| 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.
