Final answer:
It is true that VPNs can be used to connect two or more LANs, allowing secure data transmission over a WAN as if the LANs were on the same network.
Step-by-step explanation:
The statement "Virtual private networks can be used to connect two or more LANs" is true. A Virtual Private Network (VPN) is a technology that creates a secure and encrypted connection over a less secure network, such as the internet. VPNs can connect multiple networks together, allowing for the secure transmission of data between these networks. For example, a company with offices in different locations may use a VPN to connect each office's local area network (LAN) to a single, secure wide area network (WAN), making it seem as though all LANs are on the same network and enabling secure interoffice communication.
