Which item is required beyond standard ID for unescorted NAOC entry?

• A. RAB with open area 18
• B. Additional ID verification
• C. Both A and B
• D. Background check

Answer: (C)

For unescorted NAOC entry, you need a layered verification beyond standard ID. The RAB with open area 18 confirms you’re authorized to access that specific area, while additional ID verification strengthens identity confirmation to prevent impersonation. Relying on either measure alone leaves a gap: you could have area access without verifying who you are, or you could verify identity without proving you’re cleared for that area. Together, they meet the security requirement for unescorted entry. Background checks by themselves don’t fulfill the immediate access needs for unescorted NAOC entry, so both the RAB designation and the extra ID check are necessary.
