Options:

A.

WLC port groups

B.

Question 11

During a wireless design all APs are mapped to designated controllers in case of a failure. The controllers are located in the same data center but in different racks. An AP failed over to a controller that was not defined on its High Availability tab. The customer does not want the AP to move back to its defined Cisco WLCs until they manually intervene. What needs to be addressed in the design?

Options:

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.

Question 12

A company has 10 access point licenses available on their backup Cisco WLC and their primary Cisco WLC is at full capacity, 5 access points are set to high failover priority and 7 access points are set to critical failover priority. During a failure, not all critical access points failed over to the backup Cisco WLC. Which configuration

is the cause of this issue?

Options:

A.

The high priority access point is oversubscribed.

B.

network ap-priority is set to enable.

C.

The critical priority access point count is oversubscribed.

D.

network ap-priority is set to disable.

Question 13

An engineer must configure the virtual IP address on multiple controllers in a mobility group. Which rule must the engineer follows to ensure proper roaming?

Options:

A.

Ensure that the DNS entry is tied to the virtual IP address of the WLC.

B.

Use a unique IP address for each WLC.

C.

Ensure that the DNS Host Name field is defined.

D.

Use the same IP address for each WLC.

Question 14

A wireless deployment in a high-density environment is being used by vendors to process credit card payment transactions via handheld mobile scanners. The scanners are having problems roaming between access points in the environment. Which feature on the wireless controller should have been incorporated in the design?

Options:

A.

RX SOP

B.

802.11w

C.

AP Heartbeat Timeout

D.

Application Visibility Control

Question 15

How does AP failover priority for access points function when configured with priority 1 or 4?

Options:

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 16

Which statement about the 9800 Series Wireless Controller mobility tunnel on a Cisco Catalyst 9800 controller is true?

Options:

A.

It is an IPsec tunnel with control path only.

B.

It is a CAPWAP tunnel with data path only.

C.

It is a CAPWAP tunnel with control path and data path.

D.

It is an IPsec tunnel with control path and data path.

Question 17

How should the concept of mobility domains and mobility groups be explained to a customer?

Options:

A.

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 constrain AP fail-over between controllers.

B.

A mobility group does not constrain the distribution of security context of a client and also does not constrain AP fail-over between controllers when the WLCs are in the same mobility domain.

C.

if WLCs are in same mobility domain, they communicate with each other. Mobility groups constrain the distribution of security context of a client and also constrain AP fail-over between controllers.

D.

If WLCs are in the same mobility domain, they communicate with each other but. if an anchor WLC ® present, it must: be in the same mobility domain for communication to be possible.
