Which area requires an ID badge for entry and is typically considered part of secured zones?

• A. Sterile Area
• B. Outer Perimeter
• C. Public Waiting Area
• D. SIDA

Answer: (D)

SIDA refers to the zones inside an airport where entry is controlled and you must display a valid security badge to gain access. These areas are secured because they handle sensitive operations and passenger flow, so credentials are checked and often tied to a need-to-know basis. The badge you wear proves you’re cleared to be in these spaces, after proper verification. Why this fits best: it names the overall category of access-controlled, secured areas that require a badge to enter. Sterile Areas are examples of SIDA zones, so they do require a badge too, but they’re a subset of the broader SIDA designation. The outer perimeter is the boundary around the secure area and isn’t itself described as a SIDA with badge requirements, while a Public Waiting Area is typically not a secured, badge-controlled space.
