You have inherited a systemd machine and want to know, before rebooting it, which target it will come up in. Type the command that prints the configured default target.
LPIC-1 Exam 101-500, objective 101. System architecture easy
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.
Answer
Type the answer.
Accepted answers
systemctl get-default/usr/bin/systemctl get-default/bin/systemctl get-default
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
systemctl get-default resolves and prints what /etc/systemd/system/default.target points at, for example graphical.target. Its counterpart systemctl set-default replaces that symlink, so the pair are the systemd equivalents of reading and writing the initdefault line in /etc/inittab. Neither reports or changes the state the machine is in at this moment: `systemctl list-units --type=target` shows which targets are active now, and systemctl isolate switches between them without altering the next boot.

Reading one question is not practice. The trainer will draw a short set from objective 101 and space the ones you get wrong.
