GSLC · Question #425
You are implementing wireless access at a defense contractor. Specifications say, you must implement the AES Encryption algorithm. Which encryption standard should you choose?
The correct answer is A. WPA 2. WPA2 is the only listed standard that mandates AES encryption via its CCMP protocol, making it the required choice for environments that specify AES.

Why each option
WPA2 is the only listed standard that mandates AES encryption via its CCMP protocol, making it the required choice for environments that specify AES.
WPA2 uses CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol), which is built on AES encryption. It replaced the weaker TKIP and RC4 algorithms used by earlier standards, making it the only choice that satisfies an AES requirement in a high-security environment like a defense contractor.
WEP uses RC4, a stream cipher that is cryptographically broken and does not use AES.
TKIP (Temporal Key Integrity Protocol) is a stopgap encryption protocol used by WPA that is based on RC4, not AES.
WPA's default encryption mode is TKIP, which uses RC4 - not AES - making it non-compliant with an AES mandate.
