Exam 200-355 Question id=2304 802.11 Technology Fundamentals

In a typical wireless network using WPA, WPA2 or VPN, why is it still possible for a rogue client to launch a DOS attack?

A. WPA and WPA2 are not considered strong encryption algorithms and are easily cracked.
B. 802.11 management frames are easily compromised.
C. Cisco Compatible Extensions v5 are required with WPA, WPA2, or VPN to keep rogues from launching attacks in the wireless network.
D. The message integrity check frames are never encrypted or authenticated, which allows rogues to spoof clients.

A different receiver is needed for each 802.11a, b, g, and n radios, so using all simultaneously would severely impact the overall battery life of a mobile device.
