What is the purpose of a VPN?

• A. Creates a secure encrypted tunnel for remote access to a network
• B. Speeds up internet by caching pages
• C. Provides antivirus protection
• D. Serves as default gateway

Answer: (A)

A VPN is designed to create a secure, encrypted tunnel over a public network so you can access a private network remotely. The encryption protects your data from being read or tampered with as it travels between your device and the VPN server, which is especially important on untrusted networks like public Wi‑Fi. This setup lets you connect to a company or home network securely, access internal resources, and appear as if you’re part of that network even while away.

It doesn’t speed up internet connections by caching pages, which is something a caching system or browser feature does. It also isn’t antivirus protection, which guards against malware. And while routing through a VPN is common, a VPN’s role isn’t to serve as the default gateway for all traffic by itself.
