200-901 Practice Question: An automation tool uses RESTCONF to configure a…
An automation tool uses RESTCONF to configure a Cisco device. The device returns a 404 error for a PUT request. What does this indicate?
⚠ Common exam trap
Cisco often tests the distinction between HTTP status codes in RESTCONF/NETCONF contexts, and the trap here is that candidates confuse 404 (resource not found) with 400 (bad request) or 401 (authentication failure), especially when the PUT request seems syntactically correct but targets a non-existent resource.

Correct answer & explanation
✓
The resource does not exist
A 404 (Not Found) response to a RESTCONF PUT request indicates that the target resource (e.g., a specific YANG data node or URI) does not exist on the device. RESTCONF uses HTTP methods to manipulate resources identified by URIs; a PUT request is intended to create or replace a resource at that URI, but if the resource path is invalid or the data model node is not present, the server returns 404. This is consistent with RFC 8040, which defines the RESTCONF protocol.
