This certainly could be the answer, but so could other answers. WHat I don't see is, how do we know it's using 802.1X? It isn't stated or hinted at in the question. (Or did I miss something)

the question states that they are using 802.11 but the user cannot access the network as if NAC is not implemented. I believe GSEC recommended 802.1x due to this very nature. with NAC you can address the mac address issue.

Selected Answer: A

A possible source of the problem could be that the Wireless Access Point (WAP) does not recognize the client's MAC address. MAC address filtering is a security feature commonly used in wireless networks to restrict access based on the MAC addresses of devices. If the WAP's MAC address filtering is enabled and the client's MAC address is not added to the list of allowed addresses, the WAP will not respond to the client's association requests.

P.2283 step 1 The attacker sniffs the victim’s wireless parameters (MAC address, ESSID/BSSID, and number of channelsstep) step2 The attacker sends a DEAUTH request to the victim with a spoofed source address of the victim’s AP step 3 On receiving the request, the victim’s computer is de-authenticated and starts to search all channels for a new valid AP thus, A is correct
