Which type of network provides an encrypted means of transporting private data through the Internet?

• A. Wide area network (WAN).
• B. Local area network (LAN).
• C. Metropolitan area network (MAN).
• D. Virtual private network (VPN).

Answer: (D)

A Virtual Private Network (VPN) is specifically designed to create a secure and encrypted connection over the Internet. By using protocols that ensure data security, a VPN establishes a private tunnel for data transmission, safeguarding user information from potential eavesdroppers, hackers, and other unauthorized access. This encryption is crucial for transporting private data, enabling secure communication, particularly in scenarios where sensitive information is involved, such as financial transactions or personal communications. A VPN effectively masks the user's IP address, adds a layer of anonymity, and ensures that even if data packets are intercepted, they cannot be deciphered without the proper encryption keys. Other types of networks like Wide Area Networks (WAN), Local Area Networks (LAN), and Metropolitan Area Networks (MAN) primarily focus on the geographical and technical aspects of data transportation but do not inherently provide the same level of security and encryption that a VPN does. A WAN connects multiple LANs over large distances, a LAN connects devices within a localized area, and a MAN spans a city. However, none of these networks inherently encrypt data as it travels across the Internet like a VPN.
