When using the commit confirmed option, how much time do you have to confirm the configuration before it automatically rolls back?

The commit confirmed option in Junos OS provides a way to temporarily commit configuration changes while allowing you to verify that the changes work as intended. If you do not confirm the commit within the specified time frame, the system will automatically roll back to the previous configuration to prevent any disruption due to configuration errors.

In this case, the correct time limit is 60 seconds. This one-minute window gives users a reasonable amount of time to test the changes after they are applied. If the configuration is functioning as expected, you can issue the confirmation command to maintain the new settings. If not, the system reverts to the previous, stable configuration automatically, ensuring that network availability is not compromised.

The other options do not provide sufficient time for adequately testing the configuration changes and, therefore, would not align with the expected functionality of the commit confirmed feature in Junos OS.
