A system administrator needs to ensure a specific service starts automatically on system boot. Which of the following systemctl subcommands would allow the administrator to achieve this?
The correct answer is enable. The systemctl enable command is used to create a set of symlinks, so the specified unit is started automatically during the boot process. start only initiates the service immediately but does not configure it to start on boot. status provides the current status of the unit and does not modify its startup behavior. reload is used to re-read the configuration of a service without interrupting its operation.
