200-901 Practice Question: Refer to the exhibit
Exhibit
Refer to the exhibit.
```
{
"hostname": "Router1",
"interfaces": [
{
"name": "GigabitEthernet0/0",
"ip": "10.1.1.1",
"mask": "255.255.255.0",
"enabled": true
},
{
"name": "GigabitEthernet0/1",
"ip": "192.168.1.1",
"mask": "255.255.255.0",
"enabled": false
}
]
}
```Refer to the exhibit. A Python script uses the Cisco IOS-XE RESTCONF API to retrieve the device configuration. The returned JSON is shown. What must be done to enable the GigabitEthernet0/1 interface using the API?
⚠ Common exam trap
Cisco often tests the distinction between PUT (full replace) and PATCH (partial update) in RESTCONF, where candidates mistakenly choose PUT thinking it can be used for single-field changes, but that would require sending the entire resource payload.
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
✓
Send a PATCH request to the interface resource with the JSON payload {"enabled": true}.
RESTCONF uses PATCH for partial updates. To enable an interface, you only need to send the specific field that changes ({"enabled": true}) to the interface resource URI, which modifies the configuration without replacing the entire resource.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Send a PATCH request to the interface resource with the JSON payload {"enabled": true}.
Why this is correct
PATCH partially updates the resource; changing enabled to true will enable the interface.
- ✗
Send a DELETE request to the interface resource.
Why it's wrong here
DELETE removes the interface, not what is needed.
- ✗
Send a GET request to the interface resource and parse the response.
Why it's wrong here
GET retrieves data but does not modify the configuration.
- ✗
Send a PUT request to the interface resource with the entire JSON payload.
Why it's wrong here
PUT replaces the entire resource; it can be used but is heavy-handed; the exhibit only requires changing one field.
