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.
Answer: B
Explanation:
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.
