A. B. C. D.

D.

The correct answer is D: WPA2, AES.

To understand why, let's break down the options:

A. WEP is an outdated and insecure encryption protocol that is no longer recommended for use in wireless networks. TKIP is a more secure protocol but is still vulnerable to certain attacks. This combination is not considered an 802.11i RSN (Robust Security Network), which is the standard for secure wireless communication.

B. WPA2 is an 802.11i RSN and is the current standard for wireless security. However, TKIP is only an optional encryption protocol in WPA2 and is not mandatory.

C. WPA is an older wireless security standard that was replaced by WPA2. AES (Advanced Encryption Standard) is a secure encryption protocol, but it was not mandatory in WPA and is not considered an 802.11i RSN.

D. WPA2 is an 802.11i RSN and the current standard for wireless security. AES is the mandatory encryption protocol in WPA2, making this option the correct answer.

In summary, the correct answer is D because WPA2 is an 802.11i RSN and AES is the mandatory encryption protocol in WPA2.
