CompTIA A+ Core 1 (220-1101) — Question 453

Which of the following devices is designed to monitor and filter incoming and outgoing network traffic?

Answer options

• A. Switch
• B. Access point
• C. Firewall
• D. Hub

Correct answer: C

Explanation

The Firewall is the correct answer because it is explicitly designed to monitor and filter traffic based on predefined security rules. In contrast, a Switch primarily directs traffic between devices on the same network, an Access Point provides wireless connectivity, and a Hub simply connects multiple devices without any filtering capabilities.
