CompTIA Linux+ (XK0-006) — Question 8

A Linux administrator needs to change the execution frequency of a systemd timer. Which of the following commands should the administrator use after editing the timer file to make the changes effective?

Answer options

• A. systemctl daemon-reload
• B. timedatectl --adjust-system-clock
• C. systemd-ana1yze time
• D. sysctl --load

Correct answer: A

Explanation

The correct command is 'systemctl daemon-reload', which reloads the systemd manager configuration to recognize changes made to unit files, including timers. The other options do not affect the systemd timer or its configuration; 'timedatectl' manages time settings, 'systemd-analyze' is for performance analysis, and 'sysctl' is for kernel parameter management.
