Cisco routers and switches use two configuration files Where

Cisco routers and switches use two configuration files. Where is the configuration file used at device bootup stored?

A. RAM

B. ROM

C. Flash

D. NVRAM

Solution

D is correct. The startup configuration is used during the device bootup process and is stored in NVRAM—a nonvolatile storage location retaining all information after power off.

A, B, and C are incorrect. A is incorrect because RAM is volatile and is used to store the running configuration. B is incorrect because ROM holds a bootstrap program and the ROMMON basic operating system. C is incorrect because flash memory holds a copy of the IOS.
