What is the practice of saving a copy of a device's current configuration before making changes?

• A. Running Config
• B. Startup Config
• C. Configuration Backup
• D. Baseline

Answer: (C)

Saving a copy of the device’s current configuration before making changes is called a configuration backup. This practice creates a saved snapshot of how the device is configured at that moment, so if the new changes cause problems, you can restore to the known-good state quickly. In many environments, you’d back up the running configuration to a stable location (like the startup configuration, or an external file or repository) so you have a reference you can revert to after edits. The other terms describe related ideas but not the action of saving a backup: the running configuration is the active settings in memory, the startup configuration is what the device loads on boot, and a baseline is a reference configuration used for comparison or standardization.
