200-901 Software Development and Design Practice Question
Which HTTP status code indicates that a POST request successfully created a new resource?
⚠ Common exam trap
200-901 often tests the confusion between 200 OK and 201 Created, since both indicate success — candidates must remember that 201 specifically signals resource creation.

Correct answer & explanation
✓
201 Created
HTTP 201 Created is the standard response indicating that a request (typically POST) has succeeded and resulted in the creation of a new resource. The response often includes a Location header pointing to the URI of the newly created resource, per RFC 7231.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
204 No Content
Why it's wrong here
204 No Content confirms success but signals that no representation accompanies the response, so it does not indicate that a resource was created. It is tempting because 2xx codes denote successful requests, yet 204 is used for updates or deletions returning no body; creation is signalled by 201 Created.
- ✗
301 Moved Permanently
Why it's wrong here
301 Moved Permanently is a redirection status telling the client the resource now resides at a different URI, so it reports relocation rather than creation. It is tempting because 3xx responses follow a successful request, but 301 concerns URL changes; 201 Created is the code for a newly created resource.
- ✓
201 Created
Why this is correct
HTTP 201 Created is returned when a POST request results in a new resource being created on the server, typically accompanied by a Location header identifying the new resource's URI. It precisely signals successful creation, unlike 200 OK, which merely indicates general success.
- ✗
200 OK
Why it's wrong here
200 OK reports generic success and returns a representation, but does not assert that a new resource was created; it also covers retrievals and updates. It is tempting because 200 is the common success code, yet 201 Created specifically confirms creation and typically carries a Location header.
