Which of the following is NOT part of ALCOA+ data integrity attributes?

• A. Attributable, Legible, Contemporaneous, Original
• B. Accurate, Complete, Consistent, Enduring
• C. Available, Traceable, Unaltered
• D. All of the above are ALCOA+ attributes

Answer: (C)

ALCOA+ data integrity focuses on ensuring data can be trusted from creation through archiving, with attributes that cover who created it, when, and how it can be found and verified. The familiar set includes Attributable, Legible, Contemporaneous, Original, and the + extensions Accurate, Complete, Consistent, Enduring, Available, and Traceable.

This option lists two valid ALCOA+ attributes—Available and Traceable—but uses a term not typically part of the standard list: Unaltered. The formal attributes map Original to the idea of being unaltered in spirit, but “Unaltered” itself isn’t an official ALCOA+ attribute name. Since one element in this grouping isn’t part of the recognized ALCOA+ terminology, this option is the one that does not fit the established set.
