. References: This concept is covered in the section on ACI access policies in the DCCOR course.

The Python code snippet provided imports the json module and loads a JSON file into a variable named var1. Since JSON files inherently represent object data as dictionaries in Python, the resulting data structure is a dictionary. This is evident from the output shown, which displays a dictionary with nested dictionaries and lists, containing keys like ‘bd’, ‘ap’, ‘name’, etc., and corresponding values.

References := The explanation is based on standard Python data structures and JSON file handling as described in Python documentation and typical Python programming resources. JSON objects are represented as dictionaries in Python, which is a fundamental concept in working with JSON data in the language.

 Network-attached storage (NAS) provides the virtualization feature of a VM cluster shared disk. This allows multiple virtual machines to access shared storage, enabling functionalities like migration, fault tolerance, and distributed resource scheduling.

Cisco DCNM with SAN Insight is the solution that provides detailed information on the status of storage targets, including capacity metrics. SAN Insight is a feature within Cisco DCNM that allows storage administrators to monitor and analyze storage network traffic, helping to identify and resolve issues such as unexpected capacity limits. It would be the appropriate tool for creating and submitting a daily report of the environment showing the status of storage targets with the highest capacities.

 To discover a new chassis and establish all links from the chassis to the LAN network in a Cisco UCS domain with a vPC setup, the chassis discovery policy action should be set to one link. The Ethernet ports Eth1/1 and Eth1/2 should be configured as uplink Ethernet ports, and the link group preference should be set to Port Channel. This configuration ensures that the new chassis is properly discovered and that the links are correctly established to handle the LAN traffic.

References: The Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course provides detailed instructions on chassis discovery and vPC configuration. For further guidance, Cisco’s official documentation on vPC best practices and configuration examples would be the appropriate references

 To allow Layer 2 connectivity between Host 1 in VLAN 100 located in DataCenter 1 and Host 2 in VLAN 200 located in DataCenter 2, the correct OTV VLAN mapping configuration is option C. This configuration involves mapping VLAN 100 to VLAN 200 across the OTV overlay so that hosts in these separate VLANs can communicate as if they were in the same Layer 2 domain. The VLAN mapping is achieved by configuring the OTV edge devices in both data centers to associate the VLANs with each other.

Cisco HyperFlex uses the Network File System (NFS) protocol for sharing data among nodes in a VMware vSphere environment. NFS is a distributed file system protocol that allows a user on a client computer to access files over a network in a manner similar to how local storage is accessed. This protocol is commonly used in virtualized environments for ease of data sharing and management12.

References: The use of NFS in Cisco HyperFlex environments is documented in Cisco’s official installation guides and design documents

In Cisco UCS, modifying user accounts involves several considerations. Disabling a user account does indeed maintain all the data in the Cisco UCS Fabric Interconnect, which means that the user’s settings and privileges are retained even though the account is inactive (A). Local user accounts have precedence over remote authentication server accounts. This means that if a user account exists both locally and on a remote server like TACACS, RADIUS, or LDAP, the local account settings will take priority (D).

References := Managing User Accounts - Cisco1.

The correct command set is Option C, which includes the command fcdomain fcid persistent vsan 120. This command ensures that the Fibre Channel IDs (fcid) are saved across reboots for VSAN 120, meeting the requirement for persistent Fibre Channel IDs. The other commands in Option C are used to set the WWN and fcid as per the given requirements.

The DHCP snooping feature acts as a firewall between untrusted hosts and trusted DHCP servers. It validates DHCP messages received from untrusted sources and filters out invalid messages. To implement this on a Cisco Nexus 7000 Series Switch for VLAN 10, you would enable DHCP snooping for that VLAN and then configure the specific interface connected to the legitimate DHCP servers to be trusted. This ensures that DHCP responses from the legitimate servers are allowed, while responses from any other servers are blocked.

The statement that applies to a Cisco Nexus 5600 Series switch when performing a rollback is that errors are skipped when an atomic rollback type is triggered. An atomic rollback is a type of rollback that implements the checkpoint configuration only if no errors occur during the process. If any errors are encountered, the rollback is aborted and the running configuration is restored to its previous state. This ensures that the switch does not end up in a partially configured or inconsistent state. The other statements are not true because:

• A user who is assigned to the network-operator user role cannot perform a rollback. The network-operator user role has read-only access to the switch and cannot modify the configuration. To perform a rollback, the user must have the network-admin or vdc-admin user role.
• The configuration rollback functionality is not disabled when FCoE is enabled. The rollback feature is supported on all Cisco Nexus 5600 Series switches regardless of the FCoE configuration. However, some FCoE-related commands may not be rolled back due to dependencies or conflicts with other features.
• A system checkpoint is not generated automatically when the running configuration is saved to NVRAM. A system checkpoint is a predefined checkpoint that contains the last saved configuration of the switch. A system checkpoint is created or updated only when the user explicitly saves the running configuration to the startup configuration using the copy running-config startup-config command or its alias, copy run start. References: For more details on how to configure and use the rollback feature on a Cisco Nexus 5600 Series switch, please refer to the following resources:

When configuring traffic capture to investigate issues such as buffering problems and packet drops, it’s important to consider where to place the capture points. Typically, you would configure a SPAN (Switched Port Analyzer) or RSPAN (Remote SPAN) session to mirror the traffic from the affected areas to a monitoring device. The configuration would involve:

• Identifying the source ports or VLANs where the issues are observed.
• Specifying a destination port connected to a network analyzer like Wireshark.
• Ensuring the destination port is not used for regular network traffic.

