What is the primary purpose of using indentation and whitespace in JSON formatting?

To reduce the file size for faster network transmission.

To improve human readability of the data structure.

To indicate the data type of each value.

To make the JSON valid only when indentation is used.

You are creating a JSON configuration file that will be reviewed by a colleague before being committed to a Junos device. The file is currently a single line of JSON. To make it easier for your colleague to read, you want to format it with indentation. Which Python code will produce a human-readable, indented JSON string?

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

Which JSON data type is represented by the value `null`?

A null value, indicating the absence of a value.

You are writing a JSON configuration file for a Junos device that will be stored in a version control system. You want to ensure that the file is consistently formatted so that diffs are easy to review. Which practice should you follow?

Use a consistent indentation level (e.g., 2 or 4 spaces) throughout the file.

Minify the JSON to a single line to reduce file size.

Use tabs for indentation to save space.

Add comments to explain each section of the configuration.
