Answer: C

Explanation:

The issue described suggests that the clients are not maintaining their connection when roaming between the 5520 and 9800 controllers after a failure on the primary 5520 WLC. To remedy this, the ‘new mobility’ feature should be configured on the 5520 cluster. This feature, also known as Converged Access Mobility, allows for seamless client roaming and consistent policy enforcement across different WLC platforms, which is essential in a mixed environment of AireOS and IOS-XE controllers.
