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 device must be on your wired network when running an enterprise EAP solution?
RADIUS Server
Cordless phone interference - antenna type or orientation - and metal filing cabinet reflection of the RF signal can all give rise to connectivity issues.
Changing the default SSID value and administrator password
Three

2. Which two features did WPA add to address the inherent weaknesses found in WEP?
1. Key mixing using temporal keys. 2. Per frame sequence counter. WPA uses Temporal Key Integrity Protocol (TKIP) - which includes both broadcast key rotation (dynamic keys that change) and sequencing of frames.
The three basic parameters to configure when setting up an access point are the SSID - the RF channel - and the authentication method.
