Q11. After a wireless deployment, users report that wireless voice clients are experiencing an unacceptable amount of delay while roaming during a call on the Cisco Unified 7925 Series phones. The customer environment consists of multiple controllers, all running 7.4.121.0 code, operating in a centralized deployment. What configuration issue is most likely contributing to the problem?
A. The authentication should be set to WPA2-PSK to allow for 802.11n speeds for the Cisco Unified 7925 phones.
B. The access points on that floor are all on one controller and should be load balanced evenly across multiple controllers.
C. The access points for that floor are salt and peppered across multiple controllers and should be moved to the primary controller.
D. The wireless phones are operating in the 2 4 GHz band and should be configured for the 5 GHz band.
Answer: B
Q12. A corporation has a Cisco Unified Wireless Network that has been deployed for voice coverage. The wireless data rates have been tuned to mandatory rates of 18 Mbps and 36 Mbps. Some wireless clients have been experiencing drops streaming multicast video while moving throughout the building. What is the cause of the drop in video?
A. Clients are roaming at lower data rates and are not maintaining 36Mbps connectivity.
B. Clients are not roaming due to coverage. This is causing the multicast data to drop due to the client re-associating often.
C. Clients are connected at 18Mbps; however, other clients are connecting at 12Mbps and are causing the multicast video to degrade.
D. Clients are maintaining a 12Mbps rate and cannot receive the stream at 18Mbps.
Answer: A
Q13. Controllers WLC_1 and WLC_2 are in the same mobility group. A wireless client that does not have the same VLAN interface roams from WLC_1 to WLC_2. What happens to the client roaming?
A. The client context is deleted in controller WLC_1, and a new client context is created in WLC_2 to become the anchor controller
B. The client context is moved from controller WLC_1 to controller WLC_2. The result is that the WLC_1 client context is deleted and WLC_2 becomes the anchor controller.
C. The client context is copied from controller WLC_1 to controller WLC_2. The result is that WLC_1 becomes the foreign controller and WLC_2 becomes the anchor controller.
D. The client context is copied from controller WLC_1 to controller WLC_2. The result is that WLC_1 becomes the anchor controller and WLC_2 becomes the foreign controller.
