• A. Disk-to-disk clone
• B. Disk-to-image file copy
• C. File-by-file copy
• D. Live acquisition

Answer: (B)

The key idea is to preserve evidence with a forensically sound image that can be independently verified in court. A disk-to-image file copy yields a bit-for-bit copy of the entire drive, including unallocated space and metadata, and it’s saved as a single image file (or a set of image files) that you can hash to prove integrity and use for repeatable analysis. This approach supports chain-of-custody documentation and lets your findings be reviewed on any compatible forensic tool without needing the original hardware. A disk-to-disk clone duplicates the drive but ties the evidence to specific hardware, which can complicate sharing, verification, and presentation as a standalone artifact. A file-by-file copy only preserves accessible files and misses deleted data and the surrounding metadata that allow proper reconstruction and verification. Live acquisition captures data while the system is running, which can alter information and is generally less defensible as a complete, unmodified snapshot. So, disk-to-image file copy best protects the integrity, completeness, and portability of the evidence for courtroom use.
