A university has three campus locations and the main data center. Each campus location has a Cisco Catalyst 9800-40 WLC that manages 600 APs. The data center has a Catalyst 9800-40 WLC, which serves as N+1 backup for each campus WLC. A consulting engineer must install four additional Catalyst 9800-40 WLCs to serve as high availability SSO pairs for each campus, but only two have been approved due to budget restrictions. Requirements: Data center WLC must always be available as N+1 backup, Campus1 WLC must operate with zero downtime, and in the event of multiple campus outages, the AP priority order is to support Campus3, Campus2, then Campus1. Which design approach must the consulting engineer take?

• A. The data center WLC and Campus3 WLC are the high availability SSO pair. Campus1 APs have priority 4, Campus2 APs have priority 2, and Campus3 APs have priority 1.
• B. The data center WLC and Campus1 WLC are the high availability SSO pair. Campus1 APs have priority 4, Campus2 APs have priority 2, and Campus3 APs have priority 1.
• C. The data center WLC and Campus1 WLC are the high availability SSO pair. Campus3 APs have priority 4, Campus2 APs have priority 2, and Campus1 APs have priority 1.
• D. The data center WLC and Campus3 WLC are the high availability SSO pair. Campus3 APs have priority 4, Campus2 APs have priority 2, and Campus1 APs have priority 1.

A retail customer opened two new branch locations, and the main store HQ handles data center operations. Each branch location has three Cisco Catalyst 9130 APs. The data center has a Catalyst 9800 WLC with 18 Catalyst 9130 APs. Growing business and poor WAN uplinks cause impacted branch AP and wireless client connectivity back to HQ, and each branch location is now planned to have its own EWC controller based on C9130 AP to keep traffic local. This new design must accommodate: guests and employees sharing the same WLAN with different VLANs, guest uplink and downlink traffic restricted to 2 Mbps, and each branch acting as secondary or tertiary backup to another branch with the data center WLC always being the primary. Which design approach should the consulting engineer take?

• A. Two C9130 branch APs must be converted to EWC mode, one for the active controller and the other for standby, with HQ WLC set as a primary N+1 backup, and other branches' EWC must be added as mobility peers. The branch WLAN will use the guest anchor to HQ WLC for guest VLAN access.
• B. One C9130 branch AP must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC set as a primary N+1 backup and other branches' EWC AP as secondary and tertiary. HQ AAA must be added to EWC, and WLAN with MAB + AAA override must be configured.
• C. Two C9130 branch APs must be converted to EWC mode, one for the active controller and the other for standby, with the standby EWC set as N+1 backup. HQ AAA must be added to EWC, and WLAN with dot1x + AAA override must be configured.
• D. One C9130 branch AP must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC set as N+1 backup. The branch guest WLAN will use local web auth on guest VLAN.

An enterprise network is deploying two Cisco Catalyst 9800 WLCs in a data center to ensure uninterrupted wireless services for a campus with thousands of users. The IT management requests a design that enables seamless failover without client reauthentication or loss of connectivity if one controller fails. Ease of configuration and ongoing management are high priorities. The controllers will be connected via a high-speed LAN segment, and both must support full active-passive redundancy for all managed APs. Which design approach meets the requirements?

• A. Configure the 9800 WLCs in separate mobility groups and synchronize configurations manually.
• B. Implement SSO with redundancy management interface and AP SSO enabled between the two controllers.
• C. Deploy the controllers with VRRP to provide gateway redundancy and manually synchronize WLAN profiles.
• D. Enable N+1 redundancy, assigning primary and secondary controllers to each AP, and use DHCP for failover.

An engineer is designing guest access where guest traffic from foreign controllers on the internal network must terminate in the DMZ. Which two requirements must the design satisfy? (Choose two.)

• A. The anchor controller must be in the same Layer 2 VLAN as the foreign controller.
• B. The foreign and anchor controllers must be in the same mobility group.
• C. A mobility tunnel must exist between the foreign and anchor controllers.
• D. The guest WLAN configuration must match on the foreign and anchor controllers.
• E. The anchor controller must be the RF group leader.

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 different SSID names. The APs are installed using a round-robin approach to load balance the traffic. What should be changed in 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. Place the access points per floor on the same controller.
• D. Use the same WLAN name for the corporate network on both controllers.
