Answer options

• A. router
• B. switch
• C. load balancer
• D. firewall

Correct answer: D

Explanation

The correct answer is D, firewall, as it specifically monitors and controls traffic based on security rules. A router primarily directs traffic between networks, a switch connects devices within the same network, and a load balancer distributes traffic across multiple servers, none of which focus on security roles.
