What is the purpose of the DoD CUI Registry?

• A. An official list of indexes and categories used to identify types of DoD CUI; aligns with DoD issuances
• B. A collection of classified sample documents
• C. A list of DoD personnel authorized to handle CUI
• D. A glossary of acronyms

Answer: (A)

The DoD CUI Registry provides an official catalog of CUI categories and the DoD issuances that define them, serving as the authoritative map for identifying and classifying DoD CUI. By listing the category names, their associated identifiers, and the governing DoD documents, it ensures consistent labeling, handling, and protection across agencies and programs. This alignment with DoD issuances makes it the go-to reference for determining which category applies to a given piece of information and what markings or controls are required.

The other options don’t fit the registry’s purpose. It is not a collection of classified sample documents, nor a roster of personnel who may handle CUI, and it isn’t simply a glossary of acronyms.
