XK0-006 A user cannot start the Apache web service Practice Question
A user cannot start the Apache web service. The command 'systemctl start httpd' returns 'Failed to start httpd.service: Unit not found.' What is the most likely cause?
⚠ Common exam trap
It's easy for candidates to confuse a missing package with a service that is installed but not enabled or has configuration issues, leading them to select options like incorrect permissions or network configuration instead of recognizing the fundamental absence of the service unit.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The httpd package is not installed
The error 'Failed to start httpd.service: Unit not found' indicates that systemd cannot locate a service unit file for httpd. This most commonly occurs when the httpd package (Apache HTTP Server) is not installed on the system. Without the package, no service unit file exists under /usr/lib/systemd/system/, so systemctl cannot start the service.
