A customer called with a requirement that internal clients must be on different subnets depending on the building they are in. All 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 802.1x in ISE to 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 to SSID mapping based on 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.

Refer to the exhibit.

An enterprise has offices spread around the globe. The APs are connected to different controllers installed in separate datacenters. The IT team wants to allow clients to roam from controllers in group ABC to controllers in group XYZ. Which feature must be incorporated in the design to accomplish this task?

A. switch peer group

B. workgroup bridge

C. mDNS gateway

D. mobility lists

An engineer is performing an active survey of a network that must support different types of mobile devices. The devices must be able to run an application that requires a minimum RF of -73 dBm. Which mobile device must be used for the survey?

A. one that has a receiver sensitivity of -70 dBm

B. one that has the lowest receiver sensitivity

C. one that has the most updated wireless card

D. one that has 802.11a wireless support

An engineer must identify the network requirements for a company that has a main office and 10 branch offices. The network must be able to support data, voice, video, and location tracking. Which two factors must be considered? (Choose two.)

A. security policy of the company for building access

B. number of wireless devices that require access

C. type of site for which the survey will be performed

D. available power sockets in the IT room

E. business type of the company

An engineer created a design where the HQ has a Cisco 5520 Wireless LAN Controller with 2000 APs associated to it. If a controller at one of the remote sites fails, the APs at that site fall back to a central controller. Global AP Failover Priority must be enabled. Which design approach must be taken to prevent the critical APs at HQ from going down and still allow APs to failover to the HQ controller?

A. Set all the APs at HQ to a failover priority of "high" and set the remote site APs to "normal".

B. Set all the APs at HQ to a failover priority of "medium" and set the remote site APs to "high".

C. Ensure that the critical APs at HQ have a failover priority of "critical", leave the rest of the HQ APs at "medium", and set the remote site APs to "high".

D. Create an access list on the HQ router that blocks CAPWAP discovery on UDP port 5246 so that the remote APs cannot kick off the APs at HQ.
