Question 1

Which limitation applies to the use of the Cisco WLAN Solution Management over Wireless feature?

A. Controllers must be managed using only secure protocols (that is, SSH and HTTPS), not non secure protocols (that is, HTTP and Telnet).
B. Read-write access is not available; only read-only access is supported.
C. Uploads and downloads from the controller are not allowed.
D. Wireless clients can manage other controllers however not the same controller and AP to which the client is associated.

 

Answer: C

Question 2

What is the main advantage to using a short-range ZigBee communication device?

A. Low-power, long battery-life and secure networking
B. It will replace Bluetooth devices
C. The battery is smaller than other devices
D. Its almost as cheap as Bluetooth to operate

 

Answer: A

Explanation

The ZigBee website says: “ZigBee was created to address the market need for a cost-effective, standards-based wireless networking solution that supports low data-rates, low-power consumption, security, and reliability”.

The ZigBee data rate is low (20, 40, and 250 kb/s); compared to Bluetooth (which is up to 2.1 Mb/s).

Question 3

Study the exhibit carefully (click exhibit). You are deploying a site survey for a new implementation and see this information in Cisco Spectrum Expert. Which option is true?

A. The capture shows radar. It is most probably military radar because of the frequency hopping in the “Swept Spectrogram.” The workaround is to disable DFS on the AP.
B. There is general background noise of -70dBm, which is not an issue at all for an 802.11b/g deployment.
C. The location of this capture is most likely near a kitchen, because it is clear that there is a microwave oven disrupting channel 1-13. There will be some packet loss while cooking, which is not a problem, because employees will not be working during lunch time.
D. This is a typical Bluetooth pattern. The source needs to be identified and eliminated because it will affect an 802.11b/g deployment.

 

Answer: D
