Which VPN type connects two or more networks securely over the Internet?

• A. Site-to-site VPN
• B. Remote-access VPN
• C. Client VPN
• D. VPN tunnel

Answer: (A)

This is about how VPNs connect endpoints: linking entire networks versus individual users. A site-to-site VPN creates encrypted tunnels between gateways at different sites, so the networks themselves are joined over the Internet and traffic between them is securely carried as if they were on the same local network. This approach doesn’t require every device at each site to run VPN software—the edge devices handle encryption and routing for all inter-site traffic. That makes it ideal for connecting two or more networks, such as branch offices or data centers, into a single logical network. Remote-access or client VPNs, by contrast, are meant for individual users connecting from outside to a central network, not for linking networks together. The idea of a VPN tunnel is the secure channel used by these deployments, but the type that connects entire networks is the site-to-site configuration.
