LFCS Service Configuration Practice Question
Which THREE of the following are valid directives for the [Service] section of a systemd unit file?
⚠ Common exam trap
Test-takers frequently confuse `[Unit]` directives (like `Requires`, `Description`, `After`) with `[Service]` directives, leading them to select options that are valid in other sections but not in the `[Service]` block.

Correct answer & explanation
✓
Type
The `Type` directive is valid in the `[Service]` section because it defines the service's process startup type (e.g., `simple`, `forking`, `oneshot`, `dbus`, `notify`, `idle`). This tells systemd how to monitor the service's main process and determine when it has started successfully, which is essential for proper service management.