For example, a basic SPAN session configuration might look like this:

monitor session [session_number] source interface [interface_id]

monitor session [session_number] destination interface [destination_interface_id]

References: The Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course provides insights into the capabilities of Cisco devices for traffic capture and monitoring. For detailed steps and best practices, refer to Cisco’s official documentation on configuring packet capture

The configuration in Option C likely involves setting the port to N Port and enabling Trunk Mode Active. This setup is necessary for establishing a VSAN trunk, as it allows the port to actively negotiate with the other switch to transmit and receive frames in multiple VSANs over the same physical link1.

 Option D is the correct choice. Configuring the vPC role priority and enabling the peer-gateway feature are recommended practices for enhancing vPC convergence times. The peer-gateway feature allows for local forwarding of packets without the need to cross the vPC peer link, which can significantly reduce convergence times during primary peer device failures and recoveries. This approach ensures that the vPC system can quickly adapt to changes and maintain traffic flow even in the event of a device failure123.

References: For more detailed information and best practices, you can refer to Cisco’s official documentation and community discussions on vPC convergence and failure scenarios

 The two components that support specific power limits on a Cisco UCS C-Series rack server are the processor and the graphic card. The processor and the graphic card are the two components that consume the most power on a server, and they can be configured to have specific power limits to control the power usage and performance of the server. The power limits can be set using the Cisco Integrated Management Controller (CIMC) web interface or CLI, or using the Cisco UCS Manager if the server is integrated with a Cisco UCS domain. The power limits can be applied to individual processors or graphic cards, or to the entire server. The power limits can help to optimize the power efficiency and thermal management of the server, as well as to prevent power capping or throttling issues. References :=

 Option D and C are the correct policies that must be configured to meet the requirements. A Maintenance Policy specifies how the changes are applied when a service profile is associated or disassociated with a server or when an updated service profile is applied to a server. A Power Control Policy allows users to select how Cisco UCS Manager should restore power to the servers in a chassis after the chassis loses power. References:

 SSH (Secure Shell) is the protocol that allows secure remote login from one computer to another. It provides strong authentication and secure communications over unsecured channels. This protocol is preferred for automated onboarding of devices like Cisco Nexus 9000 Series Switches because it supports strong encryption and credential-based authentication, which aligns with the requirement for minimal connection methods and security. SSH is commonly used in network automation for secure command execution and file transfers.

References := For more information on configuring Cisco Nexus 9000 Series Switches for automation and integration with systems like Cisco UCS Director, you can refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide, which details the supported manageability features and advanced automation capabilities, including Power On Auto Provisioning (POAP) and integration with automation frameworks

 In a vPC (Virtual Port-Channel) configuration, multicast traffic is handled based on the vPC design and operational rules. When a host sends traffic to a multicast group, the vPC switches determine the forwarding path based on the source and the vPC domain configuration. If multicast traffic is received on a vPC member port, such as Po10 on Switch1, the traffic is typically forwarded out on all ports that are part of the same VLAN and have receivers interested in the multicast group, which includes Po1 and Po20 in this case. This ensures that the multicast traffic reaches all intended recipients across the vPC domain.

References: For a comprehensive understanding, the Cisco documentation on “Multicast forwarding in vPC based on location of the source” provides detailed scenarios and explanations on how multicast traffic is forwarded in a vPC environment1. Additionally, the “Cisco Nexus 9000 Series NX-OS Multicast Routing Configuration Guide” offers insights into the configuration and behavior of multicast routing on Nexus switches, which can be applied to understand the vPC behavior with multicast traffic

A Multi-Site Orchestrator deployment requires two orchestrators to be deployed, one in each of the two main data center sites. The Multi-Site Orchestrator is a software component that enables the management and orchestration of multiple Cisco Application Centric Infrastructure (ACI) fabrics that are geographically distributed across different locations. The Multi-Site Orchestrator provides a single pane of glass for configuring, monitoring, and troubleshooting the ACI fabrics, as well as synchronizing policies and tenants across the sites. The Multi-Site Orchestrator also supports disaster recovery and high availability scenarios by allowing the replication of data and services between the sites. The Multi-Site Orchestrator deployment consists of two orchestrators that form a cluster and communicate with each other using a secure channel. Each orchestrator is connected to one or more ACI fabrics in the same site, and acts as a proxy for the other orchestrator to access the ACI fabrics in the remote site. The orchestrators use a leader-election algorithm to determine which one is the active orchestrator and which one is the standby orchestrator. The active orchestrator handles all the requests from the users and the applications, while the standby orchestrator monitors the health and status of the active orchestrator and takes over in case of a failure. The orchestrators also perform periodic data synchronization to ensure consistency and reliability. References :=

POAP is an automatic provisioning and zero-touch deployment feature that assists device owners in the

initial deployment and configuration of Nexus switches.

