CWNA: Certified Wireless Network Administrator v109 — Question 10

What best describes WPA2 in relation to 802.11 wireless networks?

Answer options

• A. WPA2 is the second version of WPA and it enhances security through the use of TKIP instead of WEP.
• B. WPA2 is the IEEE standard that defines security for WLANs.
• C. WPA2 is a certification created by the Wi-Fi Alliance that validates devices correctly implement CCMP/AES.
• D. WPA2 is specified in the 802.11 standard as implementing CCMP/AES.

Correct answer: C

Explanation

The correct answer, C, is accurate because WPA2 is indeed a certification from the Wi-Fi Alliance that confirms devices correctly use CCMP/AES for encryption. Option A incorrectly states that WPA2 uses TKIP, which is not the case as WPA2 primarily uses CCMP/AES. Option B is misleading as WPA2 is not an IEEE standard itself, and option D, while true about its specification, does not capture the certification aspect that is vital to WPA2.
