LFCS Storage Management Practice Question
Which THREE of the following are valid Linux filesystem types that can be used for root partitions on a modern Linux system?
⚠ Common exam trap
Test-takers frequently confuse filesystems that Linux can read/write (like NTFS or FAT32) with native Linux filesystems that are suitable for root partitions, or they may overlook that Btrfs, while less common, is fully supported and valid for root on modern distributions.

XFS
XFS is a high-performance 64-bit journaling filesystem created by Silicon Graphics, now widely supported in the Linux kernel. It is a valid choice for root partitions on modern Linux systems, especially for large file and high-concurrency workloads, and is the default filesystem in Red Hat Enterprise Linux 7 and later.
