Which file system was explicitly described as 128-bit and designed to protect against data corruption?

• A. NTFS
• B. UFS
• C. ZFS
• D. FAT

Answer: (C)

Protecting data against corruption through end-to-end integrity checks and a copy-on-write design is what sets this file system apart. It uses 128-bit block pointers and per-block checksums so every piece of data can be verified, and writes don’t overwrite existing data until a new copy is safely stored. When redundancy (like mirrors or RAID-Z) is available, corrupted blocks can be automatically repaired during scrubs, giving true self-healing capabilities. This explicit focus on robust data integrity is what makes it the best choice for protecting against data corruption, unlike NTFS, UFS, or FAT, which do not provide the same built-in, end-to-end integrity and self-healing features.