The feature works by checking for a local configuration script. If the script has been deleted, the switch has

been reset to factory settings, or this is the first boot-up, the POAP daemon will connect to a preset list of

servers to download an initial configuration file.

To perform this operation, the switch must first obtain an IP address from a local DHCP server. POAP

configuration settings can also be passed through the DHCP response.

Which conditions should be verified, so they need to be TRUE. Like no startup (A) and bootup (B). C means

that it needs to miss a license file and E means it needs to miss an NX-OS image.

 In a vPC (Virtual Port-Channel) environment, multicast traffic is expected to be replicated to the ports that have joined the multicast group and also across the peer link. This ensures that in case of a failure scenario, orphan ports, which are ports not part of the vPC and only connected to one of the vPC peer switches, still receive the multicast stream. Option C correctly describes this behavior, where the multicast traffic is replicated to the ports that joined a given multicast group and the peer link, and the multicast traffic stream flows over the peer link to ensure that orphan ports receive the multicast stream in failure scenarios12.

References: = For a more in-depth understanding of multicast traffic flow in a vPC environment, you can refer to Cisco’s official documentation on multicast forwarding in vPC based on the location of the source1, as well as community discussions and technical articles available on the Cisco Community website

The configuration must ensure that the SPAN session captures traffic from the file server’s VSAN to the destination interface connected to the FC analyzer. The commands provided in the exhibit show the setup of a SPAN session with the destination interface as port-channel 2 and the source interface as VSAN 100, which is likely the VSAN associated with the file server.

References := For more detailed information and step-by-step guidance on configuring SPAN sessions on Cisco MDS 9000 Series Switches, you can refer to the official Cisco documentation on Implementing and Operating Cisco Data Center Core Technologies (DCCOR) available at Cisco’s training and certifications page and the Cisco Community knowledge base. These resources provide comprehensive insights into deploying, securing, operating, and maintaining Cisco data center infrastructure, including the Cisco MDS Switches.

To accomplish the goal of adding all devices already logged in and learned to the Fibre Channel active database, the customer should enable port security and device aliases on the Cisco MDS 9000 series switch. Port security is a feature that allows the switch to restrict the number and type of devices that can log in to a Fibre Channel port. Port security can be configured to automatically add the devices that are already logged in and learned to the active database, and prevent any unauthorized devices from logging in. Device aliases are user-friendly names that can be assigned to devices based on their World Wide Names (WWNs). Device aliases can be used to simplify the management and configuration of devices, as well as to enhance the security and visibility of the Fibre Channel network. Device aliases can also be automatically added to the active database along with the port security information, and can be used for zoning and other operations. References :=

 Creating a virtual iSCSI vNIC (B) is necessary for the server to perform an iSCSI boot from the storage array. This virtual iSCSI vNIC serves as an iSCSI boot firmware table (iBFT) configuration placeholder for iSCSI boot configuration. It is not an actual vNIC but is essential for the iSCSI boot process as it holds the configuration details required for the server to communicate with the storage array during the boot process1.

References: The process of configuring iSCSI boot in Cisco UCS Manager, including the creation of a virtual iSCSI vNIC, is detailed in Cisco’s documentation

 In Cisco Unified Computing System (UCS), a service profile’s UUID (Universally Unique Identifier) can be allocated from a UUID pool. This pool is predefined within UCS Manager and allows for consistent identity assignment across different hardware, enabling stateless computing. The UUIDs are not based on the hardware, not vendor assigned, and although they are unique, they are not system generated in this context; they are drawn from a pool created specifically for service profiles to ensure uniqueness and manageability within the UCS environment.

References: The concept of UUID pools and their use in service profiles is detailed in the Cisco Data Center Core Technologies documentation, particularly in sections discussing service profile creation and management within the UCS Manager. For a deeper understanding, the Cisco UCS Manager GUI Configuration Guide provides step-by-step instructions on how to create and assign UUID pools for service profiles.

 The System Configuration backup type in Cisco UCS Manager is specifically designed to back up system settings such as user names, roles, and locales. This XML file does not include the actual data on the servers but captures all the system configuration settings, which can be imported to the original fabric interconnect or to a different one. However, it cannot be used for a system restore.

 In the context of Bash scripting for system automation, the killproc command is often used to stop a process. The correct option to complete the script for a Chef Client reload would involve sending a HUP (hang-up) signal to the Chef Client process, which is typically done to cause the process to reload its configuration without stopping the service. The command killproc -p $pidfile $exec --HUP would send the HUP signal to the process identified by the pidfile, which is the expected behavior for a Chef Client reload on a system reset.

References := For a detailed explanation and official documentation, the Cisco Data Center Core Technologies source book or study guide should be consulted, as well as the official Chef documentation which provides information on system and service management commands.

