A Visitor Register must be maintained in accordance with which directive, and for how long?

• A. NTP-4; minimum of two years
• B. CMS-5; six months
• C. COMDTINST M5260.3; five years
• D. S2241.5; one year

Answer: (A)

Documenting who enters a facility is a records-keeping task designed for security and accountability. The directive that governs this and the required retention is NTP-4, which specifies that a Visitor Register must be kept for a minimum of two years. This two-year window provides a practical period for security reviews, incident investigations, and audits while keeping the records manageable.

The other options don’t fit because their directives either don’t cover visitor registers or prescribe different retention periods (six months, five years, or one year) that don’t align with the standard practice for this type of record.
