200-901 Practice Question: A developer is writing a Python script to…
A developer is writing a Python script to interact with a Cisco device using RESTCONF. The script sends a PUT request to modify an interface configuration. Which HTTP response code indicates that the resource was successfully created?
⚠ Common exam trap
Cisco often tests the subtle difference between 200 OK (successful operation with response body) and 201 Created (successful creation of a new resource), leading candidates to mistakenly choose 200 OK when the question explicitly asks about resource creation.

Correct answer & explanation
✓
201 Created
In RESTCONF, a successful PUT request that creates a new resource returns HTTP 201 Created. This aligns with RFC 8040, where PUT can be used for both creation and replacement; the 201 response specifically indicates the resource did not exist before and was created by the request.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
404 Not Found
Why it's wrong here
404 Not Found reports that the target URI does not exist, so the configuration was not applied at all. It is tempting when a request references an incorrect path, but here the resource was created successfully, which RESTCONF reports with 201 Created.
- ✓
201 Created
Why this is correct
A 201 Created response confirms the PUT resulted in a new resource, and RESTCONF returns it when the target datastore node did not previously exist. This satisfies the stem's requirement for the code signalling successful resource creation rather than mere modification.
- ✗
200 OK
Why it's wrong here
200 OK reports success for an existing resource being replaced or returned, not creation of a new one; RESTCONF returns 201 Created when PUT instantiates a previously absent resource. 200 is correct when PUT updates an already-existing interface configuration.
- ✗
204 No Content
Why it's wrong here
204 No Content confirms success but signals that no body is returned; it is the standard response when a PUT updates an existing resource without creating one. It is tempting because it does indicate success, yet creation is signalled by 201 Created instead.
