Which deployment describes internal LAN VPNs connecting two office LANs via the Internet?

• A. Internal LAN VPNs connect two office LANs together via the Internet
• B. District VPNs connect multiple sites via MPLS
• C. VPNs only connect remote workers to a single office
• D. VPNs require dedicated leased lines

Answer: (A)

This item tests understanding of site-to-site VPN deployments. When two office LANs are connected over the Internet, each site has a VPN gateway (router or firewall) that establishes a secure tunnel to the other site. This setup extends the two local networks across the public network as if they were one extended LAN, allowing devices and services at one office to reach the other directly through the encrypted tunnel. This is distinct from remote access VPNs, which are for individual users connecting to a single office from outside, and from MPLS or private leased-line WANs, which rely on different kinds of private networks rather than using the public Internet. So the described deployment—two office LANs linked via the Internet using VPN gateways and a secure tunnel—fits site-to-site (internal LAN) VPN.
