Solution:-

Copy run start

The correct answer is A. json_final = json.loads(json_data).

When using Python on Cisco devices:

The cli() function returns output as a string

To work with structured data, the string must be converted into a JSON object (Python dictionary)

The exhibit shows:

json_data = cli(cmd)

json_final = json.import(json_data)

This is incorrect because:

json.import() is not a valid Python function

The script fails to convert the JSON string into a Python object

json_final = json.loads(json_data)

json.loads() parses a JSON-formatted string

Converts it into a Python dictionary

Enables access using keys like:

json_final[ " TABLE_intf " ][ " ROW_intf " ][0] [ " prefix " ]

B. This line assumes the JSON is already converted into an object. It does not fix the conversion issue.

C. Incorrect syntax and unnecessary; json is already imported properly.

D. Just defines a command string; does not address JSON conversion.

Always remember the difference:

json.loads() → String → Python object

json.dumps() → Python object → String

Correct Automation Workflow:

Run CLI command

Capture output (string)

Convert using json.loads()

Parse using dictionary keys

This is a core concept for Cisco automation questions in the ENCOR exam.
