How many types of VPN models are commonly classified?

• A. One: traditional VPN
• B. Two: overlay VPN and peer-to-peer VPN
• C. Three: client, server, and hybrid VPN
• D. Four: secure, standard, enterprise, and personal VPN

Answer: (B)

The classification of VPN models into overlay VPN and peer-to-peer VPN is based on their underlying architecture and how they manage data transmission over the internet. Overlay VPNs create a virtual network on top of the existing network infrastructure. They utilize tunneling protocols to encapsulate the data packets, allowing for secure transmission through public networks while maintaining user privacy. This approach is commonly used in enterprise settings where secure access to resources is required without modifying the underlying physical infrastructure. On the other hand, peer-to-peer VPNs establish direct connections between user devices (peers) without needing a central server to manage the connections. This model is often seen in scenarios where decentralized communication is beneficial, such as in file-sharing applications or direct user-to-user communications. This classification effectively captures the main distinctions between how these two types of VPNs operate and fulfill different requirements for security and connectivity. Other choices mention models that may not comprehensively cover the nuanced architectures or combine unrelated concepts and functionalities. Therefore, classifying the VPNs as overlay and peer-to-peer provides a clear and concise understanding of their operational frameworks.
