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. What are three basic parameters to configure on a wireless access point?
2.4 GHz
The SSID is configured incorrectly on the client.
The three basic parameters to configure when setting up an access point are the SSID - the RF channel - and the authentication method.
11Mbps

3. The TKIP encryption is based on the...
54 Mbps
RC4 algorithm
5 GHz
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.
