Which command is used to start the OpenVPN service on a Unix-based system?

• A. sudo start openvpn
• B. openvpn --start
• C. service openvpn start
• D. openvpn --run

Answer: (C)

The command used to start the OpenVPN service on a Unix-based system is typically associated with system service management practices. Using the "service" command followed by the service name and the "start" argument is a widely accepted method for controlling services in Unix-like operating systems. When executing "service openvpn start," the system recognizes this as a command to communicate with the service management framework, specifically to initiate the OpenVPN service. This method is especially useful in distributions that utilize the SysVinit or systemd system management protocols, allowing for seamless interaction with the underlying service management tools. In contrast, other provided options may represent misunderstandings or variations not recognized by standard service management techniques. For instance, "sudo start openvpn" does not follow proper syntax for starting services in most systems. "openvpn --start" and "openvpn --run" do not correspond to valid command usage for initiating a service as they suggest running the OpenVPN application directly rather than interfacing with the service management system. Hence, the third option is the correct approach for starting the OpenVPN service efficiently and effectively in typical Unix-based environments.
