Question
Following a cybercrime incident, a forensic investigator is conducting a detailed examination of a suspect's digital device. The investigator needs to preserve and analyze the disk images without being restricted by various image file formats tied to commercial software, which may limit the investigator's ability to work with a range of analysis platforms. The investigator chooses a simple, straightforward, and uncompressed format that can be easily accessed and analyzed using a wide range of forensic tools and platforms, without the need for specialized software. Which data acquisition format should the investigator use in this case?
Options
- AAdopt the raw format that is commonly used in digital evidence investigations.
- BChoose the AFF4 format, which offers advanced features for comprehensive analysis.
- CEmploy the advanced forensics format for storing metadata and disk images.
- DUse a proprietary format that is compatible with specific commercial software.

Explanation
This question maps directly to CHFI v11 objectives under Data Acquisition and Duplication and Data Acquisition Formats. CHFI v11 clearly explains that the RAW (dd) image format is the most widely used and universally supported forensic image format. RAW images are exact bit-by-bit copies of storage media and do not rely on proprietary structures, compression, or vendor- specific software. This makes them ideal when investigators require maximum compatibility across multiple forensic tools and platforms. The RAW format is simple, uncompressed, and transparent, allowing it to be analyzed by nearly all forensic suites such as Autopsy, FTK, EnCase, and The Sleuth Kit. CHFI v11 emphasizes that RAW images are preferred when long-term accessibility, court admissibility, and tool independence are critical requirements.
