Checking the default target | LinuC Level 1 101 Exam original practice question

1.01.3Basic

Inspect the target systemd will use for the next normal boot without changing it.

Which command is appropriate?

Hint 1: Focus on the requirement

The requirement is a non-destructive query, so select the verb that only reads the configured default.

Hint 2: Key terms

Review the short definitions before comparing the boot and systemd choices.

get-default: The systemctl verb that displays the configured default target.
default.target: The conventional alias for the target chosen as the boot default.
Read-only query: An operation that reports configuration without changing it.

Detailed explanation

Incorrectsystemctl isolate default.target

Incorrect. isolate changes the current target.

Incorrectsystemctl enable default.target

Incorrect. enable changes boot-time activation and is not a read-only query.

Correctsystemctl get-default

Correct. systemctl get-default displays the configured default target.

Incorrectsystemctl reboot --dry-run

Incorrect. reboot changes system state rather than inspecting the default.

An example you can run in a temporary verification environment.

systemctl get-default 2>/dev/null || true

multi-user.targetやgraphical.target等

Environment: systemd採用Linux
Use read-only commands or a disposable Linux instance when checking boot metadata.
Exact unit names and command output can vary slightly by distribution.

Foundation review

get-default reports the default target; isolate and set-default have different state-changing effects.

Run the query before changing a target so the current configuration is recorded.
