質問 57
Two cisco 5520 wireless LAN controllers are managing all access points throughout the network. The WLCs are in different locations to provide geographical redundancy a mobility group has been configured on both WLCs and has a UP status on both controllers. The Aps in location A are statically configured to use controller A as the primary and controller B as the secondary. If the WLC in location A goes offline. The Aps successfully join the WLC in location, but they do not fail over to their primary configured controller. Which configuration task fixes the issue?

A. Use DHCP Option 43 and specify WLC in location A as primary.
B. Configure the WLC in location A as primary using the CAPWAP AP Controller IP Address command on all the location A Access points.
C. Change the AP Failover Priority to critical.
D. Enable AP fallback globally on the WLC

質問 61
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 AP groups for each desired location, map the correct VLANs to the internal SSID, and add the access points for that location.
B. 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.
C. 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.
D. Create FlexConnecI groups, place the access points in. and sat the correct VLAN to SSID mapping based on location.

正解: A

質問 62
Refer to the exhibit.

A client roams between two APs that are registered to two different controllers, where each controller has an interface in the client subnet. Both controllers are running AireOS. Which scenario explains the client roaming behavior?

A. Controllers exchange mobility control messages (over UDP port 16666) and a new client session is started with the new controller.
B. Controllers exchange mobility control messages (over UDP port 16666) and the client database entry is tunneled from the original controller to the new controller.
C. Controllers exchange mobility control messages (over UDP port 16666) and the client database entry is moved from the original controller to the new controller.
D. Controllers do not exchange mobility control messages (over UDP port 16666) and the client database, entry is not moved from the original controller to the new conrtoller.
