Question

Refer to the exhibit. What does the response "204 No Content" mean for the REST API request? - Exhibit: What Does HTTP 204 No Content Indicate for a Cisco REST DELETE

Exhibit: What Does HTTP 204 No Content Indicate for a Cisco REST DELETE

Interface loopback 100 is removed from the configuration. Correct Answer
Interface loopback 100 is not removed from the configuration.
Interface loopback 100 is not found in the configuration.
The DELETE method is not supported.

Key Takeaways

The question tests whether candidates recognize that 204 is the universal HTTP standard for successful resource deletion, distinguishing it from error states like 404 Not Found.

This question validates understanding of standard HTTP status codes within Cisco IOS XE REST APIs, confirming that a 204 No Content response signifies a successful DELETE operation without returning a response payload.

Common mistake: Candidates frequently select Option C (not found) because they misinterpret the phrase "No Content" as indicating a missing resource, confusing the 204 status code with the 404 Not Found error.

Expert Analysis

The HTTP 204 No Content status code is a standardized response defined in [RFC 9110](https://datatracker.ietf.org/doc/html/rfc9110#name-204-no-content) indicating that the server has successfully fulfilled the request and intentionally returns no payload. In the context of Cisco IOS XE and enterprise networking automation, this code is consistently paired with the DELETE method when a configuration object is successfully removed.

When you issue a REST API DELETE request targeting a specific resource path (e.g., /api/config/interfaces/loopback/100), the device parses the request, executes the removal operation, and sends back a 204 status line with an empty response body. This matches Option A, as the absence of content directly correlates to the successful deletion of the specified interface configuration. Community comments correctly reinforce that 204 is the industry-standard acknowledgment for successful deletions, and Cisco’s RESTCONF implementations adhere strictly to these REST principles.

Why the Other Options Are Incorrect

Option B implies the deletion failed or was rejected. A failed delete would typically return a 409 Conflict, 422 Unprocessable Entity, or 500 Internal Server Error.
Option C confuses 204 with 404 Not Found. While both involve "no content," 404 explicitly means the target URI does not exist on the server, whereas 204 confirms the target existed and was successfully acted upon.
Option D would trigger a 405 Method Not Allowed response, which occurs when the server recognizes the URI but does not support the requested HTTP verb.

Exam Strategy

Always anchor your REST API questions to standard HTTP status code semantics before looking for vendor-specific exceptions. Memorize that 201 Created follows successful POST/PUT, 204 No Content follows successful DELETE, and 4xx codes indicate client errors while 5xx indicate server failures.

A! 204 (200 http code generally) means successful

A 204 status code is used when the server successfully processes the request, but there is no content to return to the client. This is typically used for requests where the client wants to indicate that it has finished processing a request, such as a DELETE request
