A forensic scientist is examining a computer for possible evidence of a cybercrime. Why should the forensic scientist copy files at the bit level instead of the OS level when copying files from the computer to a forensic computer?
Correct Answer: A
Comprehensive and Detailed Explanation From Exact Extract: Bit-level (or bit-stream) copying captures every bit on the storage media, including files, deleted files, slack space (unused space within a cluster), and unallocated space. This ensures all digital evidence, including artifacts not visible at the OS level, is preserved for analysis. * Copying at the OS level captures only allocated files visible in the file system, missing deleted files and slack space. * Bit-level copying is a cornerstone of forensic best practices as specified in NIST SP 800-86 and SWGDE guidelines. * Timestamp changes and unnecessary information issues are secondary concerns compared to the completeness of evidence.
