What information does the help reference command provide?

A

The help reference command provides a brief description of Junos OS commands and their default values. It is a useful tool for exploring the various commands and their functions. The help reference command is typically entered at the CLI prompt, followed by the name of the command or keyword for which help is needed.

For example, if a user wanted to learn more about the configuration command, they would enter the following:

shellCopy code
user@router> help reference configuration 

This would display information about the configuration command, including its syntax, default values, and a brief description of its function.

The help reference command does not provide information about the serial number or version number of the device, nor does it display active hardware alarms. Additionally, the help reference command does not display the current configuration while in operational mode.

In summary, the correct answer is A. The help reference command provides a brief description of commands and their default values.
