Which technology provides encrypted tunnel for internet traffic to protect privacy?

• A. HTTPS
• B. Data in transit
• C. VPN
• D. Email encryption

Answer: (C)

An encrypted tunnel for all internet traffic is created by a VPN. A VPN routes your device’s data through a secure, encrypted channel to a VPN server, so anyone on the local network (like on public Wi‑Fi) can’t read or tamper with your traffic. It also masks your real IP by making your traffic appear to come from the VPN server, adding a layer of privacy. This differs from HTTPS, which only protects the connection to a specific site and doesn’t hide all your traffic or destinations beyond that site. “Data in transit” is a general concept of encryption while data is moving, not a specific technology that builds a tunnel. Email encryption protects content of messages, not all internet traffic across every app. So the technology that provides the encrypted tunnel for internet traffic is a VPN.
