Certified Ethical Hacker (CEH v11) — Question 95

A new wireless client is configured to join a 802.11 network. This client uses the same hardware and software as many of the other clients on the network. The client can see the network, but cannot connect. A wireless packet sniffer shows that the Wireless Access Point (WAP) is not responding to the association requests being sent by the wireless client. What is a possible source of this problem?

Answer options

• A. The WAP does not recognize the client's MAC address
• B. The client cannot see the SSID of the wireless network
• C. Client is configured for the wrong channel
• D. The wireless client is not configured to use DHCP

Correct answer: A

Explanation

The correct answer is A because if the WAP does not recognize the client's MAC address, it will not allow the client to associate with the network. The other options are incorrect as the client is able to see the network (B), the problem does not mention anything about channel settings (C), and the issue is not related to DHCP configuration (D) since it pertains to the association process.
