LFCS Storage Management Practice Question
An administrator is configuring LVM and wants to display information about physical volumes, volume groups, and logical volumes. Which two commands provide this information? (Choose two.)
⚠ Common exam trap
It's easy for candidates to confuse the 'scan' commands (option A) with 'display' commands, assuming that scanning also shows detailed information, when in fact `pvscan` only lists discovered PVs without showing attributes like PE size or free space.

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
✓
pvdisplay, vgdisplay, lvdisplay
Options D and E are correct because both `pvdisplay`, `vgdisplay`, `lvdisplay` (option D) and `pvs`, `vgs`, `lvs` (option E) are standard LVM commands that display detailed or summary information about physical volumes, volume groups, and logical volumes, respectively. Option D provides verbose output with attributes like PE size, allocation policies, and device paths, while option E offers a compact, customizable tabular view ideal for scripting or quick inspection.
