Which of the following functions is performed by a virtual
private network (VPN)?
A. Hiding information from sniffers on the net
B. Enforcing security policies
C. Detecting misuse or mistakes
D. Regulating access
Answer / guest
Answer: A
A VPN hides information from sniffers on the net. Using
encryption, a VPN hides information. It works based on
tunneling. A VPN does not analyze information packets and
therefore cannot enforce security policies, nor does it
check the content of packets and so cannot detect misuse or
mistakes, and it does not perform an authentication
function, and hence cannot regulate access.
