CompTIA A+ Core 2 (220-1202)Operating SystemsMedium
A technician is tasked with creating a new Linux server that will host a web application. The server needs to handle frequent read/write operations efficiently, support large file sizes, and provide robust journaling capabilities for data integrity. Which Linux file system is generally recommended for such a scenario?
- AFAT32
- BNTFS
- CAPFS
- Dext4
Show answer & explanationAnswer & explanation
Correct answer: D. ext4
ext4 (Extended File System 4) is the default and most widely used journaling file system for Linux distributions. It offers excellent performance, supports large file sizes, and provides robust journaling for data integrity, making it ideal for server environments.
Why the other options are wrong
- A. FAT32 is an older file system with limitations on file size (4 GB) and lacks journaling and robust permissions, making it unsuitable for a Linux server.
- B. NTFS is primarily a Windows file system and is not natively supported or recommended as the primary file system for a Linux server.
- C. APFS is Apple's file system and is not used in Linux environments.
ext4 (Extended File System 4)
The current default file system for many Linux distributions, offering improved performance, scalability, and reliability over its predecessors, ext2 and ext3, primarily through journaling.
- Supports file sizes up to 16 TB and volume sizes up to 1 EB.
- Uses journaling for quick recovery after system crashes.
- Backward compatible with ext2 and ext3.
Memory trick: EXT4 is 'EXcellent' for Linux.
