XK0-006 Practice Question: After a system update, a server takes…
After a system update, a server takes significantly longer to boot. The administrator wants to identify which systemd service is causing the delay. Which command provides a detailed analysis of boot time spent by each service?
⚠ Common exam trap
Watch out — candidates often confuse `systemd-analyze blame` with `systemd-analyze critical-chain`, mistakenly thinking the latter provides per-service timing, when in fact it only shows the dependency chain and not the individual time spent by each service.

Correct answer & explanation
✓
systemd-analyze blame
The `systemd-analyze blame` command prints a list of all running systemd units, sorted by the time they took to initialize during boot. This directly answers the administrator's need to identify which specific service is causing the delay, as it shows the exact time spent by each service.
