Which of the following is a primary relationship for an ACS?

• A. Public Health Officer
• B. FBI Airport Liaison Agent
• C. Tourism Board Member
• D. Airport Ground Crew Supervisor

Answer: (B)

The key idea is who coordinates major security incidents and threat information at an airport. An FBI Airport Liaison Agent serves as the formal bridge between federal law enforcement and airport operations, enabling rapid sharing of intelligence, joint investigations, and access to federal resources during security events. This makes them the primary relationship for an ACS, since timely, authoritative coordination with national security authorities is essential.

A Public Health Officer handles health-related responses, which are important but not the primary channel for security incident coordination. A Tourism Board Member is focused on promoting the destination rather than incident management. An Airport Ground Crew Supervisor oversees day-to-day ground operations and safety, but does not serve as the main link to federal security leadership.
