Canadian Border Security (CBSA) Practice Exam 2025 - Free Practice Questions and Study Guide

One of the main responsibilities of the U.S. Customs and Border Protection (CBP) is to keep terrorists and weapons out of the United States. This task is a critical aspect of national security and involves thorough inspections and screenings at border points, including airports and land borders. By implementing advanced technology and intelligence, CBP works to identify and mitigate threats posed by individuals or groups intending to harm U.S. citizens and interests.

Furthermore, this responsibility encompasses monitoring and controlling the flow of goods and people entering the country to ensure that no dangerous materials or individuals are able to cross the border undetected. This proactive approach helps maintain safety and security within the U.S., illustrating the importance of CBP's role in protecting the nation from potential threats.

While other options mention important functions, they do not encapsulate the primary security-centric mission that defines CBP's core responsibilities. Ensuring the safety of the homeland against terrorism and the smuggling of weapons remains the foremost priority of the agency.