The PowerShell command in option D is the correct choice for automating the removal of switches from VLANs using the Cisco UCS Manager PowerShell module. This command uses environment variables to specify the VLAN name and switch identifiers, ensuring that the VLAN persists even when it is no longer associated with the switch port. The command structure allows for the removal of the VLAN association from the switch port without deleting the VLAN itself, thus maintaining the VLAN configuration for potential future use.

References: The explanation is based on the Cisco UCS Manager PowerShell module documentation, which provides details on scripting and automation capabilities for managing Cisco UCS environments.

 Embedded Event Manager (EEM) is a powerful tool used in Cisco devices, including MDS switches, to automate tasks and create custom scripts that react to network events. For an administrator needing to configure an automated policy to shut down a link when a threshold is exceeded, EEM is the appropriate feature to use. It allows the creation of event-driven automation scripts that can be triggered when certain conditions are met, such as a link exceeding a specified threshold.

References: Cisco Data Center Core Technologies (DCCOR) training materials and Cisco’s official documentation on EEM.

 The Cisco Integrated Management Controller (IMC) is a system management component built into Cisco UCS C-Series servers. When the IMC is upgraded, it disrupts the Keyboard, Video, Mouse (KVM) sessions that are used for remote server management. This is because the IMC upgrade process requires a reboot of the controller, which temporarily disconnects any active KVM sessions. However, it does not affect Cisco UCS Manager, SAN traffic, or data traffic, as these components operate independently of the IMC.

 The device-alias confirm-commit command is used in Cisco MDS 9000 Series Switches to ensure that changes made to device aliases are confirmed before being committed to the database. This command prompts the user for confirmation and displays the pending changes explicitly on the console, which aligns with the requirements stated in the question.

References: For more detailed information, you would typically refer to the Cisco Data Center Core Technologies study guide or the official Cisco documentation for the MDS 9000 Series.

To complete the PowerOn Auto Provisioning (POAP) operation on a Cisco Nexus 9000 Series Switch, the script must include the necessary network information such as the interface IP address, gateway, and DNS server IP addresses. Option C likely contains this information, which is essential for the switch to locate a DHCP server, bootstrap itself, and download the configuration script for software image installation and configuration

The output indicates that port channel 1 is trunking, which means it is configured to be an Inter-Switch Link (ISL). ISLs are used in Fibre Channel networks to connect switches and maintain the fabric topology. The “port mode is F” in the output also confirms that it’s an ISL, as F-ports are used for Fabric (switch) ports connecting to N-ports on another switch or node.

Two capabilities of the Cisco Network Assurance Engine are that it validates that devices comply with network security policies and that it predicts the impact of changes to the network. The Cisco Network Assurance Engine is a software solution that uses mathematical modeling and verification techniques to continuously analyze the state and configuration of the data center network. It can validate that the network devices are compliant with the intended security policies, such as access control lists, firewall rules, and encryption standards. It can also predict the impact of planned or unplanned changes to the network, such as software upgrades, configuration changes, or device failures, and provide proactive recommendations to avoid or resolve issues. The Cisco Network Assurance Engine helps to ensure that the network is always operating as intended and aligned with the business objectives. References :=

The method that a network engineer must use to upgrade the BIOS firmware of a Cisco UCS standalone C-Series rack-mount server is to use the Cisco host upgrade utility. The Cisco host upgrade utility is a tool that allows the network engineer to upgrade the firmware of various components of the server, such as the BIOS, the CIMC, the RAID controller, and the network adapter. The Cisco host upgrade utility can be downloaded from the Cisco website and run from a bootable USB drive or CD-ROM. The Cisco host upgrade utility provides a graphical user interface that guides the network engineer through the firmware upgrade process, and allows the network engineer to select the firmware versions and the components to be upgraded. References :=

The statement that is true about the behavior of multiple roles applied to a user on the Cisco MDS 9000 Series Switch is that access to a command takes priority over being denied access to a command. This means that if a user has multiple roles assigned and one of the roles grants access to a command while another role denies access to the same command, the user will be able to execute the command. The access permission overrides the deny permission in case of a conflict. The other statements are not true because:

• Any commands that have conflicting settings between roles are not denied. As explained above, the access permission prevails over the deny permission in case of a conflict.
• The first role assigned does not take precedence over subsequent roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied.
• The last role assigned does not take precedence over previous roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied. References: For more information on how to configure and manage roles on the Cisco MDS 9000 Series Switch, please refer to the following resources:

To prevent data corruption due to cross fabric communication in an FCoE environment, the network engineer must apply the configuration Switch(config)#fcoe fcmap 0e,fc,2a to the Cisco Nexus Unified Switches. This configuration sets the FCoE MAC address prefix (fcmap) to a custom value of 0e,fc,2a, which is different from the default value of 0e,fc,00. The fcmap is used to identify the FCoE traffic and map it to the corresponding Fibre Channel ID (FCID). By using a custom fcmap, the network engineer can avoid the possibility of FCID conflicts or overlaps between different FCoE fabrics, which can cause data corruption or loss. The custom fcmap must be configured on all the switches in the same FCoE fabric, and must be unique across different FCoE fabrics. References :=

 NFS, or Network File System, is a file service protocol that allows files to be accessed over a network in a manner similar to how local storage is accessed. NFS provides the capability for clients to view, store, and update files on a remote Linux-based storage repository. It is widely used as a distributed file system standard for Network Attached Storage (NAS) because it allows the files to appear locally mapped to the client, facilitating easy file sharing and management1.

