Refer to the exhibit. A network engineer wants use API update information about device interfaces. The network devices are deployed in a Cisco DevNet Sandbox and have running interfaces. Which value i

`application/yang.data+yaml` specifies YAML as the serialization format, which, while possible, is less common for network automation APIs compared to JSON.

RESTCONF APIs, which are commonly used to interact with network devices using YANG data models, typically utilize JSON as the preferred data serialization format. The `application/yang.data+json` media type correctly indicates that the request body contains data structured according to a YANG model and formatted as JSON, making it suitable for programmatic updates.

`application/yang.data+utf8l` is not a standard or recognized media type for representing YANG data in an API context.

`application/restconf.data+txt` specifies plain text, which is not suitable for the structured data required when interacting with YANG models via RESTCONF.
