• A. Two
• B. One
• C. Four
• D. Three

Answer: (A)

Redundancy and verifiability are essential when acquiring digital evidence. Using two different data acquisition tools provides independent validation of the captured image. Each tool can handle edge cases differently and may apply different default settings, so producing two separate copies allows you to compare them and catch tool-specific errors. By hashing each image and the original data, you can confirm that the copies are identical to the source and to each other, which strengthens the integrity and defensibility of the evidence in court. Relying on a single tool risks missing data or introducing undetected artifacts. Using more than two tools is usually unnecessary for standard cases and would add time; two strikes the balance between thoroughness and efficiency.
