Why each option
The `monitor interface <interface-name>` command provides real-time, dynamic updates of an interface's operational state, input/output rates, and error statistics. This command is ideal for live troubleshooting and observing current traffic patterns.
The `monitor interface <interface-name>` command displays real-time statistics for the specified interface, dynamically updating the screen with information such as input/output rates, errors, and interface status. This is precisely what is needed to view real-time interface usage.
`traceoptions` is used to log debugging information to a file, not to display real-time usage directly on the console.
`debug` commands are used for collecting detailed diagnostic information for specific processes or protocols, not for general real-time interface usage statistics.
`monitor usage` is not a standard Junos command for real-time interface usage; the correct syntax is `monitor interface`.
