You have an Active Directory forest that contains one domain named contoso.com. The functional level of both the forest and the domain is Windows Server 2003.
You have an Exchange Server 2003 organization. All servers have Exchange Server 2003 SP2 installed.
You plan to transition to Exchange Server 2010.
You need to prepare the Active Directory environment for the deployment of the first Exchange Server 2010 SP1 server.
What should you run?
A.
Setup.com /preparedomain
B.
Setup.com /preparead
C.
Setup.com /preparelegacyexchangepermissions
D.
Setup.com /prepareschema
Explanation:
/Preparedomain isn’t even a correct switch.You could argue that /preparelegacyexchangepermissions is also correct as this would be the first switch you would run if running them individually, followed by /prepareschema.
However /preparead will run /preparelegacyexchangepermissions and /prepareschema if it detects they have not been run.
