Your network contains two Active Directory sites. The sites connect to each other by using a WAN link. 
You plan to deploy two Exchange Server 2010 Mailbox servers and two Client Access servers in eachsite. 
Each site will contain a Client Access array. 
You need to recommend a solution to deploy Hub Transport servers. The solution must meet the following requirements：
.Continue to deliver e-mail messages to users in other sites if a single Hub Transport server fails .Support the planned Client Access array deployment.Minimize the number of Exchange servers
What are two possible ways to achieve this goal？（）

Your network contains two Active Directory sites named Site1 and Site2. Only Site1 can be accessed from the Internet. You have an Exchange Server 2010 organization. 
You deploy a Client Access server in Site1 and enable Windows Integrated Authentication for OutlookWeb App （OWA）. 
In Site2， you deploy a Mailbox server and a Client Access server. 
You need to configure the Exchange organization to meet the following requirements：
.Allow users to access their mailboxes from the Internet by using OWA 
.Prevent authentication prompts from displaying when users connect to OWA by using domain- joinedcomputers that are connected to the internal network 
What should you do？（）

Your network consists of an Active Directory forest that contains two sites named Site1 and Site2. From the Internet， users can only access servers in Site1. You have an Exchange Server 2007 organization. 
Each site contains servers that run the Client Access server role， the Mailbox server role， and the HubTransport server role. 
You plan to transition the organization to Exchange Server 2010. 
You need to recommend the server role that you must transition first to Exchange Server 2010. Your solution must provide the least amount of downtime for users in the organization. 
Which servers should you transition first？（）

Your network contains an Active Directory forest. All domain controllers run Windows Server 2008. 
You have an Exchange organization that consists of the servers shown in the following table.You plan to implement moderated transport for distribution groups in the organization. 
You need to recommend changes to the organization to support the planned implementation. 
What should you recommend？（）

You have an Exchange Server 2003 organization. 
All users connect to their mailboxes by using Microsoft Office Outlook. 
You start to transition the organization to new Exchange Server 2010 servers. The new servers are on a secured subnet that is separated by a firewall. You will move half of the mailboxes to the new servers. 
Client Access servers and Mailbox servers are on the secured subnet. Client computers on the network can access the Client Access servers. 
You need to recommend a solution that allows users to connect to Public Folders by using Outlook orOutlook Web App （OWA）. 
What should you include in the solution？（）

Your company has two main offices named Main1 and Main2. An Active Directory site exists for each office. Users connect locally to servers in both offices. 
The offices connect to each other by using a high-speed WAN link. You plan to deploy Exchange Server 2010. 
You need to plan the deployment of Mailbox servers to meet the following requirements：
.Ensure that users can access their mailbox from a server in their site， if a single Mailbox server fails .Ensure that users can access their mailboxes remotely if a site fails .Minimize the number of servers
How many Mailbox servers should you include in the plan？（）

Your network contains two data centers named Datacenter1 and Datacenter2. An Active Directory site exists for each data center. 
The data centers connect to the Internet by using a direct link. 
The data centers connect to each other by using a high-speed WAN link. 
You plan to deploy Exchange Server 2010 Mailbox servers in both data centers. You need to plan message routing to meet the following requirements：.Ensure outbound delivery of e-mail messages if a single server fails .Automatically load balance the Hub Transport server in each site .Deploy the minimum number of servers
What should you include in the plan？（）

You have an Exchange Server 2010 organization that consists of 50 Exchange Server 2010 servers. Your companys security policy states that approved Exchange and Windows Server patches and securityupdates must be applied to all Exchange servers within one week of being released. 
You need to recommend a patch management solution that meets the following requirements： .Allow administrators to manually approve patches and security updates .Allow only the installation of approved patches and security updates 
.Minimize the administrative effort to deploy patches .Minimize the deployment costs
What should you include in the solution？（）

You have an Exchange Server 2010 organization. 
The organization contains two servers named Server1 and Server2. 
Server1 and Server2 have the Mailbox server role and the Hub Transport server role installed. Server 1 and Server2 are members of a database availability group （DAG）. 
You need to plan the deployment of Client Access servers to meet the following requirements： .Users must be able to access their mailboxes if a single server fails .Users must not attempt to connect to a failed server 
What should you include in your plan？（）

You deploy multiple Mailbox servers. 
Each Mailbox server contains a copy of a mailbox database named DB1. 
You need to recommend a solution that allows administrators to remove corrupt messages that have beenreplicated before the corrupt messages are applied to each copy of DB1.
