An access point has been configured for AES encryption but a client is unable to connect to it. Which of the following should be configured on the client to fix this issue?

The correct answer is B. CCMP. AES (Advanced Encryption Standard) is the encryption cipher used in WPA2.

Explanation

AES (Advanced Encryption Standard) is the encryption cipher used in WPA2. CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) is the full encryption protocol in WPA2 that wraps AES. When an access point is configured for AES, the client must be configured to use CCMP - they are effectively the same requirement. WEP and RC4 are outdated and incompatible with AES-based networks. TKIP is the older protocol used with WPA (not WPA2) and uses RC4, not AES. Configuring CCMP on the client matches the AP's encryption protocol and resolves the connection issue.
