LPIC-1 Devices, Filesystems and FHS Practice Question
Exhibit
--- /dev/sda1 on / type ext4 (rw,relatime,errors=remount-ro) /dev/sda2 on /var type ext4 (rw,relatime) /dev/sdb1 on /mnt/backup type ext4 (rw,relatime) /dev/sdc1 on /media/usb type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro) tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime,size=10240k) ---
Refer to the exhibit. Based on the mount options shown, which filesystem is most likely to store filenames with mixed case and support long filenames?
⚠ Common exam trap
LPI often tests the misconception that ext4 filesystems require codepage or utf8 mount options for long filenames, when in fact those options are specific to FAT/VFAT filesystems that need explicit character set handling for backward compatibility with short 8.3 names.
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
✓
/dev/sdc1
The mount options shown for /dev/sdc1 include 'utf8' and 'codepage=437', which are characteristic of VFAT (or FAT32) filesystems. VFAT supports mixed-case filenames (though it is case-insensitive) and long filenames via the VFAT extension, which stores up to 255 UTF-16 characters. The other filesystems are either ext4 (which also supports mixed case and long names but does not use codepage/utf8 options) or tmpfs (which is RAM-based and not typically mounted with such options).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
/dev/sdc1
Why this is correct
Correct. The mount options utf8 and codepage=437 are characteristic of VFAT/FAT32 filesystems, which support mixed-case and long filenames via VFAT extensions.
- ✗
/dev/sda2
Why it's wrong here
Incorrect. This is likely an ext4 filesystem; ext4 does not use codepage or utf8 mount options for long filenames.
- ✗
/dev/sda1
Why it's wrong here
Incorrect. Similar to /dev/sda2, this is also not using VFAT-specific mount options.
- ✗
/dev/sdb1
Why it's wrong here
Incorrect. This is not the filesystem with the VFAT options.
- ✗
tmpfs
Why it's wrong here
Incorrect. tmpfs is a RAM-based filesystem and does not use such mount options.
