LPIC-1 Devices, Filesystems and FHS Practice Question
A technician is preparing a USB stick that must be readable by both Linux and Windows systems without installing extra drivers. Which filesystem should be created on the stick?
⚠ Common exam trap
The trap here is reaching for a feature-rich Linux filesystem like ext4 or Btrfs when portability to Windows, not advanced features, is the actual requirement.
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
✓
exFAT
A USB stick shared between Linux and Windows needs a filesystem both operating systems understand out of the box. exFAT satisfies this: Windows supports it natively, current Linux kernels include an exFAT driver, and unlike FAT32 it does not impose a 4 GB file size ceiling. The Linux-native filesystems ext4, XFS, and Btrfs all require extra software on Windows, so they fail the cross-platform condition.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
ext4
Why it's wrong here
ext4 is the native Linux filesystem and is not natively readable by Windows, which requires third-party drivers or tools to access it. Creating ext4 would satisfy Linux but fail the cross-platform requirement stated in the scenario. It also stores POSIX permissions and ownership that Windows cannot interpret, making it a poor choice for a portable, shareable USB stick.
- ✗
XFS
Why it's wrong here
XFS is a high-performance Linux filesystem designed for large files and parallel I/O, but Windows has no native support for it. It cannot be mounted on a default Windows installation, so it fails the requirement that the stick be readable on both platforms. Like ext4, it also carries Unix ownership and permission semantics that are irrelevant and unsupported on Windows.
- ✗
Btrfs
Why it's wrong here
Btrfs offers snapshots, checksums, and subvolumes, but Windows cannot read it natively. It is also a copy-on-write filesystem whose features are unnecessary on a removable stick and whose tools are Linux-specific. Choosing it would mean the Windows side cannot access the data without third-party utilities, violating the cross-platform requirement.
- ✓
exFAT
Why this is correct
exFAT is supported natively by Windows and by modern Linux kernels through the exfat driver, and it has no 4 GB per-file limit like FAT32. It stores no Unix permissions, which is acceptable for a portable data stick. This makes it the practical choice when a device must move between Linux and Windows without installing additional software on either side.
