You are a messaging professional. Your company uses a Microsoft Exchange
Server 2007 messaging system. The company has eight Microsoft Active Directory sites in two regions,
East and West.

You plan to implement a new e-mail application on your Exchange Server 2007 Hub Transport servers in
each site. The new application queries a database on a remote Microsoft Windows Server 2003 server by
using Lightweight Directory Access Protocol (LDAP).

The company security policy has the following requirements on the usage of Public Key Infrastructure
(PKI):

PKI-based encryption must be used for all application data transmissions in the West region.
PKI-based encryption must not be used in the East region due to conflicts with mission critical
applications.

You need to ensure that maximum confidentiality is provided to all data that is transmitted by the
application.

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. The messaging system consists of four Exchange Server 2007 servers as shown in the following table.

Server nameServer role installed
Server1Hub Transport
Server2Client Access
Server3Mailbox
Server4Mailbox

Each Mailbox server hosts 2,000 user mailboxes.

The motherboard on one of the Mailbox servers has failed. Users report that they cannot access their
mailboxes.

You need to ensure that the messaging system is fault tolerant. You also need to ensure that users have
access to their e-mail messages even if a single server fails.

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 2007 messaging system.

Your company has five offices located in five different regions.

Users use Microsoft Office Outlook 2007 and Microsoft Outlook Web Access (OWA) to access their
mailbox.

Exchange Server 2007 computers are deployed in each office. Each office contains an Exchange Server
2007 computer that runs the Hub Transport server role and the Client Access Server role. In addition,
there is an Exchange Server 2007 computer in each office that runs the Mailbox server role.

All Mailbox servers are configured to use Local Continuous Replication (LCR).

In the event of a single server failure, the company has the following new requirements:

Users must be able to access their mailboxes by using Office Outlook 2007 or OWA.
The flow of e-mail messages must be undisrupted.

You need to meet the outlined requirements. You want to achieve this goal by deploying as few servers as
possible.

What should you do?

You are a messaging professional.

Your company uses a Microsoft Exchange Server 2007 messaging system. You implement custom
message classifications for your company.

Your company provides financial audits to customers as part of its accounting services. Users require the
ability to classify messages pertaining to financial audits that are sent to the customers.

You deploy a message classification that uses the default classification list.

You need to ensure that all the users can use the custom classification each time they send an e-mail
message pertaining to financial audits.

What should you do?

You are a messaging professional. Your company uses a Microsoft Exchange
Server 2007 messaging system. The company has a vendor named Contoso, Ltd.

The company has the following message size policy requirements:

Messages sent to Contoso must not exceed 30 MB in size.
Other messages sent to the Internet must not exceed 5 MB in size.

You need to meet the outlined requirements without affecting any other messaging functions.
