Contoso, Ltd. has an Exchange Server 2010 environment that accepts email for the contoso.com email domain. Fabrikam, Inc. has an Exchange Server 2010 environment that accepts mail for the fabrikam.com email domain. Contoso acquires Fabrikam and establishes an internal network connection between the two companies. After the acquisition, only the Contoso Exchange Server environment accepts external email. You have the following requirements:

* Retain existing fabrikam.com email addresses.
* Enable users in both Exchange Server environments to receive mail at contoso.com email addresses.

You need to recommend a solution that meets the requirements.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A corporate environment will include client computers that run Microsoft Outlook 2010. Email services will be provided to some users by a cloud-based Exchange Server 2010 SP1 service provider and to other users by an on-premise deployment of Exchange Server 2010 SP1. You need to recommend a solution that will allow users in the cloud-based environment to receive internal Out of Office replies from users in the on-premise environment.

What should you recommend?

Your company has a main office and 10 branch offices. Each office has a direct link to the Internet. Each branch office has a WAN link that connects to the main office. Your network consists of an Active Directory forest. Each office is configured as an Active Directory site. You plan to deploy an Exchange Server 2010 Hub Transport server in each site. You need to design a message routing solution to meet the following requirements:

* Branch office connections to the Internet must be used to deliver e-mail
* Branch office servers must use the WAN link to the main office to deliver e-mail to other branch offices
* Branch office servers must be prevented from sending e-mail to the Internet by using the WAN link to the main office
* The solution must minimize administrative overhead

What should you include in the solution?

You have a main office and five branch offices. The offices connect to each other by using a WAN link. An Active Directory site exists for each office. Each site has a separate IP site link to all other sites. The main office site is configured as a hub site. You have an Exchange Server 2010 organization. You discover that messages sent between offices are not routed through the Hub Transport servers in the main office. You need to ensure that all messages sent between offices are routed through the Hub Transport servers in the main office.

What should you do?

You have an Exchange Server 2010 Hub Transport server named Hub1. You install an application on a third-party server named Server1. You discover that the application cannot authenticate to remote servers. You need to ensure that the application can relay e-mail messages by using Hub1.

What should you do?

You are designing an Exchange organization for a company named Contoso, Ltd. All servers in the organization will have Exchange Server 2010 Service Pack 1 (SP1) installed. Contoso has a partner company named Fabrikam, Inc. Fabrikam has an Exchange organization that contains only Exchange Server 2010 SP1 servers. You plan to configure a federation trust between Fabrikam and Contoso.

You need to recommend a certificate for the federation trust.
Which of the following certificates is the best recommendation? (More than one answer choice may achieve the goal. Select the BEST answer.)

A corporate environment will include Exchange Server 2010 in a single Active Directory Domain Services (AD DS) domain. The primary DNS suffix of the domain controllers is not the same as the DNS domain name. You are designing the Exchange Server 2010 deployment plan. You need to recommend a solution that allows Exchange Server 2010 servers to access the domain controllers.

What should you recommend?

A corporate environment includes an on-premise deployment of Exchange Server 2010 SP1 and an Active Directory Domain Services (AD DS) domain. The company plans to move some users to a cloud-based Exchange Server 2010 SP1 environment. The migration process must meet the following requirements:

* Integrate the on-premise environment with the cloud-based environment.
* Migrate all existing mailbox items.
* Authenticate all users by using their AD DS credentials.
* Share calendar availability information among all users.

You need to recommend a tool for gathering information and verifying that the requirements can be met.
Which tool should you recommend?

A corporate environment includes an on-premise deployment of Exchange Server 2010 SP1. The company needs to share calendar availability information with a partner. The partner is using a cloud-based Exchange Server 2010 SP1 service. You need to recommend a solution for sharing calendar availability information for all employees with the partner.

What should you recommend?

Your company has three offices. Each office has a direct link to the Internet. The offices connect to each other by using a WAN link. Your network consists of an Active Directory forest that contains two domains and one site. The functional level of the forest is Windows Server 2003. All domain controllers run Windows Server 2003 R2. Each office contains two domain controllers for each domain. All domain controllers are global catalog servers. In each office, you plan to deploy Mailbox,
Client Access, and Hub Transport Exchange Server 2010 servers. All e-mail messages sent to the Internet will be delivered from a local server in each office. You need to recommend changes to the Active Directory environment to support the planned deployment of Exchange Server 2010.