References := The use of NFS in NAS environments is well-documented in Cisco Data Center Core Technologies source documents and study guides, which explain how NFS works and its role in providing distributed file system services

Upgrading the EPLD on a Cisco Nexus switch is a disruptive process that requires the switch to reboot multiple times. Each EPLD device on the switch must be upgraded individually, and the switch must reboot to initialize the new EPLD version for each device. This process ensures that all hardware components are properly updated and can operate with the new firmware, but it does cause temporary disruptions to network traffic as each module reboots.

References: For more detailed information, please refer to the Cisco Nexus 9000 Series FPGA/EPLD Upgrade Release Notes, where it discusses the impact of EPLD upgrades and the necessity of multiple reboots during the process1. Additionally, the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide provides guidelines on the upgrade process, including the disruptive nature of EPLD upgrades

 Option C is the correct answer. Puppet is an open-source software configuration management tool that is used for deploying, configuring, and managing servers. It allows for the centralized management of various system configurations and aligns UCS servers to their desired state by periodically acquiring configurations from a centralized server. References:

 In a VXLAN data center fabric, inter-VNI communication requires mapping Layer 2 (L2) VLANs to their respective L2 VNIs and associating them with the correct Layer 3 (L3) VNI that corresponds to the VRF. In this case, VLAN 100 is mapped to L2 VNI 2020, and for inter-VNI routing to occur, it must be associated with an L3 VNI that corresponds to the VRF, which is Test_Telco_VRF to L3 VNI 1010. References: For more detailed information, you can refer to the Cisco Programmable Fabric with VXLAN BGP EVPN Configuration Guide1 and the Data Center VXLAN EVPN guide

The Cisco UCS firmware Auto Sync Server policy includes several configuration settings that determine how and when firmware on servers is synchronized. The two available settings from the options provided are ‘User Acknowledge’ and ‘No Action’. ‘User Acknowledge’ requires an administrator to manually acknowledge firmware upgrades in the Pending Activities dialog box before they are applied. ‘No Action’ means no firmware upgrade is initiated on the server. These settings allow administrators to control the firmware synchronization process according to their operational policies and procedures.

References := Using Firmware Automatic Synchronization Server Policy - Cisco, Cisco UCS B-Series CLI Firmware Management Guide, Release 2.2

To ensure that the Cisco Nexus 7000 series switches are the primary devices for LACP, the configuration must use the lacp system-priority command to assign a lower priority value to the switches. This command determines which device is the active partner in an LACP negotiation. The lower the priority value, the higher the preference. In option A, the switches have a priority value of 1, which is the lowest possible value and the highest preference. Therefore, option A is the correct configuration to make the switches the primary devices for LACP.

References := The explanation is based on the official Cisco documentation on Configuring Link Aggregation Control Protocol (LACP) 1, specifically the section on Configuring LACP System Priority.

SPAN (Switched Port Analyzer) is a feature that allows network traffic from one or more source ports to be mirrored to a destination port for analysis. When configuring SPAN on a Cisco Nexus 5000 Series switch, two characteristics must be considered:

• A SPAN source port can be monitored in multiple SPAN sessions. This means that the same port can send traffic to different destination ports for different purposes or applications.
• A SPAN source port cannot be a destination SPAN port. This means that a port cannot receive traffic from another port that it is already monitoring. This prevents loops and conflicts in the SPAN configuration.

To meet the specified requirements, a custom role needs to be created for User1 that grants full access to both the Fabric Interconnect infrastructure and network security operations, as well as storage operations configuration. This custom role ensures that User1 has the necessary permissions across different areas of the UCS Manager. Using LDAP for role-mapping with Active Directory allows for the integration of UCS Manager with the existing AD infrastructure, enabling centralized management of user credentials and access rights12.

References := The process for integrating Cisco UCS Manager with Active Directory and configuring custom roles can be found in the official Cisco documentation, such as the Cisco Secure Access Control System Configuration Guides and the Cisco Community discussions on UCS Manager and Active Directory integration12. These resources provide step-by-step instructions and best practices for setting up access control in UCS Manager using Active Directory.

The OPTIONS method is used in REST APIs to return the HTTP methods that the server supports for a specific URL. This can be useful for discovering what functionality a REST API endpoint supports.

 To meet the objective of sending a copy of all VLAN 11 traffic on N5K_1 to the Traffic Capturing Device, creating a LAN traffic monitoring session is the necessary action. This session will capture the specified VLAN traffic and forward it to the designated capturing device for analysis or monitoring purposes. The existing configuration in Cisco UCS Manager needs to be complemented with this session to achieve the desired traffic capture.

In a multihomed OTV network, it is essential to configure the remote OTV AEDs (Authoritative Edge Devices) to use both the primary and secondary adjacency servers for redundancy and resiliency. The correct configuration, Option D, includes the otv use-adjacency-server command with both IP addresses of the primary and secondary servers followed by unicast-only, which indicates that the AEDs should use unicast connections to the adjacency servers instead of multicast.

