CCNA: Cisco Certified Network Associate — Question 52

An engineer must configure a WLAN using the strongest encryption type for WPA2-PSK. Which cipher fulfills the configuration requirement?

Answer options

• A. WEP
• B. AES
• C. RC4
• D. TKIP

Correct answer: B

Explanation

The correct answer is B, AES, as it provides strong encryption for WPA2-PSK and is widely recommended for secure wireless networks. WEP is outdated and insecure, RC4 is also considered weak, and TKIP, while better than WEP, does not offer the same level of security as AES.
