Your network contains an Active Directory forest named contoso.com.
The forest contains the domain controllers configured as shown in the following table.
You plan to deploy an Exchange Server 2013 organization to the forest
A company policy prevents administrators from logging on to DC2 to perform installations.
You need to prepare the Active Directory schema for the planned Exchange Server deployment.
You verify that your user account has all the required permissions to achieve the task. The solution must
minimize changes to the Active Directory infrastructure.
A.
Move the schema master role to DC1, and then run Exchange setup.
B.
Deploy a member server to contoso.com, and then move the server to the West site. Run adprep.exe from
the member server.
C.
Log on to DC3 and then run Exchange setup.
D.
Log on to any server in the West site, and then run Exchange setup.
Explanation:
Prepare Active Directory and domains for Exchange 2013.
The first step in getting your organization ready for Exchange 2013 is to extend the Active Directory schema.
Exchange stores a lot of information in Active Directory but before it can do that, it needs to add and update
classes, attributes, and other items.
Before you extend your schema, there are a few things to keep in mind:
* The only way to extend the schema for Exchange is to use Setup.exe in Windows Command Prompt or use
Exchange 2013 Setup. Other ways of extending the schema aren’t supported.
* The computer where you’ll run the command to extend the schema needs to be in the same Active Directory
domain and site as the schema master. We can accomplish this be by moving the schema master role to DC,
and then run Exchange setup.
Incorrect answers:
Not B: Adprep is used to upgrade the Active Directory infrastructure forest to a newer version such as to
Windows Server 2008. Adprep is not used for Exchange Server infrastructure changes.
Not C: Exchange Setup must be run from the Schema master. DC3 does not have the schema master role.
Not D: Only DC2 in the West site has the Schema master role. We cannot run Exchange Setup from the other
servers in the West site.
