Which file system introduces permissions, encryption, and disk quotas?

  1. FAT 32

  2. exFAT

  3. NTFS

  4. ext4

The correct answer is: NTFS

NTFS is the recommended file system for Windows based operating systems and it offers advanced features such as permissions, encryption, and disk quotas. FAT 32, exFAT, and ext4 do not offer these features. FAT 32 and exFAT are older file systems that do not support these advanced features and are primarily used for external storage devices. ext4 is a file system commonly used in Linux operating systems, which also does not have these advanced features. Therefore, NTFS is the correct answer as it is the only file system mentioned that introduces permissions, encryption, and disk quotas.
