CompTIA Security Plus Mock Test Q171

A security administrator wishes to increase the security of the wireless network. Which of the following BEST addresses this concern?

A. Change the encryption from TKIP-based to CCMP-based.
B. Set all nearby access points to operate on the same channel.
C. Configure the access point to use WEP instead of WPA2.
D. Enable all access points to broadcast their SSIDs.

Correct Answer: A
Section: Network Security

Explanation:
CCMP makes use of 128-bit AES encryption with a 48-bit initialization vector. This initialization vector makes cracking a bit more difficult.

Incorrect Answers:
B: Wireless APs with overlapping signals should use unique channel frequencies to reduce interference between them.
C: WEP is not a secure encryption protocol.
D: This will make the network visible, and open for attacks.
