Journaling filesystem with extents and delayed allocation
High-performance 64-bit journaling filesystem
Copy-on-write filesystem with snapshots and compression
Advanced filesystem with volume management and checksumming
Network filesystem for sharing directories over a network
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
ext4: A journaling filesystem that is the default for many Linux distributions, supporting extents and large files.
The correct matches are ext4 (default journaling filesystem), XFS (high-performance parallel I/O), Btrfs (copy-on-write with snapshots), and F2FS (flash-friendly). Common confusions include swapping ext4 with Btrfs and XFS with F2FS.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
ext4: A journaling filesystem that is the default for many Linux distributions, supporting extents and large files.
Why this is correct
ext4 is the default filesystem for many Linux distros, featuring journaling, extents, and support for large files.
ext4: A copy-on-write filesystem with built-in snapshot and compression capabilities.
Why it's wrong here
Incorrect — this describes Btrfs, not ext4.
XFS: A high-performance 64-bit journaling filesystem optimized for parallel I/O and large file support.
Why this is correct
XFS is known for high performance with large files and parallel I/O.
XFS: A flash-friendly filesystem designed for NAND flash storage, minimizing write amplification.
Why it's wrong here
Incorrect — this describes F2FS, not XFS.
Btrfs: A copy-on-write filesystem that provides snapshots, compression, and RAID functionality.
Why this is correct
Btrfs offers advanced features like snapshots, compression, and built-in RAID.
F2FS: A flash-friendly filesystem optimized for NAND flash storage, commonly used on mobile devices.
Why this is correct
F2FS is designed specifically for flash storage to improve performance and longevity.
