Frankie wants to connect two remote sites so that they appear to be on the same local network segment. What type of solution is best suited to this requirement if she wants traffic sent between the locations to be secure despite traversing the public Internet?

VPNs, or virtual private networks, are commonly established between two locations to provide a secure connection that can make the networks appear to be on the same network segment. A VLAN may then be used if desired, but a VLAN alone does not provide encryption and cannot be set up across a public connection. TLS encapsulating each service would provide security, but that would not make the two sites appear to be on the same network segment. Reclassifying the data does not secure the data or make the networks appear to be on the same segment, either.
