Question # 6

A customer asks an engineer to explain the concept of mobility domains and mobilitygroups. Which statement does the engineer respond with?

A. A mobility group does not constrain the distribution of security context of a client andalso does not constrain AP fail-over between controllers when the WLC are in the samemobility domain. 
B. If WLCs are in the same mobility domain, they communicate with each other but, if ananchor WLC is present it must be in the same mobility domain for communication to bepossible.

Question # 9

A customer called with a requirement that internal clients must be on different subnetsdepending on the building they are in. All access points are operating in local mode and willnot be modified, and this is a single controller solution. Which design approach creates thedesired result?

A. Create AP groups for each desired location, map the correct VLANs to the internalSSID, and add the access points for that location.
B. Create an SSID place it to the desired VLAN under WLANs and configure 802.1x in ISEto assign the correct VLAN based on the SSID from which the client is authenticating
C. Create FlexConnect groups, place the access points in, and set the correct VLAN toSSID mapping based on location. 
D. Create mobility anchors for the SSID and on the controller under the internal SSIDcreate a foreign map to the desired VLAN based on location.

Question # 12

A customer has two Cisco wireless controllers named WLC-A and WLC-B. Each controlleris in a different building on a campus.

Question # 20

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