LFCS Service Configuration Practice Question
Which TWO statements are true about systemd service unit files? (Choose two.)
⚠ Common exam trap
Many candidates confuse the 'EnvironmentFile=' directive with a non-existent 'EnvFile=', and assume 'forking' is the default service type because many legacy daemons use it, but systemd's default is 'simple'.
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 [Service] section is mandatory for a service unit file.
The [Service] section is mandatory in a systemd service unit file; without it, systemd cannot determine how to manage the service process. This section defines the service type, execution command, and other runtime parameters essential for the unit to function.
