You are the messaging engineer for your company. The company has 10,000 users worldwide. All users connect to their mailboxes by using Outlook Web Access. The company is transitioning from Microsoft Exchange Server 2003 to Exchange Server 2007. You plan to deploy five Client Access servers. You need to provide recommendations to improve the performance of Outlook Web Access. What should you do?

You are the messaging engineer for your company.

You plan to deploy Exchange Server 2007.

You need to recommend the number of Exchange Server 2007 servers required to meet the following requirements:

Support for Exchange ActiveSync.
If a server fails on any Exchange server, continue to provide message delivery and access to mailboxes.
Minimize the number of Exchange Server 2007 servers installed on your network.

How many Exchange Server 2007 servers should you recommend?

You are the messaging engineer for your company. Your company has a main office and a branch office. The main office has 1,500 users. The branch office has 300 users.

Your network contains a single Active Directory domain. An Active Directory site exists for each office.
The companys only connection to the Internet is from the main offices perimeter network.

You need to recommend the Exchange Server 2007 server roles for each office to meet the following requirements:

Inspect inbound e-mail for viruses and spam in the perimeter network.
Ensure that users can send and receive e-mail even if a single mailbox server fails.
Ensure that all message delivery services and Exchange Web Services are available even if a single server fails.
Minimize the number of Exchange Server 2007 servers.

Which server roles should you recommend? (Each correct answer presents part of the solution. Choose three.)

You are the messaging engineer for your company. Your messaging system is Exchange Server 2007. Your company is running a message archival system that removes messages that are older than 180 days. Due to compliance requirements, you need to allow users to retain e-mail in a folder in their mailboxes for up to 5 years. The folder must be automatically created by your Exchange Server 2007 servers. What should you recommend?

You are the messaging engineer for your company.

You have deployed Exchange Server 2007. The Mailbox server role has been deployed on a server named Server1.

The network is connected to the Internet through a single firewall. All outbound ports are open. Your firewall is configured to allow only inbound TCP port 443 to Server1.

You need to recommend changes to the Exchange Server 2007 organization to meet the following requirements:

Provide local and remote access to user mailboxes from Microsoft Office Outlook 2007.
Provide content, sender, and SenderID filtering on all inbound messages received from the Internet.

What changes should you recommend?

You are the messaging engineer for your company. Your company has a main office and one branch office. Each office is configured as an Active Directory site. The main office provides Internet access to the branch office. The branch office has 300 users.

You need to plan the Exchange Server 2007 deployment for the branch office to meet the following requirements:

Provide users with access to Outlook Web Access.
Provide a redundant solution for mailbox data in the event of a single server failure.
Support Microsoft Office Outlook 2007 and Microsoft Office Outlook 2003 clients.

What should you recommend?

You are the messaging engineer for your company. Your company has offices in New York, Montreal, and Vancouver.

Your company has an Exchange Server 2007 messaging system. The network consists of a single Active Directory forest. An Active Directory site exists for each office. Each site contains at least one domain controller.

The relevant portion of the network is configured as shown in the following diagram. Also shown in the diagram are the costs for the Active Directory site link.
You notice that all e-mails routed between New York and Vancouver are sent through the WAN link between New York and Vancouver.

You need to design a routing topology to deliver all e-mail messages between New York and Vancouver through the Montreal office. Your solution must maintain the existing Active Directory replication paths.

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

You are the messaging engineer for your company. The company has a main office and four branch offices. You are currently running Exchange Server 2007. Each office contains two clustered Mailbox servers, one Hub Transport server and one Client Access server.

Reduce disk I/O for the disks that contain the Exchange databases.
Increase the number of transactions that can be stored in memory.
Improve recoverability of data if the database becomes corrupt.

Which three configurations should you recommend? (Each correct answer presents part of the solution.
