CWNA: Certified Wireless Network Administrator v108 — Question 4

What best describes WPA2 in relation to 802.11 wireless networks?

Answer options

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

Correct answer: B

Explanation

The correct answer is B because WPA2 is indeed a certification from the Wi-Fi Alliance that verifies devices implement CCMP/AES correctly. Answer A is incorrect as it describes a broader definition of WPA2, while C is wrong because WPA2 actually uses CCMP/AES instead of TKIP, and D is misleading since it implies WPA2 is only about CCMP/AES without mentioning its certification aspect.
