What command would you type to view the differences between the active and the candidate configuration?

The command "show | compare" is used in Junos OS to view the differences between the active configuration and the candidate configuration. This command effectively summarizes the changes that have been made in the candidate configuration as compared to what is currently active on the device.

When executed, it provides a clear output of what modifications have been introduced in the candidate state, allowing network administrators to assess these changes before committing them. This capability is essential for ensuring that any configuration changes can be reviewed in detail and understood fully before they are implemented, thereby minimizing potential disruptions to network operations.

Other commands listed may not exist in this context or would not serve the same purpose in Junos OS. Thus, "show | compare" is the standard method for comparing configurations in Junos devices.
