Which two statements about deploying a mesh network by MAPs and RAPs are true on AireOS 8.0? (Choose two.)
A. The backhaul client access feature cannot be enabled on a RAP that is, a RAP does not allow clients on its 802.11a radio. This statement is true. A RAP (Root Access Point) is responsible for establishing the connection to the wired network and acts as a bridge to connect mesh access points (MAPs) to the wired network. The RAP can only provide backhaul connectivity to MAPs and cannot allow clients to connect to its 802.11a radio. The backhaul client access feature is not supported on a RAP.
C. The three main types of mesh type under the neighbor information are neighbor, parent, and child. For types default neighbor, default parent, and default child, default is used when the neighbor BGN is not known or different from the current AP BGN if the strict matching BGN feature is disabled. This statement is also true. In a mesh network, the access points (APs) are organized into a hierarchical structure. The RAP is the root node of the network, and all other access points are MAPs. The neighbor information of a MAP includes information about its neighboring APs, which can be classified as neighbor, parent, or child APs. The default neighbor, default parent, and default child types are used when the BGN (Backhaul Group Name) of the neighboring AP is unknown or different from the current AP BGN, and the strict matching BGN feature is disabled.
B, D, and E are not correct statements:
B. RADIUS and Local authentications are supported with both PCK and EAP. This statement is incorrect. AireOS 8.0 does not support PCK (Password-based Key Derivation Function) authentication. Only EAP (Extensible Authentication Protocol) authentication is supported for mesh access points.
D. A MAP/RAP must be authorized by either PSK or EAP before joining a controller in bridge mode. This statement is also incorrect. A MAP/RAP can be authorized by either PSK (Pre-Shared Key) or EAP authentication when joining a controller in local mode. However, when joining a controller in bridge mode, the MAP/RAP does not require authorization as it acts as a transparent bridge.
E. VLAN tags are always forwarded across Mesh links. This statement is incorrect. By default, VLAN tags are not forwarded across mesh links. To allow VLAN tags to be forwarded across mesh links, the VLAN tagging feature must be enabled on the mesh access points.
