Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 7

An engineer has configured guest anchoring for a newly created SSID however, the mobility tunnels are not up, and EPING is failing from the foreign WLC to the anchor WLC. Which traffic flow must be allowed at the firewall to enable the communication?

Answer options

• A. UDP port 16666
• B. IP protocol 97
• C. UDP port 97
• D. TCP port 97

Correct answer: B

Explanation

The correct answer is B, as IP protocol 97 is specifically used for the mobility tunnel communication between foreign and anchor WLCs. The other options are incorrect because UDP and TCP ports 97 and 16666 do not pertain to the mobility tunnel protocol used in this scenario.
