LPIC-1 Devices, Filesystems and FHS Practice Question
Which THREE directories are required by the Filesystem Hierarchy Standard (FHS) to exist on the root filesystem? (Choose three.)
⚠ Common exam trap
It's easy for candidates to confuse commonly present virtual filesystems (like /proc and /sys) with FHS-mandated directories, because they appear on almost every Linux system, but the FHS does not require them to exist on the root filesystem.

Correct answer & explanation
✓
/var
The Filesystem Hierarchy Standard (FHS) mandates that /var, /srv, and /opt must exist on the root filesystem. /var contains variable data such as logs and spools, /srv holds site-specific service data, and /opt is reserved for add-on application software packages. These directories are explicitly listed as required in the FHS specification.
