You work in an international company which is named TXTWIN. And you’re in charge of the company network and use Microsoft BizTalk Server 2006 R2.
Now you’re developing a solution. You intend to use AS2 to deliver documents to a single trading partner. A solicit-response HTTP send port is configured to deliver documents to the trading partner and to receive the corresponding MDN acknowledgement. A BizTalk party is created to represent the trading partner. A public key certificate and a private key certificate are added to the Windows certificate store. What should you do to make sure that the AS2 documents can be transmitted successfully?

A.
In the Certificate properties of the HTTP send port, you should reference the public key.
In the Certificate properties of the BizTalk group, you reference the private key.

B.
In the Party as AS2 Message Receiver properties of the BizTalk party, you should reference the public key.
In the Certificate properties of the HTTP send port, you reference the private key.

C.
In the Party as AS2 Message Receiver properties of the BizTalk party, select the Sign Message check box.
In the Party as AS2 Message Sender properties of the BizTalk party, you should select the Sign MDN check box.

D.
You should paste the thumbprint of the private key in the AS2-To field in the Party as AS2 Message Receiver properties of the BizTalk party.
Paste the thumbprint of the public key in the AS2-From field in the Party as AS2 Message Receiver properties of the BizTalk party.
