CompTIA DataSys+ (DS0-001) — Question 9

Which of the following firewall types allows an administrator to control traffic and make decisions based on factors such as connection information and data flow communications?

Answer options

• A. Circuit-level
• B. Stateful
• C. Proxy
• D. Packet

Correct answer: B

Explanation

The correct answer is B, Stateful, because it tracks the state of active connections and makes decisions based on the context of traffic flow. In contrast, A (Circuit-level) only monitors connection establishments, C (Proxy) acts as an intermediary, and D (Packet) analyzes packets without keeping track of connection states.
