What term describes the step beyond data destruction that verifies data has been wiped and is no longer accessible?

• A. Data Archiving
• B. Data Handling
• C. Data Purge
• D. Data Sanitization

Answer: (D)

The main idea is the verification step that ensures a data wipe really worked and that no data remains accessible. This is data sanitization. It goes beyond simply erasing or destroying data by incorporating the processes and checks that confirm the storage medium is securely cleaned and that recovery is not possible. In practice, sanitization combines the wiping with validation—tests or evidence showing that remnants can’t be recovered, often following established standards.

Other terms don’t fit the exact idea here. Data archiving is about keeping data for long-term storage, not about removing it securely. Data handling is a broad term for managing data throughout its lifecycle, not specifically about verifying a wipe. Data purge describes removing data, but sanitization emphasizes the verification that the data is no longer accessible.
