Which two backup scenarios exist for enabling configuration archival on a Junos OS device?

Enabling configuration archival on a Junos OS device can indeed occur based on specific time intervals, allowing for automated backups at regular intervals to ensure that configuration changes are captured without requiring manual intervention. This is particularly useful for maintaining a history of configuration changes over time, helping to track the evolution of network settings.

This automated backup process is efficient for network management, as it can help administrators quickly restore previous configurations if needed, or analyze changes made over specific periods. The ability to set parameters for time intervals is a core feature of the configuration archival system in Junos OS, making it a versatile tool in any network administrator's toolkit.

Other options, while they may reflect actions related to configuration management, do not operate as formal triggers for the archival process itself. For instance, manual backups obviously require user interaction, and while system restarts could prompt certain actions, they are generally not an archival function. Likewise, a commit operation does not trigger a backup of the entire configuration but rather applies changes to the current configuration state.
