Which Linux file system is known for high scalability and speed with large files?
✗ Incorrect
XFS is designed for high performance and scalability, especially with large files.
What feature do ext4 and XFS share to help protect data integrity?
✗ Incorrect
Both ext4 and XFS use journaling to log changes before writing to disk, protecting data.
Which file system is the default for many Linux distributions due to its balance of performance and stability?
✗ Incorrect
ext4 is the default for many Linux distros because it is stable and performs well.
Delayed allocation in file systems helps to:
✗ Incorrect
Delayed allocation postpones disk block assignment to optimize write performance.
Which file system is typically preferred for server environments handling large data loads?
✗ Incorrect
XFS is preferred in servers for its ability to handle large files and parallel I/O efficiently.
