A server has multiple disks, and the administrator wants to monitor the health of all disks and receive alerts if any disk is predicted to fail. The administrator plans to run a script daily. Which command should be used in the script to check the health of all disks?

for disk in $(lsblk -d -o NAME | tail -n +2); do smartctl -H /dev/$disk; done

Why is maintaining filesystem integrity important for a Linux system?

It automatically backs up all user data to external storage.

It improves network throughput and reduces latency.

It ensures data consistency and prevents data loss or corruption.

It prevents unauthorized users from accessing the system.

A Linux administrator suspects filesystem corruption on an ext4 partition mounted at /data. The system is currently running and the partition is in use. The administrator needs to check and repair the filesystem with minimal disruption. Which approach should be taken?

Run tune2fs -c 1 /dev/sdb1 and reboot the system.

Run fsck -f /dev/sdb1 while the filesystem is mounted.

Run e2fsck -p /dev/sdb1 while the filesystem is mounted.

Unmount /data, then run fsck -f /dev/sdb1.

An XFS filesystem on /dev/mapper/vg0-lv0 is corrupted and cannot be mounted. The administrator has a backup of the superblock at block 32. Which command should be used to repair the filesystem using this backup superblock?

xfs_repair -L /dev/mapper/vg0-lv0

xfs_repair -b 32 /dev/mapper/vg0-lv0

xfs_repair -n /dev/mapper/vg0-lv0

xfs_repair -f /dev/mapper/vg0-lv0

Part of the Topic 104: Devices, Linux Filesystems, Filesystem Hierarchy Standard domain, which makes up ~14% of our current practice bank. Linux Professional Institute does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–8 in this domain), expect 1–1 from this objective — we provide 14 practice questions to prepare you well beyond it.
