The installation image /srv/iso/debian.iso must be inspected without burning it. The directory /mnt/iso already exists. Type the complete command that mounts the image there, requesting the loop device with a mount option.
LPIC-1 Exam 101-500, objective 104. Devices, Linux filesystems, filesystem hierarchy standard hard
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.
Answer
Type the answer.

mount -o loop /srv/iso/debian.iso /mnt/isomount -o loop /srv/iso/debian.iso /mnt/iso/mount --options loop /srv/iso/debian.iso /mnt/isomount --options=loop /srv/iso/debian.iso /mnt/isomount -o loop -t iso9660 /srv/iso/debian.iso /mnt/isomount -t iso9660 -o loop /srv/iso/debian.iso /mnt/iso
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
A filesystem image held in a regular file has no block device of its own, so the kernel needs a loop device to present the file as one. The loop mount option makes mount find a free /dev/loopN and set it up automatically, which is why losetup is rarely needed by hand any more. The filesystem type may be left out because mount probes it (iso9660 here), and an ISO is mounted read-only whether or not ro is given.

Practise this
Reading one question is not practice. The trainer will draw a short set from objective 104 and space the ones you get wrong.

- A new disk /dev/sdb has no partition table at all. Which command writes an empty GPT partition table onto it without dropping you into an interactive editor? machine-checked
- You need the partition /dev/sdc1 on a USB stick to carry a FAT32 filesystem so that Windows machines can read and write it. Which command creates it? machine-checked
- You have just run `mkswap /dev/sdb2`. Which command makes the kernel start using that swap area immediately, without a reboot? machine-checked
- Why is it dangerous to run e2fsck against an ext4 filesystem that is currently mounted read-write? machine-checked
- On an ext4 filesystem at /dev/sda1 you want an automatic check to be forced after every 30 mounts. Which command sets that? machine-checked
- `df -h /var` reports the filesystem 100% full, but `du -sh /var` accounts for only about half that space. Nothing is hidden under a mount point. What is the most likely explanation? machine-checked
