XK0-006 Practice Question: Refer to the exhibit
Exhibit
[Unit] Description=My custom service After=network.target [Service] ExecStart=./myscript Restart=always [Install] WantedBy=multi-user.target
Refer to the exhibit. A Linux administrator created a systemd service file for a custom script. When starting the service, it fails with 'Unit myservice.service entered failed state.' Which of the following is the most likely cause?
⚠ Common exam trap
CompTIA often tests the requirement for absolute paths in ExecStart, and the trap here is that candidates may assume relative paths are acceptable or that the [Install] section is mandatory for starting a service, when in fact it is only for enabling.
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 ExecStart path is relative
The most likely cause is that the ExecStart path is relative. Systemd requires absolute paths for ExecStart directives; a relative path (e.g., `./script.sh` or just `script.sh`) will cause the unit to fail immediately because systemd cannot resolve the executable location. The error 'entered failed state' typically results from this path resolution failure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The ExecStart path is relative
Why this is correct
Systemd requires absolute paths; a relative path causes the service to fail.
- ✗
The service type should be forking
Why it's wrong here
The default type 'simple' works for foreground processes.
- ✗
The service file lacks an [Install] section
Why it's wrong here
The [Install] section is present, so this is not the cause.
- ✗
The Requires directive is missing
Why it's wrong here
No dependencies are needed for this service.
