In Junos, which command would you use to save your configuration changes?

The command to save configuration changes in Junos is 'commit'. When you make changes to the configuration, those changes are initially in a candidate configuration state. By using the commit command, you make your changes active in the running configuration. This action ensures that the modifications you’ve made are applied and will persist across reboots.

Understanding this process is essential, as simply editing the configuration does not apply the changes until the commit command is issued. This mechanism allows network engineers to review and ensure that configurations are correct before applying them, providing a layer of safety to the network management process.

The other commands listed do not serve the specific purpose of saving configuration changes in Junos. For instance, install might relate to software or feature installation, while save and store are not recognized as valid commands in the context of saving configurations.
