Certified Ethical Hacker (CEH v10) — Question 90

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 respond to association requests, preventing the client from connecting. Option B is incorrect as the client can see the network, meaning it can detect the SSID. Option C is wrong because if the client is on the wrong channel, it would not see the network at all. Option D is not applicable since the client is not connecting due to the WAP's lack of response, not because of DHCP configuration.
