VPNs are implemented to provide:
A . A secure connection within a private network.
B . A secure connection through public networks.
C . Additional encryption by using IPSec.
D . Additional security for selected computers.
Answer: B
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.
