A corporate environment includes Exchange Server 2003 SP2 and an Active Directory Domain
Services (AD DS) forest with two domains. The forest functional level is set to Windows 2000. The
domain functional level of Domain1 is set to Windows 2000 mixed. The domain functional level of
Domain2 is set to Windows 2000 native. The AD DS infrastructure is shown in the following table.

Windows Server 2003 SP1 domain controllers. You need to recommend a solution for preparing the
existing AD DS infrastructure to support Exchange Server 2010 SP1. Which two actions should you
recommend? (Each correct answer presents part of the solutions. Choose two.)
