CompTIA Tech+ FC0-U71 Practice Question

A firewall is the correct answer because it is specifically designed to monitor and control incoming and outgoing network traffic based on security rules. This would prevent unauthorized access to internal resources. A switch primarily connects devices within a network and manages data flows between them. A router is used to connect multiple networks and route traffic between them. An access point allows wireless devices to connect to a wired network, but it does not regulate traffic with security rules.
