Listing ntpd peers | LinuC Level 1 102 Exam original practice question

1.09.1Basic

Display ntpd's time-source associations, selected peer, reachability, and offset in a table.

Which command is appropriate?

Hint 1: Focus on clock layers

Separate the system clock, RTC, timezone rules, and NTP synchronization before comparing the commands or settings.

Hint 2: Key terms

Review the short definitions of system clocks, RTC, timezones, and NTP synchronization involved.

ntpd: A traditional daemon that continuously synchronizes with NTP time sources.
ntpq -p: The form that queries ntpd and displays its peer and synchronization table.
Peer table: A table of source stratum, reachability, delay, and offset measurements.
Reachability: Status information showing whether a time source has recently responded.
chronyc sources: The chrony operation that lists the time sources used by chronyd.

Detailed explanation

Incorrectntpd -p

Incorrect. ntpd is the daemon, not the peer-query command.

Incorrectntpdate -p

Incorrect. ntpdate is for one-shot synchronization.

Incorrectchronyc -p

Incorrect. chronyc uses commands such as sources rather than ntpq syntax.

Correctntpq -p

Correct. ntpq -p displays ntpd peers.

An example you can run in a temporary verification environment.

ntpq --help 2>&1 | grep -E -- '-p' | head -n 1
