What security questions would a check in agent be expected to ask a passenger?

A check-in agent might ask security questions such as, "Can you please provide a valid form of identification?" and "Have you packed your own bags, and did anyone give you anything to carry?" They may also inquire if the passenger is aware of any prohibited items in their luggage and confirm the traveler's itinerary details for verification. These questions help ensure the safety and security of all passengers.
