On a systemd host, type the single command that turns on automatic network time synchronisation (do not include a path).
LPIC-1 Exam 102-500, objective 108. Essential system services medium
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.

Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
`timedatectl set-ntp true` asks systemd to enable and start whichever installed NTP client unit it knows about — systemd-timesyncd by default, or chronyd/ntpd if the distribution registered one. The boolean accepts true/on/yes/1 and their negatives. `timedatectl status` then shows a line reporting whether the system clock is synchronised and whether the NTP service is active. Note that timedatectl only toggles the service; it does not edit the server list, which stays in timesyncd.conf, chrony.conf or ntp.conf.
Where this comes from

- LPI exam objective 108.1
- What it says
- Use timedatectl to configure system time and time synchronisation.
Practise this
Reading one question is not practice. The trainer will draw a short set from objective 108 and space the ones you get wrong.
