LPIC-1 /mnt Practice Question
Which THREE directories are commonly used for mounting removable media in Linux?
⚠ Common exam trap
Candidates may incorrectly assume that /dev (the device directory) is a mount point, or that /mount is a valid FHS directory. They might also overlook /cdrom as a common mount point for optical media, often symlinked to /media/cdrom. The correct mount point directories for removable media per FHS are /mnt (temporary manual mounts) and /media (automatic mounting), with /cdrom being a widely used legacy or symlink location.
Answer choices
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
✓
/mnt
Option A, /mnt, is correct because it is the traditional Filesystem Hierarchy Standard (FHS) mount point for temporarily mounted filesystems, including removable media such as USB drives and external disks. Option C, /cdrom, is correct because it is a conventional mount point historically used by distributions to mount optical media like CD-ROMs and DVDs. Option E, /media, is correct because modern Linux distributions use it as the standard mount point for automatically mounted removable media such as USB sticks, cameras, and optical discs. Option B, /mount, is not a standard FHS directory and is not used by Linux for mounting removable media. Option D, /dev, is incorrect because it contains device files (e.g., /dev/sdb1) that represent hardware devices, not directories where filesystems are mounted.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
/mnt
Why this is correct
/mnt serves as the conventional mount point for temporarily mounted filesystems, including removable media such as USB drives and optical discs. It satisfies the question's requirement for a standard directory used for removable media mounting, distinct from /media, which desktop environments typically manage automatically for user-mounted devices.
- ✗
/mount
Why it's wrong here
/mount is not a standard Linux directory; removable media are conventionally mounted under /mnt, /media or /run/media. It is tempting because the name suggests mounting, but no distribution creates it by default for that purpose.
- ✓
/cdrom
Why this is correct
/cdrom is a conventional mount point for optical media, satisfying the stem's requirement for a removable-media directory. Distributions such as Debian historically created it for CD-ROM drives, and it remains a standard location alongside /media and /mnt for mounting removable devices.
- ✗
/dev
Why it's wrong here
/dev holds device nodes such as /dev/sdb1, not mount points; you mount a filesystem from there onto a directory elsewhere. It is tempting because removable media appear as devices, but /mnt, /media and /run/media are the conventional mount directories.
- ✓
/media
Why this is correct
/media is the standard mount point for removable media on modern Linux systems, satisfying the stem's requirement for a common removable-media directory. The kernel and udev automatically create per-device subdirectories here, such as /media/username/USB_LABEL, when hotplug events are detected.