References := This configuration aligns with best practices for setting up OTV networks as described in Cisco’s Data Center Core Technologies documentation. For a more comprehensive understanding, refer to the study materials related to OTV configurations in the Cisco Data Center Core Technologies (DCCOR) course.

Cisco IMC software policy is used to install new Cisco IMC software on a server. This policy allows the administrator to specify the desired Cisco IMC software version and the schedule for the installation. The other policies are used to manage different aspects of the server firmware, such as the host firmware, the hypervisor firmware, and the BIOS software. References:

The impact of the EPLD update of the supervisor module on the Cisco MDS 9000 switches is that the redundant supervisor takes over while the EPLD update is in progress and there is no service disruption. EPLD (Electronic Programmable Logic Device) is a firmware component that controls the functionality of various hardware modules on the switch, such as the supervisor, line cards, and fabric modules. The EPLD update is performed to enhance the performance and features of the hardware modules, and to fix any bugs or issues. The EPLD update process requires a reload of the affected module, which can cause a temporary loss of connectivity and traffic. However, if the switch has a redundant supervisor module configured in high availability mode, the EPLD update can be performed without any service disruption. This is because the redundant supervisor takes over the control plane functions while the active supervisor is being updated, and then switches back to the active supervisor when the update is completed. The EPLD update does not affect the data plane traffic, as the line cards and fabric modules continue to forward packets during the update process. References :=

EIGRP authentication is used to prevent unauthorized devices from forming neighbor relationships. The correct CLI commands to establish EIGRP neighborship with authentication on Cisco Nexus switches involve configuring the interface with EIGRP, setting the EIGRP autonomous system number, and specifying the authentication key and key-chain. The commands in Option A are consistent with these requirements, hence it is the verified answer.

 The ‘iqn_pool’ attribute in Ansible is used to apply iSCSI initiator identifiers to all iSCSI vNICs for service profiles derived from a service template. This ensures that each iSCSI vNIC has a unique identifier for storage communication2

 An EPLD (Electronic Programmable Logic Device) upgrade on a Cisco Nexus 9000 Series Switch is used to upgrade the field-programmable gate arrays (FPGAs). FPGAs are integrated circuits that can be configured by a customer or a designer after manufacturing – hence “field-programmable”. They are used in Cisco switches to provide hardware functionalities in all modules, and EPLD image upgrades enhance hardware functionality or resolve known issues1.

When there is a domain name change, and the Cisco UCS Manager needs to be available over HTTPS, generating a new default key ring certificate from the Cisco UCS Manager (B) is typically the recommended action. This ensures that the HTTPS service has a valid certificate that matches the new domain name.

 A logical backup includes all logical configuration settings such as service profiles, VLANs, VSANs, pools, and policies1. Since the end users are only allowed to make changes to the Service Profile configuration, a logical backup is appropriate as it will capture the state of these configurations without including system settings. Scheduling the logical backup at the start of the weekend ensures that the latest configurations are saved before any changes occur. Scheduling the import of this backup on Monday morning will restore the configurations to their state at the time of the backup, thus reverting any changes made by the end users during the weekend1.

References := The Cisco UCS Manager documentation provides detailed instructions on how to schedule backups and imports, which can be found in the official Cisco resources1. These documents outline the steps for setting up scheduled backups and imports, ensuring that the UCS Manager configuration can be restored to a specific state as required.

The configuration shown in the exhibit indicates that FCIP (Fibre Channel over IP) is configured with ip-compression mode2 enabled on a Cisco MDS 9000 Series switch. This means compression is performed by using software (Option D), as mode2 refers to software-based compression in FCIP configurations. The other options are not correct based on the configuration. The switch does not attempt to make two TCP connections, as there is no tcp-connections command in the configuration. Compression is not performed by using hardware, as mode1 refers to hardware-based compression in FCIP configurations. Mode2 is not enabled by default, as the default mode for FCIP compression is none. References:

A full state configuration backup in Cisco UCS Manager includes a snapshot of the entire system, which is stored as a binary file. This backup type is ideal for disaster recovery as it can restore or rebuild the configuration on the original fabric interconnect or recreate the configuration on a different fabric interconnect. It is important to note that this backup type cannot be used for an import but is specifically designed for system restoration.

NFS (Network File System) is a distributed file system protocol that allows users on client computers to access files over a network in a manner similar to how local storage is accessed. NFS uses a Kerberos-based security model to provide authentication, integrity, and confidentiality of data. It ensures that unauthorized users do not have access and protects the data from eavesdropping and tampering as it moves across the network. The other options are not features of NFS. Role-based access control is a method of restricting access to resources based on the roles of users. Block-based file access is a type of storage access that transfers data in fixed-sized blocks. Zone-based access control is a feature of Fibre Channel SANs that allows traffic isolation within a VSAN. References:

 Including EPG-2, EPG-3, and EPG-4 in the preferred group allows these EPGs to communicate with each other without requiring any contracts. This is because the preferred group feature in Cisco ACI allows EPGs within the same VRF to communicate by default. However, since the secure server in EPG-1 must provide services to EPG-2, a contract is required between EPG-1 and EPG-2 to facilitate this communication while maintaining the security and policies necessary for the server.

