Which statement best differentiates a VPN from a proxy?

• A. A VPN forwards requests on behalf of a client, typically for anonymity or caching; a proxy encrypts traffic end-to-end
• B. A VPN is always faster than a proxy
• C. A proxy provides encryption for all traffic, while a VPN does not
• D. A proxy forwards requests on behalf of a client, typically for anonymity or caching; a VPN creates an encrypted tunnel for all traffic between the device and the VPN endpoint

Answer: (D)

The key idea is how these tools handle traffic and security. A proxy sits in between applications and the destination, forwarding requests on behalf of the client and is often used for anonymity or caching for specific traffic. It doesn’t automatically encrypt all traffic from your device to the sites you visit. A VPN, on the other hand, creates an encrypted tunnel for all traffic between your device and the VPN server, so everything you send or receive is protected up to that endpoint and your real IP is hidden from the sites you reach. So the best way to differentiate is: a proxy forwards requests for anonymity or caching as a middleman for specific traffic, while a VPN establishes an encrypted tunnel for all traffic between the device and the VPN endpoint. The other statements mix up how VPNs and proxies work—for example, not all VPNs are faster than proxies, and proxies don’t inherently provide encryption for all traffic.
