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.
C. If WLCs are in the same mobility domain, they communicate with each other. Mobilitygroups constrain the distribution of security context of a client and also constrain AP failover between controllers. 
D. WLCs do not need to be in the same mobility domain to communicate with each other.Mobility groups constrain the distribution of security context of a client and also constrainAP fail-over between controllers.

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. 

Answer: A

Question # 12

A customer has two Cisco wireless controllers named WLC-A and WLC-B. Each controlleris in a different building on a campus. The WLCs have different Layer 3 interfaces andbroadcast the same SSIDs from their respective APs. Users must remain connected to thesame VLAN andmaintain their IP addresses during roaming from the APs that are attached to WLC-A andWLC B. Which action accomplishes the requirement?

A. Create a mobility group between the two WLCs to allow auto-anchoring.  
B. Create an SSO cluster to ensure that client sessions sync between WLCs.  
C. Enable 802.11r on each SSID on both WLCs to allow caching of the PMK.  
D. Enable AP groups using the same name on both WLCs for each group.  

Answer: A

An AP failed overto a controller that was not defined on its High Availability tab. The customer does not wantthe AP to move back to its defined Cisco WLCs until they manually intervene. What needsto be addressed in the design? 

A. Set AP fallback to enabled.  
B. Set AP fallback to disabled.  
C. Change the HA SKU secondary unit option.  
D. Change the default mobility domain.
