A network administrator is planning to update the configurations on several critical network devices. To adhere to best practices in configuration management, what is the most important action that should be performed before applying the new configurations?
It is essential to back up the current configurations before any changes are made. This allows the network to be restored to its previous state if the new configurations lead to issues or failures. This practice ensures minimal service disruption and provides a recovery point. Making notes of performance metrics helps to compare before and after states but does not safeguard against configuration errors. While informing the IT team is a good practice for awareness, it does not directly protect against potential configuration issues.
