Which technology is used to create secured connections to other networks over the Internet?

• A. Virtual Private Network (VPN)
• B. Virtual Memory Manager (VMM)
• C. VoIP
• D. Warm Site

Answer: (A)

A Virtual Private Network (VPN) is used to create secured connections to other networks over the Internet. It works by establishing an encrypted tunnel between your device or a network and the remote network, so all data passing through that path is protected from eavesdropping, tampering, and impersonation. This encryption, along with authentication, ensures confidentiality and integrity even though the underlying transport is an open, public network. VPNs support remote access for individuals and site-to-site links that connect entire networks as if they were directly connected.

The other options don’t fit the goal here. A Virtual Memory Manager handles how an operating system maps memory, not how networks are secured. VoIP is technology for transmitting voice over IP networks, not for creating secure connections. A Warm Site is a disaster recovery facility concept, not a method for securely linking networks over the Internet.
