Which technology allows a client computer to securely connect to a remote private network across the Internet?

• A. HTTP
• B. VPN
• C. FTP
• D. Telnet

Answer: (B)

A Virtual Private Network (VPN) is the technology that enables a client computer to securely connect to a remote private network over the Internet. VPNs create an encrypted tunnel between the client and the remote network, ensuring that data transmitted over the Internet remains private and secure from unauthorized access. This is especially important when accessing sensitive information or resources located on a private network, as it protects data from eavesdropping and interception. In contrast, HTTP (Hypertext Transfer Protocol) is not designed for secure communication and does not encapsulate the data in a secure manner. FTP (File Transfer Protocol) is also primarily for transferring files and lacks encryption, making it unsuitable for secure remote access. Telnet provides a command-line interface to communicate with remote devices, but like HTTP, it transmits data in plain text, exposing it to potential security risks. Thus, a VPN stands out as the most effective and secure method for connecting to remote private networks.
