What is the AFF4 object that stores indivisible blocks of data?

1. Volume

2. Segment

3. File

4. Repository

The correct answer is: Volume

The correct answer is Segment. In the context of the Advanced Forensics Format (AFF4), a segment is the object that stores indivisible blocks of data. Segments are designed to effectively manage data integrity and support efficient reading and writing processes. They are the building blocks of the AFF4 structure, allowing for stable, manageable data storage that can represent complex file systems or disk images. While a volume typically refers to a larger storage unit that can encompass multiple segments, segments themselves ensure that the data is divided into manageable pieces that can be independently accessed, making data handling more efficient. The concept of a repository relates to a broader collection of forensic data but does not specify how the data is divided or accessed. A file, in this context, is usually seen as a higher-level object used for user-accessible data, as opposed to the underlying structure and data management provided by segments.
