Correct Answer: ADE
Explanation/Reference:
IPSec can be run in either tunnel mode or transport mode. Each of these modes has its own particular uses and care should be taken to ensure that the correct one is selected for the solution:
Tunnel mode is most commonly used between gateways, or at an end-station to a gateway, the gateway acting as a proxy for the hosts behind it.
Transport mode is used between end-stations or between an end-station and a gateway, if the gateway is being treated as a host””for example, an encrypted Telnet session from a workstation to a router, in which the router is the actual destination.
