Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 74

An enterprise is using the wireless network as the main network connection for corporate users and guests. To ensure wireless network availability, two standalone controllers are installed in the head office. APs are connected to the controllers using a round-robin approach to load balance the traffic. After a power cut, the wireless clients disconnect while roaming. An engineer tried eping from the controller but fails. Which protocol needs to be allowed between the networks that the controllers are installed?

Answer options

Correct answer: D

Explanation

The correct answer is D, IP Protocol 97, which is necessary for communication between the controllers and the access points. The other options (67, 77, and 87) do not pertain to the protocols required for maintaining the connectivity of wireless clients during roaming, and therefore would not solve the issue at hand.
