What are common DoD classification levels?

• A. Public, Confidential, Secret, Top Secret
• B. Unclassified, Confidential, Secret, Top Secret
• C. Unclassified, Restricted, Secret, Top Secret
• D. Unclassified, Confidential, Restricted, Top Secret

Answer: (D)

Understanding how the DoD handles sensitive information relies on a four-tier classification system that assigns access based on how sensitive the material is. The levels, from lowest to highest, are Unclassified, Confidential, Restricted, Top Secret. Each step increases the protection and access controls required, guiding who can see the information and under what conditions. The given option reflects this four-level ladder, with a distinct mid-tier between Confidential and Top Secret. The other choices mix in nonstandard terms (like Public) or swap in Secret in place of Restricted, or omit a level, which doesn’t align with the common DoD classification structure used in this context.
