In WLAN terminology, which statement is accurate regarding ESSID and BSSID?

• A. ESSID is the MAC address of the AP
• B. ESSID is the network name
• C. ESSID is the IP address of the gateway
• D. ESSID is the channel width

Answer: (B)

The main idea is distinguishing how a Wi‑Fi network is identified versus how a specific access point is identified. ESSID is the network name that clients see when scanning for wireless networks. BSSID, on the other hand, is the MAC address of a specific AP’s wireless interface, used to uniquely identify that particular AP within an ESSID. In practice, multiple APs can broadcast the same network name (ESSID) to support roaming, but each AP has its own BSSID. So the statement that ESSID is the network name is correct. The other options mix in details that aren’t what ESSID represents: the MAC address of the AP is the BSSID, not the ESSID; the IP address of the gateway and the channel width are unrelated to ESSID.
