Which filesystem stores a file with two data streams, called NTFS data streams, along with the file attributes?

• A. FAT32
• B. exFAT
• C. ext4
• D. NTFS

Answer: (D)

NTFS supports alternate data streams. A file can have multiple data streams attached to it—the primary stream with the main content plus additional named streams for extra data. NTFS stores this alongside the file’s attributes within its metadata structure (the Master File Table). This combination of multiple data streams plus attributes is a hallmark of NTFS, which is why the correct choice is NTFS. Other file systems don’t implement NTFS-style alternate data streams (FAT32 and exFAT lack ADS), and while ext4 has its own metadata features like extended attributes, they operate differently from NTFS data streams.
