_____ - is used to store the startup-configuration file.

Explanation:
The startup configuration needs to persist across reboots, so it must be stored in non-volatile memory. When the device boots, it loads this startup configuration from non-volatile storage into RAM to build the running configuration for the session. Non-volatile RAM is designed to keep data even when power is lost, unlike regular RAM which loses its contents as soon as power is removed. That’s why the startup configuration sits in NVRAM. RAM, by contrast, holds the current running configuration that the device uses while it’s on; it can be changed during operation but wouldn’t survive a power cycle. FLASH is typically used for storing the IOS image, not the device’s configuration. ROM contains a bootstrap loader and minimal firmware, not the full startup configuration. So, storing the startup configuration in NVRAM is the correct choice because it ensures the configuration is retained after power cycles and can be loaded during boot.
