Which statement about VPNs is true?

• A. They encrypt all data transmitted
• B. They only hide IP addresses
• C. They replace proxy servers
• D. They generate code documentation

Answer: (A)

VPNs create a secure, encrypted tunnel between your device and a VPN server. Through that tunnel, all the data your device sends is encrypted in transit, so anyone listening on the network can’t read it or tamper with it. That’s why the statement about encrypting all data transmitted is true in typical VPN use: encryption is a fundamental part of how VPNs protect your traffic. The other ideas don’t capture this core function: VPNs do more than hide your IP, they route your traffic through the VPN server, and they aren’t about replacing proxy servers or generating code documentation.
