Which statement best describes the difference between RAS and VPN servers?

• A. RAS provides encryption, VPN does not.
• B. RAS is a local area connection; VPN spans a large area.
• C. VPN requires telephone lines; RAS uses the internet.
• D. RAS is cloud-based; VPN is on-premises.

Answer: (B)

Understanding reach and transport method clarifies how these remote access technologies work. RAS (Remote Access Service) was designed to dial into a private network over telephone lines or dedicated links, which typically brings a user to a specific network site and has a more local or limited reach. A VPN (Virtual Private Network) uses the public Internet to create a secure tunnel to a private network, allowing access from anywhere in the world. So the defining difference is scope: RAS for local/limited access, VPN for wide-area coverage. While VPNs usually provide encryption, RAS can be configured with or without encryption, so the encryption feature isn’t the distinguishing factor. The other statements misstate the medium or scope—for example, VPN doesn’t inherently require telephone lines, and RAS isn’t inherently cloud-based or strictly on-premises.
