If more than ______% of all issued and unexpired media for non-public areas is unaccounted for, what must the airport operator do?

• A. 3%
• B. 5%
• C. 7%
• D. 10%

Answer: (B)

Managing access media for non-public areas is all about accountability and controlling who can enter restricted spaces. When more than a small portion of issued media is unaccounted for, it signals a real security risk because missing credentials could be used to gain unauthorized access. The safe, defined threshold here is five percent. If the number of unaccounted-for media exceeds that level, the airport operator must act promptly to restore control: perform a full inventory of all issued media, revoke or deactivate missing items, reissue credentials as needed, and review and tighten the issuance and deactivation processes to prevent recurrence. In addition, notify the appropriate security authorities and carry out root-cause analysis to implement additional safeguards. A lower threshold like three percent would trigger action sooner but isn’t the standard here, while higher thresholds such as seven or ten percent would permit a larger lapse before taking corrective steps, increasing risk. Five percent is the point that ensures timely, decisive action to maintain security in non-public areas.
