Questions 10

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?

Options:

A.  

Configure the WLC in location A as primary using the CAPWAP AP Controller IP Address command on all the location A Access points.

B.  

Use DHCP Option 43 and specify WLC in location A as primary.

C.  

Enable AP fallback globally on the WLC

D.  

Change the AP Failover Priority to critical.

B.  

Use a unique IP address for each WLC.

C.  

Ensure that the DNS Host Name field is defined.

Questions 15

APs in a remote office recently have been converted from local mode to FlexConnect to take advantage of the local switching. After the change, remote wireless users report voice quality issues and bad quality on wireless IP phones while roaming.

A.  

They do not support 802.11r FT.

B.  

They must be added into AP groups along with a common RF profile.

C.  

They must be in a FlexConnect group to support 802.11r FT.

D.  

They must be added to AP groups to support fast roaming methods.
