Which statement best describes VPN usage as described?

• A. VPN is used to connect printers over a LAN.
• B. VPN stands for Virtual Public Network.
• C. VPN provides private communications over a public network for confidential data, often used by mobile users.
• D. VPN replaces a firewall entirely.

Answer: (C)

VPN usage centers on providing private communications over a public network for confidential data, often used by mobile users. It works by creating an encrypted tunnel between the user's device and the target network, so information remains confidential and protected from eavesdropping as it travels over the internet. This makes it ideal for remote or on-the-go workers who need secure access to company resources from anywhere. The idea isn’t about printing over a LAN, and the acronym stands for Virtual Private Network, not Virtual Public Network. A VPN also doesn’t replace a firewall entirely; firewalls monitor and block or allow traffic based on rules, while a VPN secures the path itself—often both are used together to build a secure, accessible network.
