A VPN is a/an:
A . Encrypted connection across the Internet.
B . Virtual network within your local area network (LAN).
C . Communication tunnel between VLANs.
D . Personal network for your use only.

Answer: A

Explanation:

VPN is a network that is constructed by using public wires ― usually the Internet ― to connect to a private network, such as a company’s internal network.

There are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
