Correct Answer: C
JSON represents data as structured name/value pairs, arrays, objects, strings, numbers, Booleans, and null values. In the exhibit, Option C is the output that follows JSON syntax: field names are enclosed in double quotes, values appear after colons, and objects or arrays are delimited with braces or brackets. XML would use opening and closing tags. YAML normally relies on indentation and key-value formatting without the same heavy brace structure. Plain text or CLI output does not follow a strict object model. Cisco CCNA v1.1 Automation and Programmability includes recognizing data formats used with APIs and automation tools.
That is the practical reason JSON appears so often in controller-based networking and REST APIs: it is compact, structured, and easy for software to parse. The key exam check is visual. If you see quoted keys, colons, braces, brackets, and comma-separated values arranged as objects or arrays, you are looking at JSON.
