CCNA Wireless Questions

Instructions:

Answer 25 questions in 15 minutes.
If you are not ready to take this test, you can study here.
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.

The three basic parameters to configure when setting up an access point are the SSID - the RF channel - and the authentication method.
Extended service set ID means that you have more than one access point and they all are set to the same SSID and all are connected together in the same VLAN or distribution system so users can roam.

7. What is the frequency range of IEEE 802.11g?
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.
2.4 GHz
54 Mbps
RADIUS Server

8. Which feature of 802.11n provides MAC efficiency?
Changing the default SSID value and administrator password
RC4 algorithm
Cordless phone interference - antenna type or orientation - and metal filing cabinet reflection of the RF signal can all give rise to connectivity issues.

9. A wireless client cannot connect to an 802.11b/g BSS with a b/g wireless card. The client section of the access point does not list any active WLAN clients. What is a possible reason for this?
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.
AES-CCMP
SSID
