200-901 Understanding and Using APIs Practice Question
A developer wants to retrieve a list of network devices from Cisco DNA Center. Which HTTP method and URL structure should be used?
⚠ Common exam trap
200-901 often tests REST method semantics; candidates who associate POST with 'query' or 'search' because some APIs use POST for complex queries will incorrectly choose POST instead of GET for a simple list retrieval.

Correct answer & explanation
✓
GET /dna/intent/api/v1/network-device
To retrieve a list of network devices from Cisco DNA Center's Intent API, the correct HTTP method is GET, which is idempotent and used for read operations. The URL path /dna/intent/api/v1/network-device is the documented endpoint for listing network devices. GET requests do not modify server state, making them appropriate for retrieval.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
POST /dna/intent/api/v1/network-device
Why it's wrong here
POST submits data to create or trigger an action, so it does not return the device inventory. It is tempting because POST targets the same network-device URL and is used for operations such as creating resources or running commands, but listing devices needs GET.
- ✓
GET /dna/intent/api/v1/network-device
Why this is correct
GET requests retrieve data without modifying server state, matching the read-only intent of listing network devices. The path `/dna/intent/api/v1/network-device` is Cisco DNA Center's Intent API endpoint for device inventory, satisfying the requirement to fetch the device collection. POST, PUT or DELETE would alter resources or target the wrong operation.
- ✗
DELETE /dna/intent/api/v1/network-device
Why it's wrong here
DELETE removes a resource, so calling it on the network-device collection would attempt deletion rather than retrieval. It is tempting because DELETE targets the same collection URL and is used when decommissioning device records, but listing devices requires GET against that endpoint.
- ✗
PUT /dna/intent/api/v1/network-device
Why it's wrong here
PUT replaces or updates an existing resource, so it cannot return a device list. It is tempting because PUT uses the same network-device collection path and is valid when updating a specific device's configuration, whereas retrieval requires GET.
