Why each option
To make configuration changes on a Junos device, you must enter configuration mode, which allows you to modify the device's settings.
Enable mode is a common term in other network operating systems for privileged operational mode, but Junos uses 'operational mode' for monitoring and troubleshooting, not configuration.
Configuration mode is the specific CLI mode where you can view, edit, and commit configuration changes to the device's running configuration.
Operational mode in Junos OS is used for monitoring the device, troubleshooting, and executing 'show' commands, not for making configuration changes.
Active mode is not a standard CLI mode in Junos OS for making configuration changes.
