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.

In the context of an EVPN VXLAN fabric, the Route-Reflector Persona is most appropriately configured at theServices Aggregationlayer. This layer is responsible for interconnecting different network services and typically includes more robust, higher-capacity devices capable of handling the route-reflection functions for EVPN VXLAN.

In an Aruba Networks fabric, route reflectors are used to optimize the distribution of BGP routes. The Services Aggregation layer, which is centrally located in the network topology, is best suited for this role due to its high availability and ability to efficiently manage routes between the core and access layers.

Therefore, if you were to click on the image provided, you would select the Services Aggregation layer to configure the Route-Reflector Persona.

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.

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.

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'.
