Question 2,001 of 2,015

REST APIs and Data Models →hardMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is to use the query parameter `?softwareVersion=17.3.3` appended to the `/dna/intent/api/v1/network-device` endpoint. This works because the Cisco DNA Center REST API allows filtering of device inventory by appending key-value query parameters directly to the base URI, where `softwareVersion` is the exact attribute name used in the JSON response to match the desired version. On the ENCOR 350-401 exam, this tests your understanding of REST API filtering syntax versus post-processing data in code—a common trap is trying to filter with a body parameter or using an incorrect key like `version` or `swVersion`. Remember that DNA Center API filters mirror the JSON key names exactly, so always check the response schema for the precise attribute. A handy memory tip: "Filter by the field name you see in the JSON output" — if the JSON shows `"softwareVersion"`, your query parameter must be `softwareVersion`.

CCNP REST APIs and Data Models Practice Question

This 350-401 practice question tests your understanding of rest apis and data models. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

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?

Question 1hardmultiple choice

Review the full routing breakdown →

A
/dna/intent/api/v1/network-device?softwareVersion=17.3.3
The DNA Center API allows filtering by softwareVersion directly in the query string.
B
/dna/intent/api/v1/network-device?version=17.3.3
Why wrong: 'version' is not a valid filter; it refers to the API version, not the software version.
C
/dna/intent/api/v1/network-device?osVersion=17.3.3
Why wrong: The correct parameter is 'softwareVersion', not 'osVersion'.
D
/dna/intent/api/v1/network-device?filter=softwareVersion:17.3.3
Why wrong: DNA Center does not use a generic 'filter' parameter; it uses specific query parameters.

Correct answer & explanation

✓

/dna/intent/api/v1/network-device?softwareVersion=17.3.3

DNA Center API supports filtering using query parameters. The correct parameter to filter by software version is 'softwareVersion'.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A practitioner preparing for the 350-401 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

What to study next
