Which term describes a secure method for connecting remote sites over the internet?

• A. LAN
• B. WAN
• C. VPN
• D. PAN

Answer: (C)

A Virtual Private Network creates a secure, encrypted tunnel over the public internet, linking remote sites so they operate as a single private network. It protects data in transit with encryption and authentication, so even though the data travels over untrusted networks, it remains confidential and intact. VPNs can connect whole networks at different locations (site-to-site) or allow individual users to access the network securely (remote-access). The other terms describe network types rather than a secure method for interconnecting sites over the internet: a LAN is a local network in one location, a WAN is a broad network that may span large areas but isn’t inherently secure, and a PAN covers short-range connections for personal devices.
