LFCS Service Configuration Practice Question
A system administrator needs to ensure the Apache httpd service starts automatically on system boot. Which command should they use?
⚠ Common exam trap
A common mix-up: candidates confuse `systemctl start` (immediate runtime action) with `systemctl enable` (persistent boot-time configuration), leading candidates to choose the command that works now but fails after a reboot.
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
✓
systemctl enable httpd
The `systemctl enable httpd` command creates the necessary symlinks in the systemd unit configuration directories (typically `/etc/systemd/system/multi-user.target.wants/`) to ensure the Apache httpd service starts automatically at boot time. This is the correct approach because `enable` configures the service to be started on system startup, whereas `start` only runs it immediately without affecting boot behavior.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
systemctl enable httpd
Why this is correct
systemctl enable creates symlinks for automatic start at boot.
- ✗
systemctl start httpd
Why it's wrong here
systemctl start only starts the service immediately, does not enable boot start.
- ✗
systemctl disable httpd
Why it's wrong here
systemctl disable removes symlinks, preventing boot start.
- ✗
systemctl reload httpd
Why it's wrong here
systemctl reload reloads configuration without changing enable status.