References := For more detailed information on configuring EPGs and contracts in Cisco ACI, you can refer to the Cisco Data Center Core Technologies (DCCOR) study materials and official Cisco documentation. These resources provide comprehensive guidance on the implementation and management of EPGs, contracts, and preferred groups within a Cisco ACI environment.

1. set the format and destination to which the data is sent.

2. configure the data to be collected as part of the sensor group.

3. set the subscription between the sensor-group and the destination.

When connecting a Cisco UCS Fabric Interconnect (FI) directly to an external storage array using a Fibre Channel (FC) storage port, it is essential to configure the FI in FC switch mode. This mode allows the FI to manage FC traffic and zoning, which is necessary when bypassing an upstream SAN switch. Additionally, creating the required Virtual Storage Area Network (VSAN) within the SAN cloud is crucial for isolating and managing the traffic between the FI and the storage array. The VSAN provides a unique identifier that enables the direct connection and communication between these devices.

References: The configuration steps for direct attachment of a storage array to a Cisco UCS FI are detailed in Cisco’s official documentation and support forums1. Specifically, the process involves setting the FI in FC switch mode and creating the necessary VSAN for the connection1. These references provide guidance based on Cisco’s recommended practices for such configurations.

 Option C is the correct attribute to use to assign the servers to different microsegments based on their VM names. By doing this, IT security can enforce policies that isolate production from development database servers existing in the same EPG and IP subnet. This can be achieved by using the microsegmentation feature of Cisco ACI, which allows granular control over the communication between endpoints within an EPG. References:

The new employee needs to add VLANs into an existing Cisco UCS Manager and configure NTP synchronization with date and time zone settings. Option B, Ext LAN Config (ext-lan-security), grants privileges to configure external LAN connectivity settings including VLANs. Option D, Service Profile Config (Is-config), allows for configuring service profiles including NTP synchronization settings. References:

To create an environment variable that can be used by several policies in the Embedded Event Manager, the engineer should use the command N9k2 (config)# event manager environment mailserver ‘’10.10.10.10’’. This command defines a global environment variable named mailserver with the value of 10.10.10.10, which represents the external email server. The environment variable can then be referenced by any policy that needs to use the email server in its actions, such as sending notifications or alerts. The environment variable can also be modified or deleted as needed. The other commands are incorrect because they either use the wrong mode, the wrong keyword, or the wrong syntax. References :=

To create a VSAN on the network, the engineer needs to select Fabric A from the drop-down menu. This will allow the engineer to assign a VSAN ID and a name to the new VSAN, and to add members to the VSAN. The other options are not relevant for creating a VSAN. Fabric B is the other fabric interconnect, FC Zoning Enabled is a feature that allows traffic isolation within a VSAN, and Common/Global is a default VSAN that cannot be modified. References:

The network administrator role in Cisco UCS Manager is designed to allow configuration of network-related settings, which includes vHBAs, vNICs, and server port types. This role provides the necessary privileges to manage these components

To ensure that the Cisco Nexus 7000 series switches are the primary devices for LACP, the system priority needs to be configured with lower values indicating higher priority. In this case, setting N7K_A with a system priority of 100 and N7K_B with a system priority of 200 ensures that N7K_A has a higher priority and becomes the primary device for LACP. The system priority is used in the LACP system ID which determines the LACP priority; the lower the value, the higher the priority.

References: The configuration guidelines for LACP on Cisco devices can be found in the Cisco documentation, which explains the role of system priority in determining the primary device in an LACP setup1. Additionally, the Cisco Data Center Core Technologies study materials provide detailed information on configuring LACP and vPC domain parameters.

The In-Service Software Upgrade (ISSU) process is designed to upgrade the system software with minimal disruption to the network. Nonstop forwarding (NSF) and stateful switchover (SSO) are two features that work together to maintain packet forwarding and switch state information during the ISSU process. NSF allows the router to continue forwarding packets even when the route processor is failing over, while SSO synchronizes state information between redundant route processors to ensure a seamless transition during a failover1.

References := For a deeper understanding of the ISSU process and its associated features, you can refer to Cisco’s official documentation on In-Service Software Upgrade (ISSU), which provides detailed information on how NSF and SSO contribute to a nondisruptive upgrade

The attribute that must be selected to implement microsegmentation of endpoints within the same IP subnet using a network-based attribute that allows IP subnet independence is the Tag attribute. The Tag attribute is a user-defined attribute that can be assigned to endpoints based on any criteria, such as location, function, or security level. The Tag attribute can be used to create microsegmentation policies in ACI, which define the rules for communication between endpoints within the same or different bridge domains. The Tag attribute enables IP subnet independence, which means that the microsegmentation policies are not tied to the IP subnet of the endpoints, and can be applied across different subnets or even different fabrics. The Tag attribute also simplifies the management and scalability of microsegmentation policies, as it does not require the use of IP addresses or MAC addresses to identify endpoints. References :=

