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.

2.4 GHz

3. What are three basic parameters to configure on a wireless access point?
IEEE 802.11i
Three
The three basic parameters to configure when setting up an access point are the SSID - the RF channel - and the authentication method.
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.

4. Two workers have established wireless communication directly between their wireless laptops. What type of wireless topology has been created by these employees?
Block Acknowledgments
Independent Basic Service Set (IBSS) is ad-hoc wireless
Changing the default SSID value and administrator password
WPA2 uses AES-CCMP for encryption. WPA uses TKIP.

5. 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.
IEEE 802.11i
The three basic parameters to configure when setting up an access point are the SSID - the RF channel - and the authentication method.
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.

6. What is the frequency range of IEEE 802.11b?
Block Acknowledgments
5 GHz

7. How many non-overlapping channels are available with 802.11b?

The SSID is configured incorrectly on the client.

10. Which encryption type does WPA2 use? WPA?
Changing the default SSID value and administrator password
WPA2 uses AES-CCMP for encryption. WPA uses TKIP.
PEAP - EAP-FAST - Local-EAP
Cordless phone interference - antenna type or orientation - and metal filing cabinet reflection of the RF signal can all give rise to connectivity issues.
