Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 240

An engineer must repurpose a lab WLC appliance for use in the production environment of the enterprise. After the new WLC is configured with the information of the other WLC, the mobility tunnels are still not coming up. What is the reason?

Answer options

• A. A firewall is blocking UDP port 16667 between the WLCs.
• B. The WLC management interfaces are in the same VLAN.
• C. The hardware platform is incompatible.
• D. The mobility groups are different.

Correct answer: C

Explanation

The correct answer is C because if the hardware platforms of the WLCs are incompatible, the mobility tunnels will not function properly regardless of configuration. The other options could present issues, but they are not the primary reason for the mobility tunnels not coming up.
