Why each option
The `monitor interface traffic` command provides a real-time view of interface usage details, showing live traffic statistics.
`show interfaces terse` displays a concise summary of interface status and basic statistics, not real-time usage.
`show interfaces extensive` provides detailed, static information about interfaces, including statistics, but it does not update in real time.
The `monitor interface traffic` command provides a dynamic, real-time view of traffic flowing through specified interfaces, including input and output rates. This is essential for live troubleshooting and monitoring current network performance.
`monitor traffic interface` is not a valid Junos OS command syntax.
