Question # 6

An enterprise is using two wireless controllers to support the wireless network. The data centre is located in the head office Each controller has a corporate WLAN configured with the nameCopr-NET390595865WLC-1 and Copr-NET6837l638WLC-2. The APs are installed using a round-robin approach to load balance the traffic. What should be changed on the configuration to optimize roaming?

A.

Move all access points to one controller and use the other as N+1 HA.

B.

Use the same WLAN name for the corporate network on both controllers.

C.

Use the same WLAN name for the corporate network on both controllers.

D.

Place the access points per floor on the same controller.

A.

co-channel interference

B.

backhaul latency

C.

hidden node

D.

exposed node

Question # 8

Refer to the exhibit. An enterprise is using wireless as the main network connectivity for clients. To ensure service continuity. a pair of controllers will be installed in a datacentre. An engineer is designing SSO on the pair of controllers. What needs to be included in the design to avoid having the secondary controller go into maintenance mode?

A.

The Keep alive timer is too low. which causes synchronization problems.

B.

The connection between the redundancy ports is missing.

C.

The redundancy port must be the same subnet as the redundancy mgmt.

D.

The Global Configuration of SSO is set to Disabled on the controller.

Question # 9

A high-density wireless network is designed. Which Cisco WLC configuration setting must be incorporated in the design to encourage clients to use the 5 GHz spectrum?

A.

Band Select

B.

RRM

C.

Cisco Centralized Key Management

D.

load balancing

Question # 10

Which statement about AP failover priority for access points when configured with priority 1 or 4 is true?

A.

When configured with priority 1, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

B.

When configured with priority 4, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

C.

When configured with priority 4, the access point is assigned with the lowest priority level and it is marked as low. This access point fails over after other access points with the higher priority when there is primary controller failure.

D.

When configured with priority 1, the access point is assigned with the medium priority level and it is marked as medium. This access point fails over after other access points with the higher priority when there is primary controller failure.

Question # 11

A rapidly expanding company has tasked their network engineer with wirelessly connecting a new cubicle area with Cisco workgroup bridges until the wired network is complete. Each of 42 new users has a computer and VoIP phone. How many APs for workgroup bridging must be ordered to keep cost at a minimum while connecting all devices?

A.

Question # 12

A customer has multiple WLCs running N+1 redundancy with APs equally distributed. Only one WLC is a designated backup for all other WLCs so the customer must ensure that the most critical APs remain registered or get priority over other APs in case of a WLC failure. However, the customer notices on WLC failure that some critical APs remain unregistered What needs to be addressed in the design?

A.

AP fallback is not enabled on the backup WLC.

B.

AP failover priority is not enabled globally on the backup WLC.

C.

AP failover priority is not enabled globally on the failed WLC.

D.

AP fallback is not enabled on the failed WLC.

Question # 13

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.
