The correct answer is C. The data-dtls is disabled on the AireOS 5520 WLC, which causes the data path to be down. The data path being down while the control path is up indicates an issue with the data plane security configuration. The data-dtls setting on the AireOS 5520 WLC is responsible for enabling Datagram Transport Layer Security (DTLS) for the data plane, which encrypts the data…
Question
Refer to the exhibit. An engineer is about to establish a mobility peer connection between a Cisco Catalyst 9800-CL version 16.10.1e and Cisco AireOS 5520 version 8.8.120.0. The data path between the 9800-CL and AireOS 5520 is down, but its control path is up. Based on the configuration, what is the cause of the issue?
Exhibit
Options
- AThe certificate hash key is incorrect, which causes the data path to be down.
- BEncrypted mobility is being used in the 5520 configuration, which causes the data path to be
- CThe data-dtls is disabled on the AireOS 5520 WLC, which causes the data path to be down.
- DThe data-link-encryption configuration is missing from the 9800-CL configuration.

Explanation
The data path being down while the control path is up indicates an issue with the data plane security configuration. The data-dtls setting on the AireOS 5520 WLC is responsible for enabling Datagram Transport Layer Security (DTLS) for the data plane, which encrypts the data traffic between the controllers. If this setting is disabled, the data path cannot be established securely, leading to the observed issue. Therefore, enabling data-dtls on the AireOS 5520 WLC is necessary to resolve the data path downtime.
