Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 101

A customer uses a Cisco Catalyst 9800 Series wireless controller to manage all of the APs for a campus network. Secure guest access is required for the guest network. A Cisco 5520 anchor controller is deployed within a DMZ. Which design approach ensures that the mobility tunnel is established successfully between the wireless controller and the anchor controller?

Answer options

• A. Run an Inter-Release Controller Mobility compatible software version on the wireless controller.
• B. Enable control plane encryption on the wireless controller.
• C. Disable data link encryption on the anchor controller.
• D. Run an Inter-Release Controller Mobility compatible software version on the anchor controller.

Correct answer: D

Explanation

The correct answer is D because the anchor controller must run a compatible software version to successfully establish the mobility tunnel with the wireless controller. Options A and B are irrelevant as they pertain to the wireless controller's configurations, while option C incorrectly suggests disabling encryption, which could compromise security.
