Explanation

The exhibit displays a JSON data structure representing a dogbreed entry, which would typically be the representation of a resource that was successfully created on the server.

Common mistakes.

• A. A GET request is used for retrieving existing data and typically does not include a request body.
• B. CONFIG is not a standard HTTP method used in RESTCONF for data manipulation.
• C. A PUT request is used to either create a resource at a specified URI or replace an existing resource, but POST is generally preferred for adding new items to collections where the server assigns the identifier.

Concept tested. RESTCONF POST method for resource creation
