Which statement accurately describes Residual Data?

Which statement accurately describes Residual Data?

• A. Metadata maintains a record about a document
• B. Archival Data is not commonly used
• C. Residual Data can be retrieved
• D. Transient Data resides in memory

Answer: (C)

Residual data are the traces left on storage media after an action like deletion or erasure, meaning the actual bytes can still exist in places such as unallocated space, slack space, or remnants of deleted files. Because deletion often only marks space as free rather than immediately overwriting it, those bytes can be recovered with forensic tools. That’s why the statement that residual data can be retrieved is the best description. Metadata describes information about a file, not residual traces of the data itself; archival data being not commonly used isn’t a defining trait of residual data, and transient data refers to data in memory, not the persistent remnants on storage media.
