LPIC-1 Devices, Filesystems and FHS Practice Question
Which TWO statements about udev rules are correct? (Choose two.)
⚠ Common exam trap
Many exam-takers confuse 'udevadm verify' with a real command, but the LPIC-1 exam tests knowledge of the actual udevadm subcommands, and 'verify' is not one of them.

Correct answer & explanation
✓
Custom udev rules should be placed in /etc/udev/rules.d/.
Custom udev rules are placed in /etc/udev/rules.d/ to override or supplement the default rules in /lib/udev/rules.d/. This directory is the standard location for system administrators to add persistent device naming or custom actions without modifying distribution-provided files.
