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
Draft — not checked yet. This question was written from the published exam objectives and cites the clause it comes from, but nobody has yet read it against that clause and signed for it.
It is kept out of search results and out of mock exams until they have. Read the source below before you take the answer as settled.

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.
