What command is used to delete the configuration stored in NVRAM?

The command used to delete the configuration stored in NVRAM is 'erase startup'. This command effectively removes the saved configuration file that the device uses to load its settings upon booting. When devices are powered on, they look for the configuration stored in NVRAM (non-volatile random-access memory) to apply the previously saved settings. By issuing the 'erase startup' command, you ensure that the next time the device starts, it will not load any configurations, allowing for a fresh setup or reconfiguration.

This command is particularly useful when you want to reset a device to its default state, as it clears any custom settings or configurations that were previously stored. Users often employ this command when preparing a device for a new configuration, or when troubleshooting issues that may stem from incorrect settings.

The other options, while sounding similar, do not correctly represent the command required to clear the startup configuration from NVRAM. Understanding which command to use in this context is critical for managing device configurations effectively.
