200-901 Practice Question: Refer to the exhibit

Exhibit

{
  "id": "N_12345",
  "name": "Main Office",
  "timeZone": "America/New_York",
  "tags": ["production", "primary"],
  "netflow": {
    "enabled": false,
    "collectorPort": 2055,
    "collectorIp": "10.0.0.1"
  }
}

Refer to the exhibit. A Python script parses this JSON response to check if NetFlow is enabled on the network. Which code snippet correctly checks the NetFlow status?

⚠ Common exam trap

Cisco often tests the difference between JSON boolean values and their string representations, trapping candidates who treat `true`/`false` as strings instead of Python booleans, and also tests safe dictionary access methods versus direct key access that can raise exceptions.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

if response['netflow'].get('enabled', False):

It uses the `.get()` method with a default value of `False` to safely access the `enabled` key within the `netflow` dictionary. This handles cases where the key might be missing or the value is `False`, avoiding a `KeyError` and correctly evaluating the boolean condition. In JSON, the `enabled` field is typically a boolean, so checking truthiness directly is the proper approach.

Answer analysis

Option-by-option breakdown

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

  • ✓

    if response['netflow'].get('enabled', False):

    Why this is correct

    Safely checks for the 'enabled' key with a default of False.

  • ✗

    if response['netflow']['enabled'] == 'true':

    Why it's wrong here

    The value is a boolean false, not the string 'true'.

  • ✗

    if response.netflow.enabled:

    Why it's wrong here

    This syntax is invalid for a dict; it would cause an AttributeError.

  • ✗

    if response['netflow']['enabled']:

    Why it's wrong here

    This would raise a KeyError if 'netflow' or 'enabled' key is missing.
