Which Cisco Internetwork Operating System (IOS) command is used to copy the configuration stored in
Random Access Memory (RAM) to Non-Volatile Random Access Memory (NVRAM)?
A.
router# copy running-config startup-config
B.
router(config)# copy running-config startup-config
C.
router# copy startup-config running-config
D.
router(config)# copy startup-config running-config
Explanation:
The router# copy running-config startup-config command is used to copy the configuration stored in Random
Access Memory (RAM) to Non-Volatile Random Access Memory (NVRAM). This command is issued in
privileged EXEC mode. The syntax of the command is as follows:
router# copy running-config startup-config
The parts of the command are as follows:
running-config is the running configuration stored in RAM.
startup-config is the startup configuration stored in Non-Volatile Random Access Memory (NVRAM).
The router(config)# copy running-config startup-config command is incorrect because the copy run start
command (abbreviated) is not issued in global configuration mode. It is executed in privileged EXEC mode.
The router# copy startup-config running-config command is incorrect because this command is used to copy
the configuration stored in NVRAM to RAM.
The router(config)# copy startup-config running-config command is incorrect because neither the copy run start
nor the copy start run commands are executed in global configuration mode. Moreover, the copy startup-config
running-config command is used to copy the configuration stored in NVRAM to RAM.
