200-901 Practice Question: An automation script needs to update the hostname…
An automation script needs to update the hostname of a Cisco IOS-XE device via RESTCONF. Which HTTP method is appropriate?
⚠ Common exam trap
The key trap is that candidates may assume PATCH is preferred for updates, but RESTCONF's PATCH (if implemented) is for partial updates using YANG Patch, not for simple leaf replacement. For updating a single leaf like hostname, a full replacement via PUT is the standard method. Many candidates overlook that PATCH is optional and often not used in Cisco implementations.

Correct answer & explanation
✓
PUT
To update the hostname of a Cisco IOS-XE device via RESTCONF, the PUT HTTP method is appropriate because it performs a full replacement of the target resource. RESTCONF uses the YANG data model, and the hostname is a leaf node under the Cisco-IOS-XE-native YANG module. A PUT request with the complete updated hostname data replaces the existing configuration, aligning with RESTCONF's semantics for resource replacement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
PUT
Why this is correct
PUT is used to replace the target resource with the request payload.
- ✗
PATCH
Why it's wrong here
PATCH is for partial updates, but Cisco RESTCONF implementations may not support it as widely; PUT is the standard for full replacement.
- ✗
GET
Why it's wrong here

- ✗
POST
Why it's wrong here
