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

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 aconfiguration 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.
