    What is the 'Virtual Private Network'?

    A)  It is a private computer network of an organisation where the remote users can transmit encrypted information through the server provider

    B)  It is a computer network across a public internet that provide users access to their organisation's network while maintaining the security of the information transmitted

    C)  It is a computer network in which users can access a shared pool of computing resource through a service provider

    D)  None of the above

    Correct Answer: B

    Solution :

    [b] A virtual private network (VPN) is a technology that creates an encrypted connection over a less secure network. The benefit of using a VPN is that it ensures the appropriate level of security to the connected systems when the underlying network infrastructure alone cannot provide it. The justification for using a VPN instead of a private network usually boils down to cost and feasibility: It is either not feasible to have a private network (e.g., for a traveling sales rep) or it is too costly to do so. The most common types of VPNs are remote-access VPNs and site- to-site VPNs.
