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.managementIpAddress
Why it's wrong here
This assumes attribute access; 'data' is a dict, not an object.
✗
data['response']['managementIpAddress']
Why it's wrong here
Misses the list index; 'response' is a list.
✗
data.get('response')[0].get('managementIpAddress')
Why it's wrong here
While syntactically valid, it is less direct and not the typical simple extraction.
✓
data['response'][0]['managementIpAddress']
Why this is correct
Correctly indexes into the list and retrieves the management IP.
