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.

An enterprise is using wireless as the main network connectivity for clients. To ensure service continuity. a pair of controllers will be installed in a datacentre. An engineer is designing SSO on the pair of controllers. What needs to be included in the design to avoid having the secondary controller go into maintenance mode?

A. The Keep alive timer is too low. which causes synchronization problems.

B. The connection between the redundancy ports is missing.

C. The redundancy port must be the same subnet as the redundancy mgmt.

D. The Global Configuration of SSO is set to Disabled on the controller.

An enterprise is using two wireless controllers to support the wireless network. The data centre is located in the head office Each controller has a corporate WLAN configured with the nameCopr-NET390595865WLC-1 and CoprNET6837l638WLC-2. The APs are installed using a round-robin approach to load balance the traffic. What should be changed on the configuration to optimize roaming?

A. Move all access points to one controller and use the other as N+1 HA.

B. Move the controllers to an external data center with higher internet speeds.

C. Use the same WLAN name for the corporate network on both controllers.

D. Place the access points per floor on the same controller.
