What is a VPN and when would you use one?

• A. A VPN is a type of antivirus software.
• B. A VPN is a streaming service.
• C. A VPN automatically backs up files to the cloud.
• D. A VPN creates a secure encrypted tunnel for network traffic, protecting data on public networks or when accessing resources remotely.

Answer: (D)

A VPN creates a secure encrypted tunnel for your network traffic, protecting data on public networks or when accessing resources remotely. When you connect to a VPN, your data is wrapped in encryption and sent to a VPN server, so anyone snooping the local network can’t read it. It also can make your online activity appear to come from the VPN server’s location, which helps with remote access to resources and can enhance privacy. You’d use a VPN when you’re on public or untrusted networks, like a coffee shop or airport Wi‑Fi, or when you need to access company resources securely from home or while traveling. It’s also helpful for maintaining privacy on shared networks. It isn’t antivirus software, a streaming service, or a cloud backup solution.
