Concerning virtual private networks (VPN), which of the following is not true?
A) VPNs provide the functionality of a privately owned network using the Internet.
B) Using VPN software to encrypt information while it is in transit over the Internet in effect creates private communication channels, often referred to as tunnels, which are accessible only to those parties possessing the appropriate encryption and decryption keys.
C) The cost of the VPN software is much less than the cost of leasing or buying the infrastructure (telephone lines, satellite links, communications equipment, etc.) needed to create a privately owned secure communications network.
D) It is more expensive to reconfigure VPNs to include new sites than it is to add or remove the corresponding physical connections in a privately owned network.
