Which of the following is a stated responsibility of the Department of Homeland Security?

• A. Guarding against terrorism
• B. Promoting gun rights
• C. Providing free healthcare
• D. Regulating internet content

Answer: (A)

DHS’s role centers on protecting the country from threats and keeping the homeland secure, with preventing terrorism at its core. After 9/11, the department brought together agencies responsible for security, border control, immigration enforcement, critical infrastructure protection, emergency response, and cybersecurity to coordinate these efforts. That focus makes guarding against terrorism a fundamental, stated responsibility.

The other options fall outside DHS’s mission: promoting gun rights is a policy issue tied to advocacy and legislation rather than a security agency’s duty; providing free healthcare is not a DHS function and is handled by health programs and departments; regulating internet content is typically the domain of other regulators like the FCC or justice and cybersecurity agencies, not DHS.
