QUESTION 20 OF 30

What is a VPN? Are there different types of VPNs?

This is a two-part question. During an interview, it is important that you listen to the entire question before you begin to answer. Missing part of a question, or failing to provide an accurate answer because you did not hear the question through might be the difference between getting the job and not getting the job. A good practice is to pause for two seconds after the interviewer has stopped speaking before you start to answer their question. Active listening will prevent you from the bad habit of waiting to speak.

"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 Cisco's mobile users and telecommuters. Intranet connects remote offices using a shared infrastructure, similar to a private network. Finally, extranet enables Cisco's suppliers, customers, and partners access to the company network using dedicated connections."
