Which command isolates the system into the graphical.target?

• A. systemctl isolate graphical.target
• B. systemctl switch graphical.target
• C. systemctl enter graphical.target
• D. systemctl chroot graphical.target

Answer: (A)

In systemd, targets represent specific states of the system, and you transition between them using systemctl. The isolate action switches the running system to the exact target you specify by stopping units that aren’t part of that target and starting the units that are. This makes the system enter a clean, defined state corresponding to that target.

Graphical.target is the state where the graphical user interface and related services (like a display manager) are active. Using isolate here brings the system into GUI mode, ensuring GUI components are up while stopping services that aren’t needed for graphical operation.

The other options aren’t valid ways to perform this switch. switch isn’t a recognized systemctl subcommand, enter isn’t a systemctl action, and chroot is a separate operation unrelated to switching system runlevels or targets.
