An OSC plans to bid for a DoD contract to supply laser welding services to repair a fleet of unmanned aerial vehicles (UAVs). This requires them to be CMMC Level 2 certified since the information they will receive from the DoD is Controlled Technical Information (CTI). However, their repair and welding services require a Computer Numerical Control (CNC) machine to fabricate some crucial parts. Since the welding is mainly automated using robots, the OSC has intelligently integrated its SCADA system with Programmable Logic Controllers (PLCs) for increased accuracy, improved safety and efficiency, and enhanced flexibility. If the OSC wins the contract, how will the banner marking on documents containing CUI from the DoD be structured?

Answer options

Correct Answer:

Explanation

The structure of a CUI banner marking is dictated by 32 CFR Part 2002 and DoD Instruction 5200.48. The banner begins with the control marking "CUI," followed by a double forward slash ("//"). Controlled Technical Information (CTI) is designated as a "Specified" CUI category, meaning its handling is prescribed by a specific law, regulation, or government-wide policy. Specified categories must be prefixed with "SP-". Therefore, the correct banner marking for a document containing only CTI is "CUI//SP-CTI." The technical details regarding SCADA, PLCs, and CNC machines are irrelevant to the CUI marking requirements.

Why Incorrect

B. CUI//CTI: This is incorrect because it omits the mandatory "SP-" prefix required for Controlled Technical Information, which is a "Specified" CUI category.

C. CUI/SP-CTI: This is incorrect because it uses a single forward slash ("/") instead of the required double forward slash ("//") to separate the control marking from the category marking.

D. CUI-SP//CTI: This is incorrect because the "SP-" prefix must precede the category marking (CTI), not be appended to the control marking (CUI).

This source is the definitive authority for CUI categories and their markings. (Accessed at: https://www.archives.gov/cui/registry/category-detail/controlled-technical-info.html)

2. DoD Instruction 5200.48, "Controlled Unclassified Information (CUI)," March 6, 2020. Section 3.4.a.(1) specifies the banner marking format: "The banner marking will include 'CUI' or 'CONTROLLED' as the control marking, followed by a double forward slash ('//'), and then the CUI category or subcategory markings..." This confirms the use of "//" as the primary separator.

3. 32 CFR § 2002.14, "Marking." This regulation, which governs the entire CUI program, states in paragraph (c)(2) that banner markings may include CUI category markings. The associated NARA CUI Marking Handbook clarifies that "Specified" categories are designated with an "SP-" prefix in the banner.