The benefit of adding Cisco HyperFlex Hardware Acceleration Cards to a HyperFlex deployment is increased compression efficiency. These cards are PCIe devices that offload the compression and decompression operations from the CPU, resulting in higher performance and lower latency for most storage workloads. The cards also reduce the CPU utilization and power consumption of the HyperFlex nodes, enabling more resources for other applications. The other options (offline encryption acceleration, increased network throughput, and GPU acceleration) are not benefits of the HyperFlex Hardware Acceleration Cards. References: For more information on the HyperFlex Hardware Acceleration Cards, please refer to the following resources:

 Enabling the DHCP relay agent on a switch allows it to forward DHCP BOOTREQUEST packets from clients to a DHCP server, even if they are not on the same physical subnet. This is crucial for clients to obtain an IP address and other network configuration parameters from a DHCP server that is not locally present on the subnet.

References: Detailed information on DHCP relay agents can be found in the Cisco Data Center Core Technologies (DCCOR) study guide or source documents, particularly in the chapters discussing DHCP configuration and management in network environments.

To recover the configuration of the Cisco UCS Manager from a full backup available on a backup SCP server, the actions in Option A should be followed. These actions typically involve accessing the Cisco UCS Manager interface, navigating to the backup and restore settings, and initiating a restore operation using the SCP protocol to retrieve the backup file from the SCP server.

References: = For detailed steps and best practices, you can refer to the official Cisco documentation on “Backing Up and Restoring the Configuration” in the Cisco UCS Manager guide1.

 For a Cisco UCS C-Series Rack Server with PCIe cards, the fan configuration policy should be set to accommodate the additional cooling requirements of these cards. Option C, which sets the fan policy to ‘balanced’, would provide a middle ground between performance and energy efficiency, suitable for a server with additional components such as PCIe cards. This ensures adequate cooling while maintaining energy efficiency.

The action that must be performed before renumbering a Cisco UCS chassis is to re-acknowledge the chassis. Re-acknowledging the chassis is a process that forces the Cisco UCS Manager to rediscover the chassis and its components, such as the I/O modules, the power supplies, and the fans. Re-acknowledging the chassis is necessary before renumbering the chassis, because it ensures that the Cisco UCS Manager has the latest information about the chassis and its configuration. Re-acknowledging the chassis also allows the network engineer to apply any pending configuration changes or policies to the chassis and its components. Re-acknowledging the chassis can be done from the Cisco UCS Manager GUI or CLI, by selecting the chassis and choosing the Re-Acknowledge option. References :=

The configuration set in Option C is designed to invoke a Python script when the router becomes unreachable. It uses an event scheduler to track the state of the router and, if it is not up, it triggers the Python script “routerdown.py” at specified intervals. This setup ensures that the operations team is alerted promptly when the router DC-RTR-1 becomes unreachable, allowing for quick response and troubleshooting.

 The correct answer is option C. The fabric binding configuration in option C matches the output required for the Cisco MDS 9000 Series Switch. Fabric binding enhances the security of the SAN fabric by allowing only authorized switches to join the fabric. The configuration includes specifying the switch world wide name (swwn), domain ID, and member world wide node name (nwwn) to ensure that only the specified devices can participate in the fabric.

References: For more information on fabric binding and its configuration, you can refer to the Cisco MDS 9000 Series Fabric Switches Configuration Guide and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) study materials.

 In the provided configuration, the commands are used to configure a Fibre Channel interface on a Cisco Nexus 5000 Series switch. The “interface fc2/3” command is used to enter the interface configuration mode for the specified Fibre Channel interface. The “switchport mode sd” command configures the Fibre Channel interface for synchronization distribution (SD). SD is a feature that allows the distribution of clocking information through the network to synchronize different parts of a system.

References: The Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course provides detailed information on configuring Fibre Channel interfaces, including synchronization distribution12. Additional resources can be found in Cisco’s data center certification materials3

 To implement private VLANs for Cisco UCS 8-Series servers, the primary VLAN is already present, and the secondary VLAN needs to be added to both fabrics. The correct configuration set that accomplishes this task is Option C. This option includes the necessary commands to create the VLAN and set its sharing to secondary, which is required for the configuration of private VLANs in a Cisco UCS environment12.

References: = For detailed steps and configurations, refer to the Cisco documentation on private VLANs and UCS configuration12. It provides comprehensive guidance on setting up private VLANs in the Cisco UCS environment.

 The configuration in Cisco UCS Manager needs to specify the source of the traffic for the SPAN session. Since the requirement is to monitor the traffic from VSAN 11, selecting VSAN 11 as the source will direct the traffic to the monitoring session. This is consistent with the SPAN session’s purpose, which is to create a copy of the traffic for analysis or monitoring.

References := For more information on configuring SPAN sessions in Cisco UCS Manager, you can refer to the Cisco Data Center Core Technologies study materials and official documentation, which provide guidelines on setting up traffic monitoring solutions within a Cisco data center environment. These resources will offer detailed instructions and best practices for implementing SPAN sessions to monitor VSAN traffic.
