Which term identifies a piece of data under a subcategory of a classification?

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

Answer: (A)

Tagging data with a data tag ties the data to a specific subcategory within a classification by attaching metadata that records its category and sensitivity. This tagging acts as a label the system can read to apply the correct access controls and handling rules, ensuring the data is treated according to its precise subcategory. Data format describes how data is encoded or structured, not its classification subcategory. Deidentification removes personal identifiers, not labels about where the data fits in a classification scheme. Declassification changes the overall sensitivity level, but again doesn’t attach a subcategory label to the data.
