Why is JSON commonly used for data exchange in automation scripts and APIs?

It is a compiled format that requires special software to parse.

It is a proprietary format used only by Juniper devices.

It is a lightweight, text-based format that is easy for both humans and machines to read and parse.

It is a binary format that is faster to transmit than text.

What is the result of parsing the JSON string `'{"status": "up"}'` with `json.loads()` in Python?

A Python list: ['status', 'up']

A Python tuple: ('status', 'up')

A Python string: '{"status": "up"}'

A Python dictionary: {'status': 'up'}

You are writing a Python script that serializes a list of route objects to JSON. Each route is a dict with keys 'prefix' (string) and 'next-hop' (string). You need to ensure the JSON output is sorted by key for consistent output. Which code snippet correctly does this?

json.dumps(routes, sort_keys=True)

json.dumps(routes, separators=(',', ':'))
