Background on Legacy Markings and CUI
Legacy markings refer to classification labels used before the implementation of the Controlled Unclassified Information (CUI) Program under DoD Instruction 5200.48.
Documents with legacy markings (such as “For Official Use Only” (FOUO) or “Sensitive But Unclassified” (SBU)) must be reviewed for re-marking or redaction to align with CUI requirements.
When Must Legacy Markings Be Updated?
If the document is retained internally (Answer A - Incorrect): Documents under DoD control do not require immediate re-marking unless they are being shared externally.
If the document is classified as Secret (Answer B - Incorrect): This question is about CUI, not classified information. Secret-level documents follow different marking rules under DoD Manual 5200.01.
If a document is being shared externally (Answer C - Correct):
According to DoD Instruction 5200.48, Section 3.6(a), organizations must review legacy markings before sharing documents outside the organization.
The document must be re-marked in compliance with the CUI Program before dissemination.
If the original document does not contain CUI (Answer D - Incorrect): The original source document's status does not affect the requirement to re-mark a derivative document if it contains CUI.
Conclusion
The correct answer is C: Documents with legacy markings must be re-marked or redacted when being shared outside the organization to comply with DoD CUI guidelines.
