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. A single 802.11g access point has been configured and installed in the center of a square-shaped office. A few wireless users are experiencing slow performance and drops while most users are operating at peak efficiency. What could likely be the caus
RADIUS Server
AES-CCMP
11Mbps
Cordless phone interference - antenna type or orientation - and metal filing cabinet reflection of the RF signal can all give rise to connectivity issues.

2. Which IEEE committee has been sanctioned by WPA and is called WPA2?
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.
IEEE 802.11i
Three
SSID

3. What is the maximum data rate of IEE 902.11b?
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.

11Mbps
Changing the default SSID value and administrator password

4. The TKIP encryption is based on the...
PEAP - EAP-FAST - Local-EAP
RC4 algorithm
RADIUS Server
WEP & TKIP (WPA) use RC4 WPA2 uses AES

5. Which feature of 802.11n provides MAC efficiency?
2.4 GHz
Block Acknowledgments
PEAP - EAP-FAST - Local-EAP
11Mbps

6. A wireless client cannot connect to an 802.11b/g BSS with a b/g wireless card. The client section of the access point does not list any active WLAN clients. What is a possible reason for this?
Changing the default SSID value and administrator password
WPA2 uses AES-CCMP for encryption. WPA uses TKIP.
The SSID is configured incorrectly on the client.
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. How many non-overlapping channels are available with 802.11b?
WEP & TKIP (WPA) use RC4 WPA2 uses AES
SSID
Three
2.4 GHz

8. What are three basic parameters to configure on a wireless access point?
54 Mbps
WEP & TKIP (WPA) use RC4 WPA2 uses AES
RC4 algorithm
The three basic parameters to configure when setting up an access point are the SSID - the RF channel - and the authentication method.

9. WPA2 uses which encryption method?
54 Mbps
AES-CCMP
54Mpbs
SSID

10. You are connecting your access point and it is set to root. What does extended service set ID mean?
IEEE 802.11i
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.
WPA2 uses AES-CCMP for encryption. WPA uses TKIP.
AES-CCMP

11. What is the frequency range of IEEE 802.11g?
2.4 GHz
54 Mbps

2.4 GHz
Changing the default SSID value and administrator password
RADIUS Server
5 GHz

13. Which wireless LAN design ensures that a mobile wireless client will not lose connectivity when moving from one access point to another?
SSID
RADIUS Server
Overlapping the wireless cell coverage by at least 10%
Three

14. What is the frequency range of IEEE 802.11a?
WEP & TKIP (WPA) use RC4 WPA2 uses AES
Overlapping the wireless cell coverage by at least 10%
The SSID is configured incorrectly on the client.
5 GHz

15. Two workers have established wireless communication directly between their wireless laptops. What type of wireless topology has been created by these employees?
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.
11Mbps
Independent Basic Service Set (IBSS) is ad-hoc wireless
RC4 algorithm

16. 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
Cordless phone interference - antenna type or orientation - and metal filing cabinet reflection of the RF signal can all give rise to connectivity issues.
