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.

8. You are connecting your access point and it is set to root. What does extended service set ID mean?
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.
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.
