Multiple answer, multiple-choice

You are the messaging engineer for your organization and plan to deploy Exchange Server 2007 server in your organization, limiting the number of servers to as few as possible. Which Exchange Server roles should you deploy to protect your Exchange environment from unwanted message traffic such as spam and intelligently route messages within an Exchange 2007 environment? (Choose two.)

A.    Client Access Server.
B.    Edge Transport Server.
C.    Hub Transport Server.
D.    Unified Messaging.

Answer:
B. Edge Transport Server.
C. Hub Transport Server.

Tutorial:
To protect your Exchange environment from unwanted message traffic and intelligently route messages within an Exchange 2007 environment, you should deploy Edge Transport Server and Hub Transport Server roles.

The Edge Transport Server role protects your Exchange environment from unwanted message traffic such as anti-virus and spam and is deployed outside the Active Directory forest in the perimeter network. Edge Transport Server allows you to inspect inbound e-mails in the perimeter network for spam and viruses. You should ensure that anti-spam components in Exchange Server 2007 are up-to-date.

Besides using Windows Update, you can use Microsoft Exchange 2007 Standard Anti-spam Filter Updates and Microsoft Forefront Security for exchange servers. Microsoft Exchange 2007 Standard Anti-spam Filter updates every two weeks. Microsoft Forefront Security for Exchange Server Filter updates every 24 hours.

The Hub Transport Server role helps you intelligently route messages within an Exchange 2007 environment. The Hub Transport Server routes a message destined to multiple recipients by identifying the most efficient route to send the message. The Hub Transport Server keeps the messages intact for multiple recipients until the most appropriate endpoint by transmitting only one copy of the message to the server. At the server, the message is broken apart, with a copy of the message dropped into each of the recipient's mailboxes at the end point.

The Hub Transport role, Client Access role and Mailbox Server roles of Exchange Server 2007 can be installed on a single server. The Edge Transport Server role cannot be installed on a server that holds other roles; therefore the Edge Transport Server needs to be installed on a separate server. If you need to deploy an Edge Transport Server with another Exchange Server 2007 server to implement the various server roles, you should use two different Exchange 2007 servers.

Deploying the Client Access Server role will not help you achieve the objective. This role in Exchange Server 2007 is required to communicate between themselves and Mailbox Servers. The Client Access Server role controls access to mailboxes from all clients that are not using Microsoft Outlook and do not use Messaging Application Programming Interface (MAPI) connections by using Outlook Web Access (OWA), Exchange ActiveSync, Outlook Anywhere, Post Office Protocol 3 (POP3) or Internet Message Access Protocol (IMAP4).

Deploying the Unified Messaging role will not help you achieve the objective. The Unified Messaging role allows integrating fax, voice mail and e-mail into a user's mailbox. It is recommended that the Unified Messaging role be installed only when the infrastructure to support this role already exists. The Unified Messaging role requires integration with a third-party Private Branch Exchange (PBX) system.

Objective: Design and plan coexistence and migration.
Sub-objective: Design and plan for migration of legacy Exchange features.

Single answer, multiple-choice

You are the messaging engineer for TXGlobal Corp. Your organization has two Active Directory forests: TXGlobalForestA and TXGlobalForestB. There is a cross-forest trust relationship between these forests. Both the forests have an Exchange Server 2003 messaging system. You plan to migrate the messaging system in TXGlobalForestB to Exchange Server 2007 in six months. You also plan to migrate all computers from Microsoft Office 2003 to Microsoft Office 2007 in the same time frame.

You need to recommend a solution to ensure users in one forest are able to access free/busy data about users in both forests for the next six months. What should you recommend?

A.    Use the global address list (GAL) Synchronization feature in Microsoft Integration Identity Server (MIIS) 2003.
B.    Use the Availability service.
C.    Use the /EnableLegacyOutlook parameter while installing the Mailbox Server.
D.    Use the Microsoft Exchange Server Inter-Organization Replication tool.

Answer:
D. Use the Microsoft Exchange Server Inter-Organization Replication tool.

Tutorial:
You should use the Microsoft Exchange Server Inter-Organization Replication tool to ensure users in one forest are able to access free/busy data about users in both forests. The Microsoft Exchange Server Inter-Organization Replication tool allows sharing of free/busy data between users in a cross-forest environment, where one forest does not have any Exchange 2007 Mailbox servers, or users do not use Outlook 2007 to access their e-mail. In this scenario, neither forest will have Exchange Server 2007 for the next six months. To use the Inter-Organization Replication tool, you must have at least one Exchange 2000 Server or Exchange Server 2003 server in each forest.

You should not use the GAL Synchronization feature in MIIS 2003 to ensure users in one forest are able to access free/busy data about users in both forests. GAL Synchronization feature provides users in a forest access to global address list information of both forests. The GAL Synchronization feature does not provide access to free/busy data. The mail recipient information is stored in a GAL for a single forest.

You should enable and configure the GAL Synchronization feature in MIIS 2003 if you have a cross-forest environment. This will ensure the GAL in both forests contains mail recipient information for both forests.

You should not use the Availability service to ensure users in one forest are able to access free/busy data about users in both forests. You should install Exchange Server 2007 in both forests to use the Availability service to enable users in a cross-forest environment to gather free/busy data about users in both forests.

Also, to use the Availability service, users should use Microsoft Office Outlook 2007 client to access their e-mail messages. In this scenario, Exchange Server 2007 will not be deployed for six months. You should use the Microsoft Exchange Server Inter-Organization Replication tool to ensure users in one forest are able to access free/busy data about users in both forests.

You should not use the /EnableLegacyOutlook parameter while installing the Mailbox Server to ensure users in one forest are able to access free/busy data about users in both forests. This parameter is used to create a public folder database on a Mailbox server. To use this parameter, client computers in your messaging system must use Microsoft Office Outlook 2003 or earlier versions. For example, if you want to remove the need for public folder databases in a forest, then you should ensure all client computers in that forest are running Microsoft Office Outlook 2007.
