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. You have finished physically installing an access point on the ceiling of your office. At a minimum - which parameter must be configured on the access point in order to allow a wireless client to operate on it?
SSID
The three basic parameters to configure when setting up an access point are the SSID - the RF channel - and the authentication method.
2.4 GHz
5 GHz

2. Which feature of 802.11n provides MAC efficiency?

Cordless phone interference - antenna type or orientation - and metal filing cabinet reflection of the RF signal can all give rise to connectivity issues.

3. Which two wireless encryption methods are based on the RC4 encryption algorithm?
11Mbps
WEP & TKIP (WPA) use RC4 WPA2 uses AES
Three
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. 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.
