Which statement describes NTFS versus ext4?

• A. NTFS supports rich metadata and security features; ext4 uses Linux permissions and is journaling.
• B. ext4 supports rich metadata and security features; NTFS uses Linux permissions.
• C. Both have identical features.
• D. NTFS and ext4 are not used in any modern systems.

Answer: (A)

NTFS and ext4 are designed around different operating system models, so they differ in how they handle security, permissions, and metadata. NTFS, used by Windows, provides rich metadata and security features through mechanisms like access control lists (ACLs) and built-in encryption, aligning with Windows’ security framework. Ext4, used by Linux, relies on Linux-style permissions (owner, group, others) and supports POSIX ACLs, along with its own robust metadata features, and it is a journaling file system to help recover from crashes. This combination—NTFS offering rich metadata and security features, and ext4 using Linux-style permissions with journaling—best captures the typical differences between these two file systems.
