What step occurs right after the person clears the threshold of the first gate in the sally port operation?

• A. Open the second gate
• B. Search the person or vehicle
• C. Close the first gate
• D. Record the movement in a log

Answer: (C)

In a sally port, two doors create a secure, controlled space between them. The moment someone clears the threshold of the first gate, the immediate step is to close that gate. This seals off the outside and maintains a protected pocket where screening or other security checks can occur before the second gate is allowed to open. Opening the second gate right away would bypass the protective barrier the first gate provides. Usually, the actual search or screening happens inside the secured area after the first gate is closed, and logging the movement is part of the post-entry process rather than the immediate next action. So the best answer is to close the first gate.
