You are a messaging professional. Your companys messaging system consists of Microsoft Exchange 2000 Server computers and Microsoft Exchange Server 2003 computers. The company has a main office and 14 branch offices.
Each branch office is connected to the main office by a WAN link. A routing group is configured for each office. Each branch office routing group is connected to the main office routing group by a Routing Group Connector.
The company has started upgrading its messaging system to Microsoft Exchange Server 2007. All messaging servers will be replaced with new Exchange Server 2007 computers over a period of 18 months.
In the main office, one Exchange Server 2003 computer acts as a routing group bridgehead server. All other messaging servers in the main office are upgraded to Exchange Server 2007.
You install a new Exchange Server 2007 computer in a branch office. You implement the Mailbox server role, the Client Access Server role, and the Hub Transport server role on the new Exchange Server 2007 computer. You then move half of the user mailboxes in that office to the new computer.
The network administrators report that the SMTP traffic on the WAN has increased to an unacceptable level. Only the link between the main office and the branch office that has the new Exchange Server 2007 computer is affected.
You need to minimize the amount of Exchange-related SMTP traffic on the WAN during the upgrade.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A.
Disable the link-state routing table updates on the Exchange 2000 Server computers and the Exchange
Server 2003 computers.
B.
Designate the branch office Exchange Server 2007 computer as the bridgehead server for a new routing
group connection.
C.
Move all the Exchange 2000 Server computers and the Exchange Server 2003 computers into the
well-known Exchange Server 2007 DWBGZMFD01QNBJR routing group.
D.
Install a new Exchange Server 2007 computer as an Edge Transport server and configure an SMTP Send
Connector to use the branch office routing group bridgehead server as a smart host.
