SK0-004 · Question #693

An administrator is configuring a multi-terabyte storage array for high-speed file access by a Unix system. Which of the following filesystem types would be best for the administrator to implement?

The correct answer is D. ZFS. ZFS is the optimal filesystem for large multi-terabyte Unix storage arrays because it integrates volume management, RAID-Z parity, data checksumming, and high-throughput I/O in a single stack designed for enterprise Unix environments.

Why each option

ZFS is the optimal filesystem for large multi-terabyte Unix storage arrays because it integrates volume management, RAID-Z parity, data checksumming, and high-throughput I/O in a single stack designed for enterprise Unix environments.

AExt2

Ext2 is an older Linux filesystem that lacks journaling and was designed for smaller volumes, making it unsuitable for high-performance multi-terabyte arrays.

BNTFS

NTFS is a Windows-native filesystem; while accessible on Unix via third-party drivers, it is not designed for native Unix high-performance storage and lacks enterprise array features.

CReiserFS

ReiserFS was developed for Linux but has seen stagnant upstream development since the early 2010s and lacks the integrated volume management, checksumming, and scalability that ZFS provides for large arrays.

DZFSCorrect

ZFS (Zettabyte File System), originally developed by Sun Microsystems for Solaris and now available as OpenZFS on Linux and BSD, was purpose-built for massive storage arrays on Unix systems. It provides native support for multi-terabyte volumes with built-in RAID-Z redundancy, end-to-end checksumming for data integrity, copy-on-write snapshots, and high-performance I/O - eliminating the need for a separate volume manager and making it the industry standard for large-scale Unix storage.
