The Change of Authorization (CoA) messages are used in network access control scenarios and are typically received by the network access server, in this case, an Aruba AOS 10 Gateway. The correct command to verify the receipt of a CoA message is related to the control path traffic because CoA is a control plane function.

Option B,packet-capture controlpath udp 3799, is the correct answer because it specifies capturing control plane traffic on UDP port 3799, which is the standard port for CoA messages.

Options A, C, and D are incorrect because:

• Option A captures data plane traffic, not control plane traffic.
• Option C'spacket-capture interprocess udp 3799does not refer to a standard command for capturing CoA messages.
• Option D,tcpdump host-port 3799, does not specify the correct syntax for capturing traffic on Aruba devices.

Including the root and intermediate certificates in the captive portal certificate for the gateway will resolve the error seen during the login action after successful registration. This is necessary to ensure the SSL/TLS handshake can be completed successfully, as the client browser needs to validate the entire certificate chain.

When onboarding devices into a centralized management system, each device can have its individual admin password set during the onboarding process. If this password doesn't match what is expected at the group level in the central management platform, login issues such as the one described can occur.

HPE Aruba Networking Central can identify which switch port a rogue AP is connected to by using the switch's MAC address table. The MAC address table contains the associations between MAC addresses and the switch ports to which devices (including APs) are connected. When Aruba Central detects a rogue AP, it can look up the MAC address of the rogue AP in the switch's MAC address table to find the specific switch port it is connected to. This enables network administrators to quickly locate and address the rogue AP issue.

The wireless connection phase that has just been completed is L2 authentication and encryption. This phase includes processes such as the Extensible Authentication Protocol (EAP) exchange, RADIUS requests and responses, and the 4-way handshake which is characteristic of WPA2-AES encryption.

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.

The issue indicated by the output is an invalid pre-shared key (PSK). The logs show multiple failures during the WPA2 key exchange process, which points to a mismatch between the PSK configured on the client device and the PSK expected by the AOS 10 mobility gateway.

When cluster preemption is not enabled, access points (APs) will not automatically fail back to the primary gateway cluster once it is up again after having failed over to the secondary. This would result in an equal split of APs across primary and secondary clusters if both clusters are operational. Without preemption, there's no automatic rebalancing of APs back to the primary cluster, leading to the current distribution.

The configuration shown in Option A is a valid configuration for a multi-chassis link aggregation (MC-LAG) setup. It specifies the use of LACP (Link Aggregation Control Protocol) with a fast rate of LACP PDUs exchange, which is appropriate for creating a resilient and high-throughput link aggregation. The 'vlan trunk allowed all' command allows all VLANs across the trunk, and 'vlan trunk native 100' sets VLAN 100 as the native VLAN for untagged traffic.

In OSPF, the "EXSTART/DR" state indicates that the routers are trying to establish an adjacency but are unable to progress. This can happen if the OSPF network type is incorrectly configured for the type of connection between the routers. Given that R1 and R2 are connected via a point-to-point link (as suggested by the /31 subnet), setting the network type to point-to-point on both routers will remove the need for DR/BDR election, which is unnecessary on a point-to-point link, and allow OSPF to progress past the "EXSTART" state and form a full adjacency.
