How can you delete configuration stored in NVRAM?

The process of deleting configuration stored in NVRAM is crucial for devices that use this type of memory to retain settings even after rebooting. When you need to clear the startup configuration—which is what is stored in NVRAM—issuing the command to erase the startup configuration is the correct approach. This command removes the saved configuration that the device loads upon restart, allowing for a fresh start and reconfiguration as necessary.

Using the command to erase startup clears the configuration that resides in NVRAM, while other related commands do not specifically target the startup configuration stored in NVRAM. This helps in scenarios where a device might be misconfigured, and you need to revert to a factory-like state or start over with a new configuration without the previous parameters affecting operations.
