What command is used to save the running configuration to startup configuration?

copy run start
write memory
save config
backup configuration

The correct answer is: copy run start

The command used to save the running configuration to the startup configuration is "copy run start." This command directs the device to take the current operating configuration, which is stored in the running memory (RAM), and copy it into the startup configuration file located in non-volatile memory (NVRAM). This action ensures that the changes made during the current session are preserved and loaded the next time the device is rebooted. "Write memory," while also effective for saving configurations, is a legacy command that primarily serves the same purpose as "copy run start." However, it is generally recommended to use the "copy" command for clarity and consistency, particularly for those preparing for certification exams like the CCNA. The other options, such as "save config" and "backup configuration," are not recognized commands within Cisco's IOS environment for saving configuration settings. Using non-standard commands can lead to confusion and an understanding gap for students studying for their CCNA certification. Understanding the correct command and its function is critical for effective network management and troubleshooting.
