A network administrator needs to save the configuration file currently in ram to nvram before rebooting the switch which command should the administrator issue?

The network administrator should issue the command copy running-config startup-config or its shorthand wr (write memory) to save the current configuration file from RAM to NVRAM. This ensures that the configuration persists after the switch is rebooted. After executing this command, the administrator can safely reboot the switch without losing any changes made.
