Which open standard defines the combination of Extensible Authentication Protocol with Advanced Encryption Standard for providing strong wireless
LAN client security?
A. IEEE 802.1X
B. IEEE 802.11i
C. WEP
D. WPA
E. WPA2
Correct Answer: B
Explanation/Reference:
Explanation:
802.11i supersedes the previous security specification, Wired Equivalent Privacy (WEP), which was shown to have security vulnerabilities. Wi-Fi Protected Access (WPA) had previously been introduced by the Wi-Fi Alliance as an intermediate solution to WEP insecurities. WPA implemented a subset of a draft of 802.11i. The Wi-Fi Alliance refers to their approved, interoperable implementation of the full 802.11i as WPA2, also called RSN (Robust Security Network). 802.11i makes use of the Advanced Encryption Standard (AES) block cipher, whereas WEP and WPA use the RC4 stream cipher. http://en.wikipedia.org/wiki/IEEE_802.11i-2004
