Question

BlackTom AI · Accepted Answer

The question asks which items are contained in the beacon frames of a wireless/mobile network. This requires examining each option in turn and distinguishing between information typically advertised in beacon frames versus information not included.
Option 1: 'DNS server's IP address' — This is generally not advertised in beacon frames. DNS server information is more relevant to DHCP responses or IP configuration delivered after association, not part of the periodic beacon management frames. Therefore this is not contained in beacon frames.
Option 2: 'list of mobiles with AP-to-mobile frames waiting to be sent' — Beacon frames do not carry a queue or list of pending unicast or data frames destined to clients. Beacons are management frames that broadcast network presence and configuration, not per-client transmission queues. So this is incorrect.
Option 3: 'AP's name (SSID)' — The SSID is a core field in beacon frames, used by clients to identify and select the BSS to join. The beacon frames regularly advertise the network's SSID for discovery. This is a correct item that is contained in beacon frames.
Option 4: 'AP's Mac Address' — The AP's MAC address (BSSID in the beacon frame) is also included in beacon frames to identify the access point and the specific BSS. This is another correct item contained in beacon frames.
In summary, the correct contained items are the AP's name (SSID) and the AP's MAC Address, while the DNS server's IP address and the list of mobiles waiting to be sent are not included in beacon frames.
