Final answer:
The correct commands to save the current running configuration to NVRAM are 'Copy running-config startup-config' and 'Write memory'. 'Save' and 'Reload' are not standard commands for this purpose.
Step-by-step explanation:
The question relates to the commands used on network devices like routers and switches to save the currently running configuration to the Non-Volatile Random Access Memory (NVRAM). The correct commands that save the current running configuration on NVRAM are:
- Copy running-config startup-config: This command copies the running configuration (which is stored in RAM) to the startup configuration (stored in NVRAM), ensuring that the configuration persists after a reboot.
- Write memory: Equivalent to the above command, 'write memory' is a shortcut for the same action of saving the running configuration to NVRAM.
The commands 'Save' and 'Reload' are not standard commands for saving configurations on such devices. 'Reload' is actually used to reboot the device.
