Which of the following is NOT one of the TSA regulated security areas at an airport?

• A. Sterile Area
• B. AOA
• C. SIDA
• D. Public Parking

Answer: (D)

The concept tested is which areas are under TSA security regulation at airports. Sterile Area, the Air Operations Area (AOA), and the Security Identification Display Area (SIDA) are all access-controlled zones inside the airport security perimeter. The Sterile Area is the part beyond the security checkpoint where only ticketed passengers and authorized staff may enter. The AOA includes aircraft movement areas like runways and ramps and requires proper credentials and escorts. SIDA refers to restricted zones that require an ID badge to access. Public Parking, however, is outside the secured perimeter and generally open to the public, so it’s not one of the TSA-regulated security areas.
