Your Active Directory forest consists of the domain controllers shown in the table.
Site1 and Site2 are connected by an unreliable WAN link.
You have two Exchange Server 2003 servers at each site. You plan to remove Server3 from the network.
You need to ensure that messaging services at both sites are available if the WAN link fails, after Server3 is removed from the network. The solution must minimize replication traffic between the sites.
What should you do first?

You are the Exchange administrator for you company. The relevant portion of the network is configured in the follow Diagram.
The network serves two offices, one in London and one in Paris. Each office contains a single Exchange Server 2003 computer in its own routing group.
The routing groups are connected by a routing group connector.
The only network traffic between the two offices is e-mail messages. There is a permanent WAN link that connects the two offices. The WAN link is connected to a hardware router in each office.
The two hardware routers each also have an ISDN dial-up interface. Demand-dial routing is defined between the two offices.
You view network utilization statistics in the Paris office, and you discover that traffic from the Paris Exchange server frequently causes the ISDN link to connect.
There is little utilization of the permanent WAN link between the two offices. The WAN link has been very reliable and has suffered no downtime.
You need to ensure that the ISDN link is used only when the permanent WAN link fails.
What should you do in the Paris office?

You are the Exchange administrator for your company. The Exchange organization contains a single Exchange Server 2003 computer.
The exchange server contains one storage group that has three mailbox stores. Each mailbox store contains: 200 mailboxes.
The company’s service level agreement (SLA) requires that Exchange must not be offline for more than four hours. The SLA requires that in the event of data corruption, the most current data must be restored.
You want to test the recovery process on the existing Exchange server after business hours. You need to ensure that the mailbox stores can be restored within four hours without losing the current production data.
What should you do before performing the test restore operation?

You are the Exchange administrator for your company. The Tokyo office has six servers that run Exchange Server 2003. The Osaka office has four servers that run Exchange Server 2003. The servers are all in a single routing group.
The WAN administrator reports a large amount of e-mail traffic on the network connection between the Tokyo and Osaka offices.
The traffic is interfering with critical line-of-business database applications that must run during business hours.
The database servers are in the Tokyo office, but many of the users are in the Osaka office.
The large amount of WAN traffic is caused by e-maiI messages that have large attachments.
You need to ensure that large e-mail messages are delivered between offices only after business hours.
What should you do?

You are the Exchange administrator for your company. Exchange Server 2003 runs on two Microsoft Windows Server 2003 member servers.
The company�s network consists of a single Active Directory domain.
Two domain controllers are located in a single Active Directory site. Inbound SMTP mail from the Internet arrives on both Exchange servers.
You configure sender filtering to reduce the amount of junk e-mail that is received by company users.
You specify a list of known junk e-mail senders in the blocked-sender list, users report that they still receive e-mail from these senders.
You need to ensure that users do not receive messages from the blocked-sender list.
What should you do on both Exchange servers� SMTP virtual servers?
