Cisco CCNA mock exam questions sample test – Question 354

.Which Cisco IOS command will enable a switch to copy the configuration from NVRAM to its RAM?

A. copy tftp flash
B. copy running-config flash
C. copy startup-config flash
D. copy startup-config running-config
E. copy running-config startup config

Correct Answer: D

Explanation:
The copy startup-config running-config command enables a switch (or a router) to copy configuration from NVRAM to its RAM. The configuration file located in NVRAM is referred to
as the startup configuration, and a configuration currently loaded and running in RAM is referred to as the running configuration.
The copy running-config startup-config command is incorrect because it will save your running configuration in RAM to the non-volatile NVRAM, which is the reverse of the scenario’s
requirement. This would be the required command to run if you have edited the running configuration and would like to save the changes so that they are effective the next time you
restart the switch.
The copy tftp flash command does not enable a switch to copy the configuration from NVRAM to its RAM. This command is used to restore backup IOS images stored on a TFTP
server to the target switch (or router).
The copy running-config flash command does not enable a switch to copy the configuration from NVRAM to its RAM. This command is used to save the running configuration in RAM
to the switch’s flash memory.
The copy startup-config flash command does not enable a switch to copy the configuration from NVRAM to its RAM. This command is used to save the startup configuration in
NVRAM to the switch’s flash memory.
