200-901 Practice Question: A developer is working with the Cisco SD-WAN…
A developer is working with the Cisco SD-WAN vManage API to monitor overlay tunnels. They need to retrieve a list of all devices with their site IDs and IP addresses. Which API endpoint is most appropriate?
⚠ Common exam trap
Cisco often tests the distinction between device inventory endpoints and monitoring/overlay-specific endpoints, leading candidates to choose 'monitor' or 'overlay' when they only need basic device information.
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
✓
GET /dataservice/device
The GET /dataservice/device endpoint returns a list of all devices managed by the Cisco SD-WAN vManage, including their site IDs and IP addresses. This is the correct endpoint for retrieving device inventory details, as it provides the necessary fields like 'deviceId', 'system-ip', and 'site-id' in the response.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
GET /dataservice/device/monitor
Why it's wrong here
The /dataservice/device/monitor endpoint returns real-time monitoring statistics such as CPU and tunnel health, not the inventory attributes (site ID, IP address) requested. It is tempting because it sounds like the monitoring endpoint, and it would be correct for retrieving live interface or control-connection counters rather than device inventory.
- ✗
GET /dataservice/device/device
Why it's wrong here
The /dataservice/device/device endpoint returns device inventory, but it does not expose the site ID attribute, which lives in the vManage device-to-site mapping. It is tempting because it lists devices and their IP addresses, and would be correct when you need hardware, model, or reachability details without site context.
- ✗
GET /dataservice/device/overlay
Why it's wrong here
GET /dataservice/device/overlay returns overlay tunnel information, not a device inventory with site IDs and IP addresses. It is tempting because overlay monitoring is the stated goal, and this endpoint would be correct when tunnel status and health, rather than device details, are required.
- ✓
GET /dataservice/device
Why this is correct
GET /dataservice/device returns the inventory of all devices managed by vManage, including site IDs and IP addresses. Other endpoints target specific device types or operational statistics, so this one satisfies the requirement to list every device with its site and address.
