LPIC-1 Devices, Filesystems and FHS Practice Question

Exhibit

Refer to the exhibit.

$ cat /etc/fstab
# /etc/fstab: static file system information.
UUID=abc123 / ext4 defaults 0 1
UUID=def456 /boot ext4 defaults 0 2
UUID=ghi789 none swap sw 0 0
/dev/sdb1 /mnt/data ext4 defaults 0 0
//192.168.1.100/share /mnt/nfs nfs defaults 0 0

Based on the /etc/fstab entry, which filesystem will be checked by fsck at boot time?

⚠ Common exam trap

Candidates often confuse the dump field (5th column) with the pass field (6th column). fsck at boot only uses the pass field; filesystems with pass=0 (like swap and /mnt/data) are not checked, regardless of the dump field. The order of checking is determined by the pass number (root typically 1, then others with higher numbers).

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

✓

/ and /boot only

The /etc/fstab entry shows that only the root filesystem (/) and /boot have a non-zero value in the pass field (the sixth field). The fsck command at boot time checks filesystems with a pass number greater than 0, and the order is determined by the pass number (root typically 1, /boot 2). Since /mnt/data and swap have a pass value of 0, they are skipped.
