Partly checked. None of the 76 questions here has been read against the cited source by a person. 75 questions have been checked against their cited clause by an automated pass — which is not the same thing, and is not a signature.
1 question has had neither check. It is written from the published exam objectives and cite the clause it comes from, but it is kept out of search results and out of mock exams until someone has looked. It is here to be read and challenged, not to be trusted.
Only questions a person has signed for are used in mock exams here. That is the whole difference between the two kinds of checking above.
How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.
What this objective covers
The 76 questions written for this objective cite 6 LPI exam objectives (104.1, 104.2, 104.3, 104.5, 104.6, 104.7) and 28 manual pages (bash(1), chmod(1), chown(1), df(1), e2fsck(8), fdisk(8), find(1), fsck(8), gdisk(8), hier(7), ln(1), ls(1), lsblk(8), mke2fs(8), mkfs.btrfs(8), mount(8), parted(8), path_resolution(7), readlink(1), swapon(8), symlink(7), systemd.mount(5), umount(8), unlink(2), updatedb.conf(5), whereis(1), xfs_fsr(8), xfs_repair(8)).
They break down as 51 single-answer questions, 12 choose-several questions and 13 type-the-answer questions.

Questions on this objective (page 2 of 4)
- Select the THREE true statements about the special permission bits on Linux. machine-checked
- Select the TWO file placements that follow the Filesystem Hierarchy Standard. machine-checked
- `umount /mnt/data` fails with 'target is busy'. Select the TWO commands that help you find out which processes are keeping it busy. machine-checked
- Type the complete command that creates an ext4 filesystem on the partition /dev/sdb1, using default options. machine-checked
- The partition /dev/sdb2 has been set aside for paging. Type the command that prepares it as a swap area (it does not activate it). machine-checked
- You want every regular file a shell creates to come out as rw-r----- (640) and every new directory as rwxr-x--- (750). Type the complete command that sets that default. machine-checked
- locate cannot find a file you created a few minutes ago. Type the command, run as root, that rebuilds the database locate searches. machine-checked
- Type the complete command that creates a symbolic link at /usr/local/bin/python pointing to the existing executable /usr/bin/python3.11. machine-checked
- Type the command that reports the total disk space consumed by /var/log including everything beneath it, as one single human-readable figure. machine-checked
- A 4 TB disk /dev/sdb carries an MBR partition table with data you must keep, and you need it converted to GPT in place so that the whole disk becomes usable. Which interactive tool is built to do that conversion? machine-checked
- You partition a 4 TB disk with an MBR partition table and find that, however you arrange the partitions, about half the disk cannot be addressed. Which property of the MBR scheme causes that ceiling? machine-checked
- Two empty disks, /dev/sdc and /dev/sdd, are to hold a single Btrfs filesystem that keeps a mirrored copy of both data and metadata across the pair, using Btrfs's own multi-device support. Which command creates it? machine-checked
- You want a quick inventory of every disk the system can see, with its size and partition table, printed to the terminal without entering any interactive editor. Type the complete fdisk command line, including its option, that does this. machine-checked
- Which THREE of the following tools create or modify a partition table on a disk? (Choose three.) machine-checked
- A mail server writes thousands of tiny files into /var/spool. Deliveries start failing with 'No space left on device', yet `df -h /var/spool` shows the filesystem is only 40% full. Which command confirms the real cause? machine-checked
- An XFS filesystem that has held constantly appended log files for two years has become badly fragmented. Which command reorganises the files to reduce fragmentation while the filesystem stays mounted and in use? machine-checked
- A server has dropped into a maintenance shell because the unmounted ext4 filesystem on /dev/sdb1 has errors. You want the check to run unattended, answering yes to every question it asks. Which command does that? machine-checked
- e2fsck refuses to check /dev/sdb1, reporting that the superblock is corrupt or has a bad magic number. You know a backup superblock sits at block 32768. Which command restarts the check from that copy? machine-checked
- Before a maintenance window you want to know whether the unmounted XFS filesystem on /dev/sdb1 is damaged, without letting anything be modified. Type the complete command that checks it and reports what it would do, in no-modify mode. machine-checked
- An /etc/fstab entry for an ext4 data partition carries the single word `defaults` in its fourth field. Which set of mount options does that keyword stand for? machine-checked
