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. Name three EAP types that allow us to use wireless LANs in enterprise networks?
The SSID is configured incorrectly on the client.
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.
PEAP - EAP-FAST - Local-EAP
Overlapping the wireless cell coverage by at least 10%

2. You are connecting your access point and it is set to root. What does extended service set ID mean?
54 Mbps
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.
5 GHz
SSID

3. What is the maximum data rate of IEE 902.11b?
11Mbps
54Mpbs
IEEE 802.11i
Cordless phone interference - antenna type or orientation - and metal filing cabinet reflection of the RF signal can all give rise to connectivity issues.

4. Which two features did WPA add to address the inherent weaknesses found in WEP?
Three
IEEE 802.11i
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.
