Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
200 OK
Why it's wrong here
200 OK returns a representation of the result but does not assert that a new resource was created. The stem asks specifically for creation confirmation, which 201 Created conveys alongside the Location header. 200 fits a successful GET or an update returning the modified entity.
- ✗
400 Bad Request
Why it's wrong here
400 indicates the server rejected the request because its syntax or parameters were invalid, so nothing was created. A successful POST that creates a resource returns 201 Created with a Location header. 400 fits malformed JSON or a missing required field.
- ✓
201 Created
Why this is correct
201 Created signals that the POST succeeded and a new resource now exists, satisfying the stem's requirement for a creation-specific response. Unlike 200 OK, which merely confirms general success, 201 explicitly reports resource creation and typically returns a Location header pointing to the new resource's URI.
- ✗
204 No Content
Why it's wrong here
204 No Content confirms success but returns no body, and it does not assert resource creation. A POST that creates a resource returns 201 Created, typically with a Location header identifying the new URI. 204 fits a DELETE or an update needing no response payload.
