220-801 Question #77: Real Exam Question with Answer & Explanation

The correct answer is A: Wireless Protected Access v2. WPA2 (Wi-Fi Protected Access 2) mandates the use of AES-based CCMP encryption and is the strongest wireless security standard listed.

Question

Which of the following wireless security standards uses AES, and is considered the MOST secure means of encryption?

Options

AWireless Protected Access v2
BTemporal Key Integrity Protocol
CWired Equivalent Privacy
DWireless Protected Access

Explanation

WPA2 (Wi-Fi Protected Access 2) mandates the use of AES-based CCMP encryption and is the strongest wireless security standard listed.

Common mistakes.

B. TKIP (Temporal Key Integrity Protocol) is an encryption protocol used with WPA (not WPA2) as a stopgap improvement over WEP; it does not use AES as its primary cipher.
C. WEP (Wired Equivalent Privacy) uses the RC4 stream cipher with short, static keys and is considered cryptographically broken and insecure.
D. WPA (Wi-Fi Protected Access) uses TKIP by default, which is weaker than AES/CCMP; it does not mandate AES as WPA2 does.

Concept tested. WPA2 AES encryption as the most secure wireless standard
