Cisco Conducting Cisco Unified Wireless Site Survey (CUWSS) v2.0

QUESTION NO: 1
In evaluating a post-installation WLAN deployment, problems are occurring when a client roams from one AP to another. The client bounces back and forth between APs. Which three items can be checked to resolve this issue? (Choose three.)

A. Check if the roaming settings in the AP are set properly for non-CCX clients. B. When a client roams from one AP to the next, check the client RSSI and SNR levels for both APs at the roaming point. C. Simplify 802.1X/EAP by moving from external RADIUS to local authentication. D. Verify the authentication being used for the same test that the client would use under production. E. Check that the client roaming parameters are set properly. F. Check the RF levels of the first AP as the client moves toward the second AP.

Correct Answer: B,D,F

QUESTION NO: 5
Refer to the exhibit. A company requires a multi-point bridge solution with Cisco 1400 series bridges. The central bridge (B1) is set to 10 dBm, the manufacturing remote bridge (B2) is set to 20 dBm, the inventory remote bridge (B3) is set to 20 dBm, and the shop remote bridge (B4) is set to 10 dBm. What is the maximum allowed power setting for all four bridges?

A. B1=12dBmB2=24dBmB3=24dBmB4=24dBm B. B1=10dBmB2=24dBmB3=24dBmB4=24dBm C. B1=24dBmB2=12dBmB3=12dBmB4=12dBm D. B1=24dBmB2=24dBmB3=24dBmB4=24dBm E. B1=20dBmB2=20dBmB3=20dBmB4=20dBm F. B1=12dBmB2=12dBmB3=12dBmB4=12dBm

Correct Answer: A

QUESTION NO: 6
An engineer is conducting a site survey for use of Cisco 7925 wireless clients. Which two design criteria are necessary to ensure proper network design? (Choose two.)

A. -65 dBm RSSI or better B. 25 percent overlap C. -72 dBm RSSI or better D. 20 percent overlap E. -67 dBm RSSI or better F. 15 percent overlap

Correct Answer: D,E

QUESTION NO: 7
When performing a post-installation audit using the Ekahau Survey tool, which four steps are associated with the passive portion of the audit? (Choose four.)

A. Check that all channels are supported by the APs regardless of client capabilities. B. When you have completed the post-installation surveys, compare them to the surveys that were performed before the installation. They should look nearly identical. C. Survey by SSID to ensure that smooth roaming is taking place. D. Check to see if the signal levels on other access points that are heard on the same channel are at least 19 dBm weaker than the access point that you are next to. E. Check for co-channel interference by standing near an access point on one channel and watching for other access points that are on the same channel. F. Verify that the real-world network traffic (for example, physical data rate, packet loss, etc.) meets user requirements.

Correct Answer: A,B,D,E

QUESTION NO: 8
Refer to the exhibit. During a post Mesh deployment survey, an engineer notices frame collisions occurring when MAP-1 and MAP-3 talk to RAP-2. Which type of issue is the engineer observing?

A. co-channel interference B. hidden node C. CSMA-CA D. exposed node E. backhaul latency

Correct Answer: B

QUESTION NO: 9
Which item is more of an issue to outdoor wireless mesh deployment than indoor?

A. Reflection B. Scattering C. Absorption D. Delay spread

Correct Answer: D

QUESTION NO: 10
You have a multinational customer that would like you to perform a wireless site survey for a new manufacturing facility in Singapore. They have had a local vendor install a point-topoint wireless bridge link between two buildings 1 km apart. The ground between the buildings is flat but because facilities are in the mountains, dense fog is an issue. There are no line of sight issues between the buildings. The link is experiencing errors and throughput issues. Currently the two radios are set to operate at 2.4 GHz and the transmit power is set to 7 dBm with 7 dBm antennas. What do you need to take into consideration when performing the site survey for this link?

A. Change the radio power to 13 dBm. B. Change the radio power to 20 dBm and replace with a 16 dBm antenna. C. Change the radio power to 17 dBm. D. Change the radio power to 29 dBm.

Correct Answer: A
