Holds the startup-configuration, which is loaded to the RAM upon bootup and then becomes the running-config.

• A. NVRAM
• B. RAM
• C. ROM
• D. Flash Memory

Answer: (A)

Startup configuration is kept in non-volatile memory so it isn’t lost when power is removed. The startup-configuration lives in NVRAM. On boot, the device reads that startup-config from NVRAM and loads it into RAM as the running-config, which is the active configuration the system uses. If you modify settings, you typically save the running-config back to startup-config in NVRAM to preserve the changes across reboots. ROM holds the bootstrap code, and Flash stores the IOS image and other files, but the startup-config itself resides in NVRAM.
