You are a messaging professional. Your company is upgrading a Microsoft
Exchange Server 2003 messaging system to a Microsoft Exchange Server 2007 messaging system.

Four Exchange Server 2007 Mailbox servers host all user mailboxes. Two Hub Transport servers and one
Client Access Server have been deployed.

Two computers that run Exchange Server 2003 host public folders. Replicas of all public folders exist on
both public folder servers.

Users access their mailboxes by using Microsoft Office Outlook 2007 and Microsoft Outlook Web Access
(OWA).

The company has the following requirements:

A single-server failure must disrupt OWA services for the fewest number of users.
A single-server failure must disrupt access to free/busy information for the fewest number of users.

You need to implement a high availability solution that meets the requirements.

What should you do?

You are a messaging professional. Your company uses a Microsoft Exchange
Server 2007 messaging system.

The company has two Microsoft Active Directory forests. You configure a forest trust between the two
forests. Each forest has an Exchange Server 2007 organization. All client computers run Microsoft Office
Outlook 2007.

You need to ensure that users can obtain detailed cross-forest free/busy data of other users.

Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You are a messaging professional. Your company uses a Novell GroupWise
messaging system.

Your company has Microsoft Exchange Server 2003 computers and Microsoft Exchange Server 2007
computers in a single Exchange organization. You plan to migrate the mailboxes from the Novell
GroupWise server to the Exchange Server 2007 computers. The company schedules the migration to be
completed in two months. During the migration, users in one messaging system must be able to exchange
e-mail messages with users in the other messaging system. They must be able to select users from the
Global Address List to send messages. No additional functionality must be enabled.

You need to meet the outlined requirements.

What are two possible ways to achieve this goal? (Each correct answer presents a complete solution.
Choose two.)

You are a messaging professional. Your company uses a Microsoft Exchange
Server 2003 messaging system. Your company deploys Microsoft Exchange Server 2007 Mailbox servers
and Exchange Server 2007 Hub Transport servers within the existing messaging system. One Client
Access Server is also deployed. Client computers run Microsoft Office Outlook 2003.

You move 50 user mailboxes to a new Exchange Server 2007 Mailbox server. These 50 users report that
access to public folder information and free/busy information for other users is very slow.

You need to ensure that all users continue to have access to public folders and can see the free/busy times
for other users after their mailboxes are moved to an Exchange Server 2007 Mailbox server.

What should you do?

You are a messaging professional. Your company uses a Microsoft Exchange
Server 2003 messaging system and a single Microsoft Active Directory domain that has three sites named
Site1, Site2, and Site3.

The default site link configuration has not been modified. The WAN connections are as shown in the
following exhibit. (Refer to the Exhibit.)

The company plans to deploy Microsoft Exchange Server 2007 computers in the existing Exchange
Server 2003 messaging system.

You need to ensure that the fastest link is used to route all e-mail messages without affecting the Active
Directory replication.

What should you do?

You are a messaging professional. Your company has a Microsoft Exchange
2000 Server organization. The companys corporate network consists of a main office and two branch
offices, Branch Office 1 and Branch Office 2. The company uses a Microsoft Windows 2000 native-mode
Active Directory forest.

The infrastructure setup at each office includes an Active Directory site, Exchange 2000 Server
computers, and domain controllers.

The domain controllers at the main office and Branch Office 1 run Windows 2000 Advanced Server
Service Pack 2 and are also global catalog servers.

The domain controllers at Branch Office 2 run Windows 2000 Advanced Server Service Pack 2 but are
not global catalog servers.

The company plans to upgrade to a Microsoft Exchange Server 2007 organization. The company also
plans to install Exchange Server 2007 computers at all the offices.

You need to prepare the infrastructure for the deployment of Exchange Server 2007.

Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You are a messaging professional. Your company uses a Microsoft Exchange
Server 2007 messaging system.

Exchange Server 2007 computers do not contain public folder databases. All users run Microsoft Office
Outlook 2007 as their messaging client.

The company acquires a new company. The acquired company uses a Microsoft Exchange Server 2003
messaging system. The users in the acquired company run Microsoft Office Outlook 2003 as their
messaging client. Your company plans migration of the mailboxes from the Exchange Server 2003
messaging system to the Exchange Server 2007 messaging system.

You need to ensure that all the users from the acquired company can view the calendar availability
information of users in your companys Exchange Server 2007 messaging system when their mailboxes
are migrated to Exchange Server 2007.

What should you do?

You are a messaging professional. Your company, A. Datum Corporation,
uses a Microsoft Exchange Server 2007 messaging system. A. Datum deploys an Edge Transport server
and enables edge synchronization.

A. Datum acquires a new company named Contoso, Ltd. Contoso uses a Microsoft Exchange Server 5.5
messaging system. The external SMTP domain names for the two companies are adatum.com and
contoso.com respectively.

A WAN connection is installed between A. Datum and Contoso. This WAN connection is used to send
and receive e-mail messages. The e-mail messages sent to each company on the Internet are delivered
directly to the SMTP server of the respective company.

Your company decommissions the SMTP server that receives e-mail messages on the Internet at Contoso.
Your company plans to route e-mail messages for users at Contoso through the Internet connection at A.
Datum. You modify the MX record for contoso.com to refer to the host record of the Edge Transport
server that is used by A. Datum.

You need to ensure that each company continues to receive e-mail messages on the Internet.

What should you do?

You are a messaging professional. Your company has 60 Microsoft
Exchange Server 2003 computers in 27 offices. A Microsoft Active Directory site and an Exchange
Routing group are configured for each office.

Six of the offices are your companys regional headquarters. In your companys main office and each
regional headquarters, one or more Exchange Server 2003 computers are used as Microsoft Outlook Web
Access (OWA) front-end servers. Users connect to the OWA front-end servers in their own region to
access their mailboxes on the Internet.

Your company plans to upgrade all Exchange Server 2003 computers to Microsoft Exchange Server 2007
computers in the next 12 months. Your company wants to maintain all existing functionality during the
migration.

Your companys messaging administrators create the following upgrade plan:

First, upgrade the main office in the following order:

1. Install Exchange Server 2007 computers as Mailbox servers and Hub Transport servers.
2. Move all mailboxes to the Exchange Server 2007 computers.
3. Replace the OWA servers with Exchange Server 2007 Client Access Servers.

Next, upgrade the regional offices in the same order.

Finally, upgrade the remaining offices in the following order:

1. Install Exchange Server 2007 computers as Mailbox servers, Hub Transport servers, and Client Access
Servers.
2. Move all mailboxes to the Exchange Server 2007 computers.

You need to modify the plan to support the coexistence of Exchange Server 2003 computers and
Exchange Server 2007 computers during the migration. You also need to ensure that all the existing
messaging services are maintained.

What should you do?

You are a messaging professional. Your company plans to upgrade from a
Microsoft Exchange Server 2003 messaging system to a Microsoft Exchange Server 2007 messaging system.

The Microsoft Active Directory infrastructure is configured as a single forest. The forest includes a
dedicated root domain and child domains. Each domain has a separate messaging team.

The company plans to prepare the Active Directory domains for the Exchange Server 2007 messaging
system. The company has the following requirements:

The Active Directory domains must be prepared by the respective messaging teams.
The Active Directory team must perform an unattended preparation of the Active Directory Schema
from a centralized location.
The Active Directory domains must be configured with the least amount of administrative privileges
possible.

You need to create a deployment plan that meets the outlined requirements.
