Question

Quizplus · Accepted Answer

A firewall is specifically designed to prevent unwanted packets from entering a network. It acts as a barrier between a private internal network and the public Internet, controlling and monitoring the traffic that flows in and out of the network. VPN and PPTP are protocols used to establish secure connections over the Internet, while a proxy server is a device or program that acts as an intermediary between a client and a server, typically used for caching and filtering web content. However, none of these components are specifically designed to filter unwanted packets like a firewall.
