A customer has this wireless design:
* two Cisco Catalyst 9800 Series wireless controllers that are configured in a high-availability SSO cluster to manage the APs in a local office network
* 100 APs in local mode that are registered to the high-availability cluster
* one Catalyst 9800 Series wireless controller that is deployed as an anchor in a DMZ
* a CAPWAP tunnel in UP state between the high-availability cluster and the anchor WLC
The customer wants the anchored traffic to remain up if a single WLC in the high-availability cluster fails. How must this requirement be incorporated into the design?
Configure the APs with the high-availability cluster as the primary base.
Deploy EMC APs as anchors and configure a high-availability cluster.
Create a separate EoIP tunnel for each WLC in the high-availability cluster.
Configure the mobility MAC address for the high-availability cluster.
Refer to the exhibit.
A network engineer has identified that during a recent controller failure, several APs failed over to the tertiary controller instead of the secondary controller. The configuration from one of the APs is provided. Which design consideration led to the issue?
The secondary controller was at capacity.
The secondary controller is an SSO configuration.
The tertiary controller is an HA-SKU controller, so it took priority.
The tertiary controller is in the same subnet as the primary controller.
A customer has a single anchor WLC named Anchor A. Anchor A is in a DMZ and provides guest access. The customer wants to deploy an additional anchor controller named Anchor B to provide redundancy if Anchor A fails. Which design approach should be taken for the guest WLAN priority on the foreign WLC for each anchor WLC?
Set Anchor A to priority 3 and Anchor B to priority 3.
Set Anchor A to priority 3 and Anchor B to priority 1.
Set Anchor A to priority 1 and Anchor B to priority 1.
Set Anchor A to priority 1 and Anchor B to priority 3.
Refer to the exhibit.
An engineer determined that during a recent controller failure, some APs did not failover to their secondary controller based on the network design, which has sufficient licenses for all APs. The controllers are not in a mobility group but have A records for their hostnames in DNS. Which setting needs to be addressed?
The controllers must be in the same mobility group.
The secondary controller IP address is incorrect.
DNS hostnames are required to be FQDN.
The AP failover priority was not set high enough.
A wireless engineer must design mobility between two buildings at a campus site. The engineer has one controller at each site. The engineer is investigating inter-controller CAPWAP data and control traffic. Which two ports must be open? (Choose two.)

An engineer has designed an anchor redundancy for guest clients connecting to SSID with auto-anchor configured. After adding a second Anchor WLC under the SSID mobility anchor list, clients are load-balanced between existing and new anchors instead of having one anchor as active and the other one as standby. Which feature should be included in the design that will be configured on the WLC running
8.1 or above to ensure anchor redundancy?
Auto-Anchor Foreign Mapping
AP groups
Guest Anchor Priority
802.11r
An engineer is configuring a centralized set of controllers for separate facilities. Which two Cisco wireless architectures must be used to ensure flexible sizing of WLAN to VLAN mappings? (Choose two.)
interface group
mobility group
AP group
controller group
RF group
APs in a remote office recently have been converted from local mode to FlexConnect to take advantage of the local switching. After the change, remote wireless users report voice quality issues and bad quality on wireless IP phones while roaming. A debug is performed, and it is noticed that the 802.11r Fast Transition is not working as expected, like on local mode AP, though the same WLAN configuration is in place. What is the cause of the issue regarding the FlexConnect APs?
They do not support 802.11r FT.
They must be added into AP groups along with a common RF profile.
They must be in a FlexConnect group to support 802.11r FT.
They must be added to AP groups to support fast roaming methods.
An enterprise is using a Cisco AireOS controller and Wi-Fi 6 APs. The controller is installed in the head office, and the employees primarily use Apple OS devices. The APs broadcast WLAN ENT-WLAN406558520-1 for the employees and a guest WLAN with similar naming. What needs to be enabled on the controller to optimize roaming?
Aggregated Probe Response Optimization
Fast SSID Changing
Load Balancing Window
Client Timers
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?
Set AP fallback to enabled.
Set AP fallback to disabled.
Change the HA SKU secondary unit option.
Change the default mobility domain.
