200-901 Practice Question: A network automation script uses the Cisco DNAC…
A network automation script uses the Cisco DNAC Python SDK (dnacentersdk) to retrieve devices. Which method correctly lists all devices?
⚠ Common exam trap
Cisco often tests the exact method naming conventions in the SDK, and the trap here is that candidates confuse the generic Python list concept (e.g., `list_devices()`) with the SDK's actual method name (`get_device_list()`), or they assume a top-level method exists without the resource hierarchy.

Correct answer & explanation
✓
dnac.devices.get_device_list()
The Cisco DNAC Python SDK (dnacentersdk) uses a hierarchical method structure where the `devices` resource is accessed via `dnac.devices`, and the `get_device_list()` method is the exact SDK call to retrieve all devices from the Cisco DNA Center. This matches the official SDK documentation and the REST API endpoint `/dna/intent/api/v1/network-device`.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
dnac.get_devices()
Why it's wrong here
get_devices is not a method on the dnacentersdk object; device retrieval lives under the devices namespace, so this call fails. It is tempting because it reads like a direct REST GET, which suits raw requests-based scripts rather than the SDK's namespaced API.
- ✓
dnac.devices.get_device_list()
Why this is correct
get_device_list() is the dnacentersdk method that queries the DNA Center devices endpoint and returns all discovered devices. It satisfies the script's requirement to list every device, unlike methods that fetch a single device by ID or return unrelated inventory objects.
- ✗
dnac.sites.get_site_devices()
Why it's wrong here
get_site_devices returns devices assigned to a specific site, requiring a site identifier, so it cannot enumerate all devices. It is the correct call when scoping inventory to one site, not for a full device listing.
- ✗
dnac.devices.list_devices()
Why it's wrong here
The dnacentersdk exposes device retrieval through the devices namespace as get_device_list, so list_devices does not exist and raises an attribute error. It is tempting because list-style naming mirrors many REST SDKs, but those SDKs wrap different endpoints.
