B is false because a static VXLAN tunnel does not use any protocols on the control plane, saving device resources.

Broadcast address is not an IPv6 address type. IPv6 does not support broadcast addressing, but uses multicast addressing instead. The other options are valid IPv6 address types. Unicast address identifies a single interface, multicast address identifies a group of interfaces, and anycast address identifies multiple interfaces but delivers packets to only one of them.

A mesh connection can be torn down by either of the two APs that have established it by sending a Mesh Peering Close frame to the other AP. This frame indicates that the sender no longer wants to maintain the mesh connection.

According to the Huawei documents and resources, EAP termination and EAP relay are typical 802.1X authentication modes between the access device and authentication server. In EAP termination mode, the access device terminates EAP packets and encapsulates them into RADIUS packets. In EAP relay mode, the access device directly encapsulates the received EAP packets into RADIUS using EAP over RADIUS (EAPoR) packets2. Therefore, A and B are the correct answers.

When a STA roams from AP1 to AP2 at Layer 2, AP2 notifies its neighbors of the MAC address learned from this STA. The MAC address is not encapsulated in a tunnel and sent to AP1 for forwarding. Instead, AP1 deletes the MAC address entry of the STA and releases the IP address lease.

The home agent is a device that communicates with the gateway on the STAs’ home network at Layer 3 and maintains the binding entries of STAs’ home addresses and care-of addresses. A home WAC can function as a home agent of STAs, while a home AP cannot.
