200-901 Practice Question: Refer to the exhibit

Exhibit

{
  "response": [
    {
      "id": "1234",
      "name": "Switch1",
      "platformId": "C9300-24P",
      "softwareVersion": "16.12.5",
      "upTime": "30 days, 4 hours, 12 minutes"
    }
  ],
  "version": "1.0"
}

Refer to the exhibit. This JSON response was received from the Cisco DNA Center API. A developer wants to extract the software version of the first device. Which Python expression correctly retrieves '16.12.5' from the variable `data`?

⚠ Common exam trap

The trap here is that candidates often forget the 'response' wrapper and treat the JSON as a flat list, or confuse the key name 'version' with 'softwareVersion', which Cisco deliberately uses to test attention to exact field names in the API schema.

Correct answer & explanation

✓

data['response'][0]['softwareVersion']

The JSON response from Cisco DNA Center's API is structured with a 'response' key containing an array of device objects. To access the software version of the first device, you must first index into the array with [0] to get the first device object, then use the key 'softwareVersion' to retrieve the value '16.12.5'. The variable `data` holds the entire JSON object, so `data['response'][0]['softwareVersion']` correctly navigates this nested structure.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
data[0]['softwareVersion']
Why it's wrong here
Missing the 'response' key; data is a dictionary with 'response' key.
✗
data['response'][0]['version']
Why it's wrong here
'version' is at the top level, not inside the device object.
✗
data['response']['softwareVersion']
Why it's wrong here
Missing index; 'response' is an array, so you must specify index.
✓
data['response'][0]['softwareVersion']
Why this is correct
Correctly navigates the JSON hierarchy.
