Front 8

A virtual connection between a client and a remote network, two remote networks, or two remote hosts over the internet is known as what?

Back 8

VPN (Virtual Private Network)

Front 9

This type of server runs communications services that enable remote user's to log on to a network and grant privileges to the network's resources.

Back 9

RAS (Remote Access Server)

Front 10

The two types of remote access servers are:
