You are a messaging professional. Your company deploys a single Microsoft Exchange Server 2007 computer that has the following roles installed:
Mailbox server Hub Transport server Client Access Server
The Exchange organization has five Exchange Server 2003 routing groups.
Each routing group has a single direction routing group connector from the Exchange Server 2007 routing group to the respective Exchange Server 2003 routing group.
You instruct the Exchange administrators to create connectors from each Exchange Server 2003 routing group to the Exchange Server 2007 routing group during a scheduled change window. The firewall located at each location allows Exchange SMTP traffic between all the Exchange bridgehead servers at each location.
The Exchange administrators create routing group connectors by using the Exchange System Manager in Exchange Server 2003 during the scheduled change window.
In sites where the routing group connector was manually created, the e-mail messages sent from the Exchange Server 2003 computers are not delivered to the Exchange Server 2007 computers. All Exchange Server 2007 users can send e-mail messages to all other Exchange users.
You need to ensure that the messages from the Exchange Server 2003 computers are delivered to the Exchange Server 2007 computers.
What should you do to ensure that the messages from the Exchange Server 2003 computers are delivered to the Exchange Server 2007 computers.?
A.
Add the Exchange Server 2003 bridgehead computer to the ExchangeLegacyInterop universal security group.
B.
Create a SMTP connector from the Exchange Server 2003 bridgehead in Routing Group 1 to an Exchange
Server 2007 computer.
C.
Request that the firewall allow RPC access between the bridgehead in Routing Group 1 and the Exchange
Server 2007 bridgehead in the firewall.
D.
Enable LinkState updates on the bridgehead in Routing Group 1.
