A network administrator wants to verify the active alarms on interface so-0/0/0.0. Which command displays this information?

`show interfaces alarms` is not a standard Junos command. While you are looking for alarms, the command structure is incorrect.

`show interfaces terse` provides a brief summary and does not include detailed alarm information for a specific interface.

`show alarms extensive` displays system-wide active alarms, not alarms specific to a particular interface, unless the alarm itself identifies the interface. To explicitly see interface-specific alarms, you need the detailed interface view.

The `show interfaces extensive` command provides comprehensive details about a specified interface, which includes not only its statistics and properties but also any active alarms or error conditions that are affecting that particular interface. To check alarms on a specific interface, this is the command that will show it within the interface's detailed output.
