You are the systems administrator for your company. The company’s network consists of a single Active Directory domain. The network contains a server running Exchange Server 2007. You want to migrate the existing Exchange Server 2007 computer to Windows Essential Business Server (EBS) 2008.
What should you do before performing the migration? (Choose two. Each correct answer presents part of the solution.)
A.
Ensure that the Domain Name System (DNS) role is migrated to Windows EBS.
B.
Ensure that the Dynamic Host Configuration Protocol (DHCP) role is migrated to Windows EBS.
C.
Ensure that the Active Directory Domain Services (AD DS) role is migrated to Windows EBS.
D.
Ensure that the existing Exchange server is decommissioned.
Explanation:
You should ensure that the DNS and DHCP roles are migrated to Windows EBS. When you perform the migration of Exchange Server 2007 to Windows EBS, it enables the users to take advantage of the new security and monitoring features that are provided by Windows EBS along with all the features in Exchange Server 2007. Before migrating Exchange Server 2007 to Windows EBS, you must migrate the DNS and DHCP roles to Windows EBS.You should not ensure that the AD DS role is migrated to Windows EBS because this is not a required step to be performed before migrating Exchange Server 2007 to Windows EBS.
You should not ensure that the existing Exchange server is decommissioned because this step must be performed after migrating Exchange Server 2007 to Windows EBS. You should only decommission the existing Exchange server when the replacement server is properly implemented.
