A host is accessing a Web server on a remote network. Which three functions are performed by intermediary network devices during this conversation?

Intermediary network devices perform several key functions during the communication between a host and a remote web server. First, they route data packets by determining the best path for transmission through the network. Second, they may provide network security by filtering traffic, preventing unauthorized access, and mitigating threats. Lastly, they can manage traffic congestion and ensure quality of service by prioritizing data packets based on their type or importance.
