What term describes a private network that enables encrypted communications over the Internet between two computers?

• A. Private Cloud Network
• B. Intranet
• C. Virtual Private Network
• D. Local Area Network

Answer: (C)

Encrypted communication over the public Internet to connect two machines is achieved by a Virtual Private Network. A VPN creates an encrypted tunnel over the Internet, so data between the two endpoints stays confidential and intact, making them appear as though they’re on a private network even though they’re communicating over public infrastructure. This setup supports secure remote access and site-to-site connections, using encryption and authentication to protect the traffic. The other terms don’t fit as precisely. A private cloud network refers to dedicated cloud resources for an organization rather than a point-to-point encrypted link between two devices. An intranet is a private internal network for an organization and doesn’t inherently describe secure Internet-based communication between two computers. A local area network is a small, local network typically confined to a limited area and not about secure communication over the Internet.
