When an API returns a 400 Bad Request status code, what might the response body contain?

A description of the error or invalid parameters

A network admin is writing a script to upload a configuration file to a device via REST API. The response includes the header 'Location: /api/config/123' and status code 201. What is the most appropriate use of the Location header?

Ignore it because it is only relevant for redirects.

Use it to retrieve the newly created resource in subsequent requests.

Use it as the URL for the next upload.

Use it to authenticate future requests.

A network automation engineer is designing a script that must handle both synchronous and asynchronous API operations. The API returns 200 OK for synchronous operations and 202 Accepted for asynchronous ones. The script needs to determine whether to wait for completion. What is the best approach?

Treat 202 as an error and retry the request.

Always poll the status endpoint regardless of the status code.

Check the status code: if 202, poll the status endpoint until completion; if 200, process the body directly.

Treat both 200 and 202 as success and process the body immediately.

What is the primary role of the body in an HTTP response?

To indicate the HTTP version used

To provide metadata about the response

To carry the requested data or error details

To specify the status code of the response
