Which statement about a steganographic file system is accurate?

• A. It stores files by hiding data within the file system without others' knowledge
• B. It encrypts data only at rest
• C. It compresses data for storage efficiency
• D. It duplicates data across drives

Answer: (A)

The main idea being tested is concealment of data within the file system so its existence isn’t evident. A steganographic file system stores files by embedding or hiding their data inside the file system itself in a way that isn’t obvious to others. This means the data exists, but there’s no obvious sign of it just by looking at standard file system structures. It’s different from encryption, which only disguises the content of data but not the fact that data is present; it’s also not about compression or duplicating data across drives, which relate to size or redundancy, not concealment. So the statement that a steganographic file system hides data within the file system so others don’t know it’s there correctly captures the concept.
