A. B. C. D.C
The command that gracefully shuts down the Junos OS is "request system halt". This command stops all processes and cleanly shuts down the system, allowing any active sessions or processes to finish before the system powers off.
Let's break down each of the options to understand why "request system halt" is the correct choice:
A. "request system reboot" will reboot the system, but it does not guarantee a graceful shutdown. Any active sessions or processes may be abruptly terminated, which can result in data loss or corruption.
B. "request system logout" logs out the current user, but it does not shut down the system. It is simply a command to exit the CLI session.
C. "request system halt" is the correct command for a graceful shutdown. It stops all processes and cleanly shuts down the system, allowing any active sessions or processes to finish before the system powers off.
D. "restart gracefully" is not a valid command in Junos OS.
In summary, if you want to gracefully shut down the Junos OS, use the "request system halt" command.
