Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Which encryption type does WPA2 use? WPA?
11Mbps
WPA2 uses AES-CCMP for encryption. WPA uses TKIP.
Three
54 Mbps
2. Describes the wireless security standard that WPA defines?
Three
The SSID is configured incorrectly on the client.
Overlapping the wireless cell coverage by at least 10%
WPA - although using the same RC4 encryption that WEP uses - provides enhancements to the WEP protocol by using dynamic keys that change constantly - as well as providing a Pre-Shared Key method of authentication.
3. Which IEEE committee has been sanctioned by WPA and is called WPA2?
RADIUS Server
IEEE 802.11i
WPA2 uses AES-CCMP for encryption. WPA uses TKIP.

10. Name three EAP types that allow us to use wireless LANs in enterprise networks?
PEAP - EAP-FAST - Local-EAP
The three basic parameters to configure when setting up an access point are the SSID - the RF channel - and the authentication method.
