Under the Clinger-Cohen Act, which of the following describes a National Security System?

• A. Involves intelligence activities
• B. Involves patient health records
• C. Involves civilian email
• D. Involves public website hosting

Answer: (A)

The main idea here is how the Clinger-Cohen Act defines a National Security System: it consists of information systems used or operated by or for federal agencies that are involved in intelligence activities. That direct link to intelligence work is what makes a system fall under NSS.

So, choosing that it involves intelligence activities is best because it matches the act’s criterion for NSS—systems that process, transmit, or support intelligence and national security missions. The other options describe systems that are not inherently tied to national security or intelligence work (health records, civilian email, public website hosting), so they don’t meet the NSS definition.
