Which VPN type enables remote users to access a private network over the Internet?

• A. SSL VPN
• B. Site-to-site VPN
• C. Remote Access VPN
• D. Intranet

Answer: (A)

Remote access to a private network over the Internet is provided by a VPN that lets individual users connect from remote locations. An SSL VPN uses the SSL/TLS protocol to secure that connection, often through a web portal or a lightweight client. Because SSL runs over standard HTTPS, it usually traverses firewalls and proxies easily and gives encrypted access to internal resources as if the user were locally connected. A site-to-site VPN, by contrast, links entire networks at different sites rather than individual remote users. An intranet is the private network itself, not a VPN mechanism. So SSL VPN is a practical, user-friendly way to enable remote users to reach a private network over the Internet.
