A system administrator is setting up a new Linux server that will act as a web server and file server. The administrator needs a file system that supports journaling, large file sizes, and is widely compatible with most Linux distributions. Which file system best meets these requirements?
- Aext4
- BFAT32
- CAPFS
- DNTFS
Show answer & explanationAnswer & explanation
Correct answer: A. ext4
ext4 is the default and most widely used journaling file system for Linux distributions. It supports large file sizes and volumes, providing robust data integrity suitable for servers.
Why the other options are wrong
- B. FAT32 is an older file system with limited file size and partition size support, and no journaling.
- C. APFS is Apple's proprietary file system, not compatible with Linux.
- D. NTFS is Microsoft's proprietary file system, primarily used on Windows, with limited native Linux support.
ext4 File System
The fourth extended filesystem (ext4) is a journaling file system for Linux, widely used as the default for many distributions.
- Supports very large file sizes (up to 16 TiB) and volume sizes (up to 1 EiB).
- Offers journaling for improved data integrity and faster recovery after crashes.
- Backward compatible with ext2 and ext3.
Memory trick: Linux Needs Excellent File System for Robust Tasks.
