What is NOT a function of a virtual private network (VPN)?

• A. Secure connections over the public Internet
• B. Making calls over the Internet
• C. Accessing network resources remotely
• D. Creating a private "tunnel" for data

Answer: (B)

A virtual private network (VPN) is primarily designed to create secure connections over public networks, allowing users to access network resources remotely while protecting their data through encryption. One of its fundamental functions is to establish a private "tunnel" that ensures the integrity and confidentiality of the transmitted data. This is crucial for maintaining security when accessing sensitive information over unsecured networks. While VPNs can facilitate secure access to the internet, they do not inherently provide functionality for making calls over the Internet, such as VoIP services. These calls rely on separate technologies and protocols that may or may not utilize a VPN. Therefore, making calls over the Internet is not a direct function of a VPN, making this option distinct from the core capabilities of VPN technology.
