NSX managed compute endpoints are called Transport Nodes. A transport node is a host or a NSX Edge that has NSX modules installed and is registered with the NSX Manager.

A Software Defined Networking (SDN) solution has the following characteristics:

A. It allows workloads to be placed and migrated anywhere in the network: SDN abstracts the networking layer, enabling dynamic and flexible placement of workloads across the network without being tied to physical network constraints.

C. It is decoupled from the physical networking infrastructure: SDN separates the control plane from the data plane, allowing network management to be done via software, independent of the underlying physical hardware.

NSX Intelligence provides visibility and dynamic security policy enforcement in an NSX-T Data Center environment. It offers real-time monitoring and analytics, helping administrators to understand network traffic patterns and enforce security policies dynamically based on observed behavior.

The host transport node sa-esxi-04.vclass.local is successfully prepared for NSX with a Tunnel Endpoint (TEP) address of 172.20.11.151. This is evident from the "Success" status and the populated "TEP IP Address" field in the exhibit.

VMware NSX provides network virtualization capabilities within the virtual infrastructure layer of the Software-Defined Data Center (SDDC). NSX abstracts the network infrastructure away from the underlying hardware and provides a software-defined networking layer that allows for the creation, management, and automation of virtual networks.

To access the NSX Manager, you use the NSX UI with a supported browser. The NSX Manager provides a web-based user interface for managing and configuring the NSX environment. This UI is accessible via a web browser and does not require a dedicated fat client or telnet access. The vSphere Client can also access NSX Manager, but the primary method is through the NSX UI.

In a software-defined data center (SDDC) solution, the following three components are virtualized:

A. Compute: Virtualizing compute resources allows for the creation and management of virtual machines, providing flexibility and efficiency in resource allocation.

C. Storage: Virtualizing storage resources involves abstracting physical storage devices into a single logical storage pool that can be managed and provisioned as needed.

F. Network: Virtualizing network resources with solutions like NSX-T allows for the creation of virtual networks that are decoupled from physical network hardware, enabling greater flexibility and scalability.

To achieve routing between all segments in a network that consists of three tiers using NSX-T, the administrator can use gateways. Specifically, the use of Tier-0 and Tier-1 Gateways enables routing between different segments. The segments can be connected to a Tier-1 Gateway, which in turn can be connected to a Tier-0 Gateway to provide routing to external networks.

The component that provides virtual switching capabilities in NSX-T Data Center is the NVDS (NSX Virtual Distributed Switch). NVDS allows for the creation and management of virtual networks within the NSX-T environment, supporting advanced network functions like distributed switching, routing, and firewalling.

To create NSX-T objects from code, an administrator should use the REST API. The NSX-T REST API allows administrators to automate and manage NSX-T resources programmatically. It provides comprehensive capabilities for creating, configuring, and managing network objects, such as segments, gateways, and firewall rules, directly from code.

VMware HCX (Hybrid Cloud Extension) is designed to simplify application migration, workload rebalancing, and business continuity across data centers and clouds. It provides services such as live migration, disaster recovery, and continuous availability.

The NSX-T feature that an administrator should use to secure Virtual Machines on the same Layer Two Segment is the Distributed Firewall. The Distributed Firewall provides micro-segmentation and east-west traffic control directly at the virtual network interface card (vNIC) level, allowing for granular security policies to be enforced within the virtual environment.
