Question

On which two components of a router can a copy of a running-configuration file be saved manually by an engineer for backup purposes? (Choose two.)

Options

ANVRAM
BFlash
CROM
DRAM
EDRAM

Explanation

NVRAM and Flash are the two non-volatile storage components on a Cisco router where a running configuration can be manually saved for backup.

Common mistakes.

C. ROM contains the bootstrap program and POST routines and is read-only; it cannot be written to by an engineer.
D. RAM holds the running configuration while the router is operational, but it is volatile - its contents are lost when the device is powered off or reloaded.
E. DRAM is the physical memory technology used to implement RAM on a router; it is equally volatile and cannot be used as a persistent backup location.
