What is a primary feature of a VPN (Virtual Private Network)?

A primary feature of a Virtual Private Network (VPN) is providing a secure connection over a public internet connection. This means that a VPN creates a private tunnel through which data can travel securely, even while using an unsecured or public network. The VPN achieves this through encryption protocols, which protect the data being sent and received, ensuring that unauthorized users cannot easily access or intercept the communication.

This secure connection helps protect sensitive information, such as personal data and organizational communications, from potential threats that exist on public networks. By using a VPN, users can maintain privacy and security while accessing the internet or remote networks.

Other choices highlight characteristics that do not align with the purpose of a VPN. For instance, the idea of a direct line of sight connection refers to a physical and unobstructed connection, which is not relevant to how VPNs operate. Additionally, a network without encryption or one that allows public access contradicts the very principle of a VPN, which is designed to secure communications against eavesdropping and unauthorized access.
