What is the primary function of a VPN?

• A. To speed up internet connection
• B. To create a secure connection over the internet
• C. To monitor network traffic
• D. To store data remotely

Answer: (B)

The primary function of a VPN, or Virtual Private Network, is to create a secure connection over the internet. VPNs achieve this by encrypting the user's internet traffic and routing it through a secure server, which helps protect sensitive data from being intercepted by hackers or unauthorized entities. This secure tunnel not only safeguards private information but also allows users to access resources on the internet as if they were connected to a local network, improving privacy and security.

By establishing a secure connection, VPNs are particularly beneficial for users who are accessing the internet over unsecured networks, such as public Wi-Fi, where data is more vulnerable to interception. In contrast, while other choices might touch on aspects of internet connectivity or security, they do not encapsulate the core purpose of a VPN, which is primarily focused on ensuring a secure communication channel.
