When you run copy running-config startup-config, what is the result?

• A. The new configuration will be stored in flash memory.
• B. The new configuration will be loaded if the switch is restarted.
• C. The current IOS file will be replaced with the newly configured file.
• D. The configuration changes will be removed and the original configuration will be restored.

Answer: (B)

Saving the current configuration to startup configuration ensures it survives a reboot. The running configuration is the active one in RAM, while the startup configuration lives in non-volatile memory and is what the device loads when it boots. By copying, you write the RAM-based settings into NVRAM, so when the switch restarts, the startup configuration is loaded into RAM as the new running configuration. This is why the new configuration will be loaded if the switch is restarted. This action only saves the current settings; it doesn’t change the IOS image in flash.
