LPIC-2 Linux Kernel and System Startup Practice Question
This LPIC-2 practice question tests your understanding of linux kernel and system startup. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization is migrating from SysV init to systemd. What systemd command should be used to check the status of the HTTP service?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
systemctl status httpd
The correct command to check the status of a service in systemd is `systemctl status httpd`. This command displays the current state, recent log entries, and process details for the specified unit. The `systemctl` utility is the primary interface for managing systemd services, while `systemd` itself is the init system daemon, not a user-facing command.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
systemd-analyze httpd
Why it's wrong here
systemd-analyze is used for analyzing boot performance, not for checking service status.
✗
systemctl list-units httpd
Why it's wrong here
list-units lists all units, but does not show detailed status of a single service.
✗
systemd status httpd
Why it's wrong here
systemd is the init system itself, not a command; systemctl is the correct tool.
✓
systemctl status httpd
Why this is correct
This command shows whether the service is active, enabled, and other details.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse `systemd` (the daemon) with `systemctl` (the control tool), leading them to choose `systemd status httpd` instead of the correct `systemctl status httpd`.

Command / output trap
list-units lists all units, but does not show detailed status of a single service.
Detailed technical explanation
How to think about this question
Under the hood, `systemctl status httpd` reads the unit's state from the systemd journal and the unit's control group (cgroup) information via the D-Bus interface. It also parses the unit's `ActiveState`, `SubState`, and `MainPID` properties, and if the service is running, it displays the last few log entries from the journal. In real-world scenarios, this command is essential for troubleshooting because it shows not only whether the service is running but also recent errors, the command line used to start it, and the process ID, which helps correlate with other system logs.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the LPIC-2 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
