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/issues

  Why it's wrong here

  This endpoint returns issue or assurance records, not the device inventory, and POST is used for creating or triggering resources. It tempts because issues relate to network health, but retrieving devices requires GET /dna/intent/api/v1/network-device, which lists managed devices.

• ✗

  POST /dna/system/api/v1/auth/token

  Why it's wrong here

  This endpoint authenticates and issues a token; it returns no device inventory. It tempts because every DNA Center API call needs that token first, so it appears in nearly every workflow, yet the question asks for the device-listing call itself, which is GET /dna/intent/api/v1/network-device.

• ✓

  GET /dna/intent/api/v1/network-device

  Why this is correct

  The `GET /dna/intent/api/v1/network-device` endpoint retrieves all network devices from Cisco DNA Center, satisfying the stem’s requirement to “retrieve a list” by using the HTTP GET method, which is idempotent and safe for read-only operations. This contrasts with POST, which would create a new resource, and DELETE, which would remove devices. The path’s `/network-device` resource collection directly maps to the requested data set.

• ✗

  GET /dna/intent/api/v1/topology/l2/{vlanID}

  Why it's wrong here

  This endpoint returns Layer 2 topology for a specified VLAN, not a device inventory, and requires a VLAN ID path parameter. It tempts because topology data involves network devices, but listing all managed devices uses GET /dna/intent/api/v1/network-device instead.
