The command that confirms the current default target of the system is `systemctl get-default`. This command specifically retrieves and displays the name of the default target that is set to boot when the system starts up. Targets in systemd serve as organizational units that group related services and functions, so knowing which one is the default is critical for understanding the system's run level or operational state.

In contrast, while `systemctl status default.target` provides detailed status information about the default target, including whether it is active or inactive, it does not explicitly show which target is currently set as the default. The command `systemctl show default.target` lists the properties of the default target but again does not provide a straightforward display of which target is set as default. Lastly, `systemctl list-units` displays all loaded units and their current states, which can include all targets but does not specifically point out which one is configured as the default. Thus, for simply confirming the current default target, `systemctl get-default` is the most direct and appropriate command to use.
