Computer help

Question

Your boss wants you to configure his laptop so that he can access the company network when he is on the road. You suggest a VPN connection to him. He is very concerned about security and asks you how secure VPN is. What do you tell him?
A. Only mouse clicks and keyboard commands are transferred over the connection.
B. All traffic that flows between the laptop and VPN server is encrypted.
C. All of the tasks your boss will do will be on the desktop of the remote computer.
D. VPN integrates with NTFS so that only secure files are opened and modified.

Answer 1

A Virtual Private Network (VPN) is a "tunnel" connection between computers that performs just like a regular point-to-point network connection (that is, IP address to IP address).  It has the added feature that encryption is enabled so that no intermediate server (or computer or line monitor, etc.) can decode the information that is in the data portion of the packets.

 

Answers A, C, and D are simply not true.  This makes the choice pretty easy.  For (A), the VPN connections transfers all data just like a regular connection would; for (C) if your boss only needs his remote computer, why is he connecting to the company network?; and for (D) NTFS is the file system used by Windows PCs, but VPNs may connect UNIX/Linux machines, Apples, and even embedded computers (like inside a home security system or an automobile engine).
