LPIC-1 Devices, Filesystems and FHS Practice Question
Which THREE of the following directories are part of the FHS and must be present on a standard Linux system? (Choose three.)
⚠ Common exam trap
The trap here is that /lost+found appears essential because it is commonly seen on ext filesystems, but it is not part of the FHS mandatory list, and /home is often assumed required due to its ubiquity, yet the FHS does not mandate it for a standard Linux system.

Correct answer & explanation
✓
/var
/var is required by the FHS to store variable data such as logs (/var/log), mail spools, and print queues. It must exist on a standard Linux system because many core services depend on it for runtime data that changes in size and content.
