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.

1. Which feature of 802.11n provides MAC efficiency?
WEP & TKIP (WPA) use RC4 WPA2 uses AES
54 Mbps
Block Acknowledgments
Cordless phone interference - antenna type or orientation - and metal filing cabinet reflection of the RF signal can all give rise to connectivity issues.

2. What device must be on your wired network when running an enterprise EAP solution?
RADIUS Server

AES-CCMP
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.

3. Describes the wireless security standard that WPA defines?
