Which VPN securely connects two portions of a private network or two private networks?

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

Answer: (B)

Connecting two private networks securely over a public network is what a site-to-site VPN does. It uses VPN gateways at each site to establish an encrypted tunnel over the Internet, letting traffic flow between the networks as if they were one local network. This setup is ideal for linking branch offices, data centers, or partner networks without exposing the entire path to the public Internet.

SSL VPN, by contrast, is mainly for remote access from individual devices into a private network, often via a web portal or lightweight client, not for connecting two networks. Remote Access VPN serves a similar purpose for single devices, not for linking two private networks. An intranet is simply an internal network within an organization, not a VPN connection.
