What is the purpose of a Data Tag?

• A. Data format
• B. Deidentification
• C. Declassification
• D. Data Tag

Answer: (D)

Tagging data with metadata is used to indicate how it should be handled, who may access it, how long it should be kept, and what protections apply. This labeling lets security and data governance systems automatically enforce policies, apply encryption, restrict access, or route data for appropriate processing based on its classification or other attributes. For example, a document marked as confidential may trigger restricted access and mandatory encryption, ensuring only authorized users can view it. This is not about changing the data’s format, removing identifiers, or lowering its classification; it’s about attaching labels that guide how the data is protected and managed throughout its lifecycle.
