Question

Which of the following approaches to wireless LAN (WLAN) security uses AES for encryption?

a) WEP (Wired Equivalent Privacy)
b) WPA (Wi-Fi Protected Access)
c) 802.1X
d) WPA2 (Wi-Fi Protected Access 2)

Answer 1

WPA2 (Wi-Fi Protected Access 2) is the WLAN security approach that uses AES encryption, providing a higher level of security than its predecessors WEP and WPA.

Step-by-step explanation:

The approach to wireless LAN (WLAN) security that uses AES for encryption is WPA2 (Wi-Fi Protected Access 2). While WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access) were earlier security protocols that have been found to have vulnerabilities, WPA2 is the more secure protocol that uses the Advanced Encryption Standard (AES) to ensure data confidentiality. The 802.1X is an authentication framework that provides some security for WLANs but is not itself an encryption method. Hence, WPA2 is the correct answer.
