A network engineer is configuring CAC on a WLC. If CAC is configured with 85% of the total radio bandwidth on a 5-GHz radio, how many clients can be accommodated?
Answer : D
Which option will allow the maximum 2.4 GHz channel usage for a survey and voice deployment in the ETSI domain?
Answer : A
A network engineer wants the DSCP marking to align with the 802.11e access category video. What will this marking be?
Answer : A
A customer is deploying a mesh outdoor wireless network based on FCC standards where spectrum analysis shows significant radar energy propagating throughout the coverage area from a local weather station. Which channel must be excluded from the access points
RRM calculation to avoid network disruption due to weather radar activity?
Answer : A
Explanation:
Weather radars operate within the 5600- to 5650-MHz band, which means that channels
124 and 128 might be affected, but also channels 120 and 132 might suffer from weather radar activity.

When designing a WLAN, AP placement is important. Which option describes how to rank the density of APs needed to support location services versus data and voice services?
Answer : A
An engineer is tuning RRM parameters to improve client connectivity. Which channel band results in the best 802.11n client compatibility?
Answer : E
Explanation:
802.11n operates on the same channel as 802.11a. For better compatibility with 802.11n clients, it is recommended to stay on lower channels (UNII-1 band).

Given an AP that can transmit at 100 mW and the client at 40 mW, which power setting should be used for a site survey?
Answer : B
After enabling global multicast, multicast traffic has been flooding the wired and wireless network. The wireless engineer has been troubleshooting and is attempting to find the source of the traffic. What command will display the multicast traffic source as well as the incoming interface?
Answer : A
What is a common cause for signal attenuation?
Answer : C
A downstream packet that contains a DSCP value arrives at the WLC Ethernet interface from the wired source network. The WLC is configured for QoS WLAN 802.1p mapping.
How does the WLC treat the CAPWAP QoS marking when leaving the controller interface for the respective AP and final wireless client destination?
Answer : B
A customer has deployed an N+N redundant wireless infrastructure. In this deployment, the access points have been salt and peppered between controllers. What configuration would be necessary to cut down on the use of mobility tunnels for voice clients?
Answer : D
An engineer must design wireless coverage in thick-walled stairwells. Which information should the engineer refer to when determining where APs can be installed?
Answer : D
A customer is deploying a Greenfield 802.11ac network on a floor that will support approximately 300 wireless devices. Which setting needs to be changed on Prime
Infrastructure Planning Tool in order to predict the amount of access points the customer needs to service the new floor?
