HPE7-A07 Sample Questions Answers

The existing configuration for the WLAN ssid-profile has enabled MAC authentication which, while suitable for IoT devices that may not support 802.1X, can interfere with the normal 802.1X authentication process for other devices. By removing themac-authenticationdirective from the WLAN configuration, the non-IoT 802.1X devices should be able to connect without issues as the authentication process will not be disrupted by MAC authentication checks. This adjustment ensures that the WLAN ssid-profile is correctly aligned with the authentication requirements for both IoT and non-IoT devices within the network environment, conforming to the best practices for mixed-device WLAN configurations.

When troubleshooting a WLAN with 802.1X tunneled SSID issues, AP tunnel states indicate the status of the connection between the AP and the gateway/controller. The states 'SM_STATE_REKEYING' and 'SM_STATE_CONNECTING' could indicate transitional states where the connection has not been fully established, hence users might face issues connecting to the SSID. 'SM_STATE_REKEYING' implies that the AP is in the process of re-establishing encryption keys, while 'SM_STATE_CONNECTING' indicates that the AP is trying to establish a connection with the controller or gateway. These states could lead to temporary connectivity issues until the state transitions to 'SM_STATE_CONNECTED'.

In a packet capture from an upstream switch port mirror, you would see the VLAN assignment. The port mirror captures the traffic as it is on the network, including any VLAN tags. GRE or IPsec tunnels encapsulate the original packet, including VLAN tags, but the VLAN information is not visible within the encapsulation headers.

The exhibit shows a series of 802.1X authentication steps with multiple "Deauthentication" frames, which indicate that the client is not successfully completing the authentication process. Since the frames show repeated attempts at authentication followed by deauthentication, this suggests that the client is failing the 802.1X authentication process, which is required for network access in a WPA2/WPA3-Enterprise security environment.

In OSPF, when a router learns about an external network through both E1 and E2 advertisements, and if both have the same path cost, the router will prefer the E1 path. This is because E1 routes consider both the external cost to reach the external network and the internal cost to reach the ASBR, providing a more comprehensive metric. E2 routes only consider the external cost and ignore the internal cost to the ASBR, which could potentially lead to suboptimal routing. Therefore, the router will choose the E1 path due to its more accurate representation of the total path cost.

The correct Bandwidth Control settings for 1024 Kbps down and 2048 Kbps up for the SSID are shown in Option D. In Option D, the downstream is set at 1024 Kbps and the upstream at 2048 Kbps, both configured per user, which matches the requested configuration. This setup ensures that each user has a guaranteed bandwidth allocation of the specified rates when connected to the SSID, providing a controlled and predictable user experience.

In a VXLAN environment, unknown unicast traffic, such as ARP requests from H1, which does not have a specific destination MAC address learned by the switch A2, will be flooded out of all interfaces. This flooding behavior is necessary because A2 needs to ensure that the ARP requestreaches its intended destination, which might be on any of the interfaces. It's a part of the standard behavior of switches to handle ARP traffic when the destination hardware address is unknown.

In the United States, the operation in the 6GHz band for Wi-Fi devices such as the AP-634 and AP-635 is regulated by the Automated Frequency Coordination (AFC) system, which determines the channels that can be used based on the location. Since the Proof of Concept (POC) was conducted in a different location using AP-635 APs, the allowable channels identified by the AFC service for that location would be different than the channels allowed for the actual deployment location of the AP-634 APs. This would result in a different set of broadcasting channels being available for use in the new warehouse deployment.

The event log showing PMK (Pairwise Master Key) and OKC (Opportunistic Key Caching) key add/update and delete operations is indicative of normal client behavior in a WLAN environment. These events are part of the standard process for maintaining client session security and do not necessarily indicate any issue.

MU-MIMO (Multi-User, Multiple Input, Multiple Output) provides the most efficient use of airtime for VoIP traffic among the options listed. MU-MIMO allows multiple users to receive multiple data streams simultaneously, improving the overall efficiency of the network, especially in dense environments where VoIP applications need consistent and reliable connectivity.

Applying the 'acmethreshold' profile as shown in the exhibit would set a minimum and maximum threshold for queue 0, which affects the drop probability for traffic that exceeds these thresholds. The yellow marking indicates a medium drop precedence, so yellow-flagged traffic would be more likely to be dropped when congestion occurs, and the uplink is over-utilized. This action is intended to protect higher-priority traffic, such as VoIP, by giving it a lower probability of being dropped.

The fallback role is used as a default role in the absence of a specified role or when an authentication server is not available. Given the scenario, where the test device with MAC address 81:cd:93:13:ab:31 needs to be assigned to "iot-prod" and other devices to "iot-default", and considering there is no external authentication server configured for the test, the appropriate action would be to set a global fallback role that applies to all devices connecting to the network. This ensures that any device that does not match the specific device profile will inherit the "iot-default" role. Since the configuration for a specific MAC address (81:cd:93:xx:xx:xx) to associate with the "iot-prod" role is already in place, setting the fallback role globally accommodates the requirement for other devices.

The SSID supports 802.11ac clients, which is indicated by the "High Throughput" and "Very High Throughput" options being enabled. These are terms associated with the 802.11ac wireless standard, indicating that the SSID can serve clients that support this technology.

To achieve the bandwidth limits set by the network administrator, both per-application and total limits need to be configured. Option B shows the configuration for setting a per-application bandwidth limit, which can restrict YouTube traffic to 10 Mbps in both directions. Option D shows the configuration for setting a total bandwidth limit for all users within the voice role to 50000 Kbps (or 50 Mbps), satisfying the requirement to restrict total wireless bandwidth. By applying these configurations in HPE Aruba Networking Central, the administrator will successfully implement the necessary controls to ensure that visitor traffic does not impede the network performance for employee traffic, aligning with the capabilities of Aruba solutions to manage and prioritize network resources effectively.

Option A includes all necessary steps for a full setup of an AOS 10 mobility gateway cluster, including setting the system name, switch role, ACP FQDN address, uplink port information, IP address and default gateway, DNS IP address, controller country code, timezone and clock, andadmin password. Since the gateways must have static IP addresses and can only communicate on port 443 for a specific URL, this configuration would need to allow for static IP configuration and restrict communication to the required URL.

The correct address for the ClearPass Guest should match the FQDN of the HTTPS certificate installed on the device, which is often the FQDN of the vendor's product. This ensures secureand proper redirection to the captive portal during the authentication process. The FQDN should be entered in the Address field for ClearPass Guest configuration.
