What is an MBSSID?
A . a virtual AP configured on a physical AP that share a single physical device, which is one half-duplex radio
B . a set of physical APs configured in a BSA to form cells that are controlled by a single controller
C . the group of clients that are allowed to gain access to one or more SSIDs configured in an AP
D . the identified overlap area between two cells, which identifies the clients that are operating in that area at any given time
Answer: A
Explanation:
Some APs can offer only one SSID per radio. Other APs have a slot of MAC addresses available and can support several SSIDs per radio, using Multiple BSSIDs (MBSSID). MBSSIDs basically are virtual APs that still share the same physical device, which has a half-duplex radio. MBSSIDs are a way to differentiate the traffic reaching the AP, not a way to increase the capacity of the AP.
