A network engineer is using the Cisco DNA Center REST API to retrieve the list of devices. The API call returns the following JSON response:
```json
{
"response": [
{
"id": "device-123",
"hostname": "Router1",
"managementIpAddress": "10.10.20.1",
"softwareVersion": "17.3.3",
"platformId": "ISR4451-X/K9"
},
{
"id": "device-456",
"hostname": "Switch1",
"managementIpAddress": "10.10.20.2",
"softwareVersion": "16.12.5",
"platformId": "C9300-24P"
}
],
"version": "1.0"
}```
The engineer wants to filter the results to only show devices with software version 17.3.3. Which of the following API query parameters should be used?

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
/dna/intent/api/v1/network-device?softwareVersion=17.3.3
Why this is correct
The DNA Center API allows filtering by softwareVersion directly in the query string.
- ✗
/dna/intent/api/v1/network-device?version=17.3.3
Why it's wrong here
'version' is not a valid filter; it refers to the API version, not the software version.
- ✗
/dna/intent/api/v1/network-device?osVersion=17.3.3
Why it's wrong here
The correct parameter is 'softwareVersion', not 'osVersion'.
- ✗
/dna/intent/api/v1/network-device?filter=softwareVersion:17.3.3
Why it's wrong here
DNA Center does not use a generic 'filter' parameter; it uses specific query parameters.
