200-901 Practice Question: Needs to automate the deployment of a new VLAN on…
A network engineer needs to automate the deployment of a new VLAN on multiple Cisco switches using RESTCONF. Which URL structure should be used to create a VLAN with ID 100?
⚠ Common exam trap
Cisco often tests the distinction between PUT and POST in RESTCONF, where candidates mistakenly use POST to create a specific resource instance (like a VLAN by ID) instead of PUT, or confuse the '/operations' RPC path with data resource manipulation.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
PUT /restconf/data/Cisco-IOS-XE-vlan:vlans/vlan=100
RESTCONF uses the HTTP PUT method to create or replace a specific data resource, and the URL path follows the YANG module structure. Here, 'Cisco-IOS-XE-vlan:vlans/vlan=100' targets the VLAN list entry with ID 100, creating it if it does not exist. This aligns with RESTCONF's resource-oriented design, where PUT on a specific data node performs a create or replace operation.
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 /restconf/data/Cisco-IOS-XE-vlan:vlans/vlan=100
Why this is correct
PUT creates or replaces the VLAN resource at the specified URI.
- ✗
POST /restconf/operations/Cisco-IOS-XE-vlan:create-vlan
Why it's wrong here
This is an RPC operation, not a data resource creation.
- ✗
POST /restconf/data/Cisco-IOS-XE-vlan:vlans/vlan=100
Why it's wrong here
POST is not used to create a specific resource; PUT is appropriate.
- ✗
PUT /restconf/config/vlan/100
Why it's wrong here
This path is not compliant with the YANG module namespace.
