The correct answer is D. Interface loopback 100 is removed from the configuration.

In REST-based APIs, the HTTP status code 204 No Content means that the request was successfully processed, but the server does not return a message body in the response. For a DELETE operation, this indicates that the targeted resource was deleted successfully. Cisco RESTCONF examples use standard HTTP response behavior, where successful DELETE requests can return 204 No Content to confirm that the configuration item was removed.

The exhibit shows a DELETE request for interface Loopback100. A 204 No Content response means:

the request was accepted,

the operation succeeded,

and there is no response payload to return.

Therefore, Loopback100 has been removed from the configuration.

A. Interface loopback 100 is not found in the configuration. If the resource were not found, the server would typically return 404 Not Found, not 204.

B. Interface loopback 100 is not removed from the configuration. This is the opposite of what a successful 204 DELETE response means.

C. The DELETE method is not supported. If DELETE were not supported, the expected response would typically be 405 Method Not Allowed, not 204.

ENCOR exam point:

For Cisco automation and RESTCONF questions, remember these common HTTP meanings:

200 OK = successful request with content

201 Created = resource created

204 No Content = successful request with no response body, often seen with DELETE

404 Not Found = resource does not exist

405 Method Not Allowed = method not supported
