STEPP Marking Classified Information Practice Exam 2026 - Free Classified Information Practice Questions and Study Guide

The reference to 10 C.F.R Part 1045 is significant as it pertains specifically to the classification and protection of nuclear information and materials in the United States. This regulation outlines the requirements for the control of classified information related to atomic energy, detailing how information should be classified, marked, and handled to ensure national security.

In contrast, while Department of Energy Regulations might cover a broader spectrum of issues related to energy, they may not provide as specific a focus on nuclear classification as 10 C.F.R Part 1045. NATO Guidelines, likewise, address security protocols concerning member nations but do not specifically delineate the classification standards for nuclear information. National Security Agency Protocols focus on signals intelligence and cybersecurity rather than nuclear classification. Therefore, referencing 10 C.F.R Part 1045 is the most appropriate and targeted choice for information regarding nuclear classification.
