CompTIA Security+ Question J-18

A network administrator has been tasked with securing the WLAN. Which of the following cryptographic products would be used to provide the MOST secure environment for the WLAN?

A. WPA2 CCMP
B. WPA
C. WPA with MAC filtering
D. WPA2 TKIP

Answer: A

Explanation:
CCMP is the standard encryption protocol for use with the WPA2 standard and is much more secure than the WEP protocol and TKIP protocol of WPA. CCMP provides the following security services: Data confidentiality; ensures only authorized parties can access the information Authentication; provides proof of genuineness of the user Access control in conjunction with layer management

Because CCMP is a block cipher mode using a 128-bit key, it is secure against attacks to the 264 steps of operation.
