What ID is typically mapped to an AP’s MAC address if a single BSS is implemented?
- A . SSID
- B . Device ID
- C . VLAN ID
- D . BSSID
D
Explanation:
The BSSID (Basic Service Set Identifier) is typically mapped to an AP’s MAC address if a single BSS is implemented. The BSSID is a unique identifier that distinguishes one BSS from another within the same RF medium. It is usually derived from the MAC address of the AP’s radio interface, but it can also be manually configured or randomly generated by some vendors. The BSSID is used by client stations to associate with an AP and to send and receive frames within a BSS.
