Your network is going to implement a new network security solution, and as part of this you are configuring IPSec on a Windows Server 2003 machine. Which of the following is the description of the Client (Respond Only) default IPSec Policy?

A.
This policy is used for normal communications, and any system with this policy enabled will have the ability to communicate using IPSec if required, or requested.

B.
This policy is used when all IP network traffic is to be secured. Any system with this policy enabled will always enforce secure communications using IPSec.

C.
This policy is used when IP traffic is to be secured, and to allow unsecured communication with clients that do not respond to the request.

D.
This policy is used when clients are the only machines on the network that need IP traffic to be secured.
Any client with this policy enabled will initialize secure communications with other clients running this policy.

E.
This policy is used when clients must respond to IPSec servers. If the client does not use IPSec, network communications will fail.
