  1. The link to the parent must offer at least 10-dBm SNR.

  2. Both APs have the same BGN.

  3. The channel to the potential preferred parent can have no interference.

  4. The link to the parent must offer at least 20-dBm SNR.

  5. The channel to the potential preferred parent is not silent or blacklisted.

  6. Both APs must use the default BGN.

Answer: B,D,E

Question No: 12

  2. greater effect on Cisco WCS CPU overhead and Cisco MSE disk utilization but not on network traffic levels and Cisco MSE CPU overhead

  3. greater effect on Cisco WCS CPU overhead and Cisco MSE CPU overhead but not on Cisco MSE disk utilization and network traffic levels

  4. greater effect on Cisco MSE disk utilization and network traffic levels but not on Cisco WCS CPU overhead and Cisco MSE CPU overhead

Answer: A

Question No: 13

What network will be connected by default when connecting to the unused Ethernet port of a MAP?

  1. the native VLAN that the MAP is connected to

  2. the VLAN associated with the SSID that the MESH APs are communicating on

  3. the VLAN associated with WLAN number 1 in the WLC

  4. the VLAN of the first SSID accessible to wireless clients of this MAP

  5. the native VLAN that the WLC is connected to

Answer: A

Question No: 14

A WLC receives a coverage hole detection alert from an AP. What two conditions must occur for the controller to dynamically mitigate the situation? (Choose two.)

  1. The AP serving the troubled client must currently have a power level 2 or lower.

  2. The client must be able to dynamically raise its power level to match the new AP power.

  3. The AP must be RF visible to additional APs on the other side of the coverage hole for calibration.

  4. The client must have WMM-PS disabled to allow for the increased power usage.

  5. The AP serving the troubled client must currently have a power level higher than 2.

Answer: A,B

Question No: 15

The primary Cisco WLC v7.0 has rebooted to a newer version of software, causing the APs to associate to the secondary controller or controllers. Given the default configuration parameters, what happens when the primary Cisco WLC is back in service?

  1. APs remain on the existing controller.

  2. APs remain on the existing controller until the APs are loaded with newer software, and then will return to the primary controller.

  3. APs return to the prior controller on a first-come, first-serve basis.

  4. APs return to the prior controller based on AP Failover Priority Level 1 first, followed by 2 through 4 ascending.

  5. APs return to the prior controller based on AP Failover Priority Level 4 first, followed by 3 through 1 descending.

Answer: C

Question No: 16

An engineer is designing a WLAN for context aware services and has to mount antennas higher than planned. What is the maximum recommended antenna mounting height for satisfactory performance?

  1. 10 feet

  2. 20 feet

  3. 30 feet

  4. 40 feet

Answer: B

Question No: 17

An engineer is receiving out-of-sync notifications in the alarm window of WCS. What should the engineer configure to ensure these alarms are addressed?

  1. disable Out of Sync Alerts as they are resolved automatically

  2. On the WCS, Check the Mobility Service Synchronization check box, choose Execute Now, and then click Go.

  3. On the MSE, check the Mobility Service Synchronization check box, choose Execute Now, and then click Go.

  4. On the WCS, edit the Mobility Service Synchronization.

Answer: D

Question No: 18

Upon boot, a Mesh AP attempts what two methods of discovering a controller? (Choose two.)

  1. If Ethernet is disconnected, it attempts to connect wirelessly using AWPP.

  2. If Ethernet is disconnected, it attempts to connect wirelessly using the configured DHCP option.

  3. If both Ethernet and wireless are available, it only attempts discovering via the Ethernet.

  4. If both Ethernet and wireless are available, it uses Ethernet first. If it cannot then it choose wireless.

  5. If only wireless is available and it is configured as a MAP, it does not attempt to connect to a WLC.

Answer: A,D

Question No: 19

Which statement describes the purpose of the Cisco WLC v7.0 AP global configuration parameter AP Primary Discover Timeout?

  1. Adjust the AP heartbeat timer to detect the primary controller.

  2. Adjust the AP timeout for missed heartbeats for the primary controller.

  3. Adjust the AP discovery timer of backup controllers.

  4. Adjust the AP boot time discovery of controllers.

Answer: C

Question No: 20

Which report category group in Cisco WCS v7.0 contains the commonly used Configuration Audit report that is used for comparing configuration differences between Cisco WCS and Cisco WLC?
