A. B. C. D.A.
In an 802.11 wireless local area network (WLAN), the Basic Service Set (BSS) is the fundamental building block of the network. A BSS consists of one or more stations (devices) and an access point (AP), which acts as a bridge between the wireless and wired network.
The Layer 2 identifier of a BSS is known as the Basic Service Set Identifier (BSSID). Each BSSID is a unique identifier that consists of a six-byte MAC address. The MAC address of the radio of the access point is typically used as the BSSID.
Therefore, the correct answer to this question is A. BSSID. The BSSID is used by wireless clients to identify the specific access point to which they should connect. The BSSID is also used by wireless controllers and other management tools to monitor and manage the WLAN.
The SSID (Service Set Identifier) is a name assigned to a wireless network, and it is used by wireless clients to identify and connect to the network. The VBSSID (Virtual Basic Service Set Identifier) and MBSSID (Multiple Basic Service Set Identifier) are advanced features of some WLAN systems that allow multiple BSSIDs to be associated with a single access point.
