D.
ext2
Answers
D.
ext2
Suggested answer: A

Explanation:

Journaling is a feature that helps maintain the integrity of the filesystem by keeping a record of changes not yet committed to the main file system. This feature is supported by various filesystems, but not all.

Option A: NTFS NTFS (New Technology File System) is a filesystem used by Windows that supports journaling. This makes it resilient to corruption from unexpected shutdowns or crashes by keeping a log of file changes.

Option B: exFAT exFAT (Extended File Allocation Table) does not support journaling. It is optimized for flash drives and large files but lacks advanced features like journaling.

Option C: HFS HFS (Hierarchical File System) is an older filesystem used by Apple. HFS+ (also known as Mac OS Extended) supports journaling, but HFS itself does not.

Option D: ext2 ext2 (Second Extended File System) is a filesystem for Linux that does not support journaling. Its successor, ext3, introduced journaling.
