• Question 164:

  A customer celled with a requirement that internal clients must be on different subnets depending on the building they are in, AH access points are operating in local mode and will not be modified, and this is a single controller solution. Which design approach creates the desired result?

  A. Create an SSID, place it to the desired VLAN under WLANs, and configure 802 lx in ISE to assign the correct VLAN based on the SSID from which the client is authenticating.

  B. Create FlexConnecI groups, place the access points in. and sat the correct VLAN to SSID mapping based on location.

  C. Create AP groups for each desired location, map the correct VLANs to the internal SSID, and add the access points for that location.

  D. Create mobility anchors for the SSID, and on the controller under the internal SSID. create a foreign map to the desired VLAN based on location.

  Correct Answer: C

• Question 165:

  A customer has two Cisco 550B WLCs that manage all the access points in their network and provide N+1 redundancy and load balancing. The primary Cisco WLC has 60 licenses and the secondary Cisco WLC has 40. The customer wants

  to convert the N+1 model to an HA model and provide SSO. Configuration must be performed during a maintenance window. After performing all the configurations on both controllers, the config redundancy unit secondary command is issued

  on the secondary Cisco WLC and it fails.

  Which parameter needs to be in place to complete the configuration?

  A. A cable in the RP port

  B. The secondary Cisco WLC needs a minimum of 50 base licenses

  C. The primary Cisco WLC is already set as the secondary unit.

  D. SSO needs to be enabled

  Correct Answer: B

• Question 166:

  Multiple WLCs are implemented in a high-availability configuration in a mobility group. APs are deployed with only a primary controller assigned. By default, which mobility group member controller do the orphaned APs join in the event of a failed controller?

  A. controller with the most available AP free license capacity

  B. controller with the lowest percent of associated APs per license capacity

  C. controller with the least CPU utilization over the last reporting period

  D. controller with the least number of associated APs

  Correct Answer: A
