What is a VPN? Are there different types of VPNs?
This is a two-part question. During an interview, it is vitally important that you listen to the entire question before answering. Since the first part of this question is relatively easy, you may begin to answer it before the interviewer has finished asking it. Failing to answer the question because you missed part of the question could be the misstep that decides the interview. A good practice is to pause for two seconds after the interviewer has stopped speaking before you start to answer their question.
"VPN stands for Virtual Private Network, and establishes a network which can be accessed remotely, but only by authorized users. VPNs are more secure and less expensive when compared to wide-area or WAN networks. VPNs enable secure transactions and confidential data to be transferred between multiple locations and keep proprietary information secure against potential intrusions. There are three types of VPNs, including Access, Intranet, and Extranet, the differences being the way users connect to the company's network using VPN. Access provides connectivity to mobile users and telecommuters. Intranet connects remote offices using a shared infrastructure, similar to a private network. Finally, extranet enables suppliers, customers, and partners access to the company network using dedicated connections."
