Which of the following filesystems supports journaling?

The correct response indicates ext3 as a journaling filesystem. Journaling is a feature that helps protect data integrity by keeping track of changes not yet committed to the file system. In the event of a system crash or power failure, journaling can help in recovering the file system quickly and consistently.

Ext3, which stands for third extended filesystem, builds on its predecessor ext2 by adding journaling capabilities. This allows ext3 to log changes in a journal before they are made to the main file system. If the system crashes during an operation, the journaling process helps to ensure that the file system can be repaired more efficiently by replaying the journal and restoring it to a consistent state.

While XFS also supports journaling and is well-known for handling large files and scalability, the question specifies ext3 directly as the correct answer. FAT32, on the other hand, does not support journaling, which makes it less robust in terms of data integrity compared to journaling filesystems. NTFS does offer journaling, but within the context of traditional Linux filesystems, ext3 is often recognized specifically for its compatibility and typical use in Linux environments. Therefore, identifying ext3 as the correct answer highlights its specific role in journaling among commonly used
