Your network contains one Active Directory forest that has a root domain and three child domains. All domain controllers run Windows Server 2003 Service Pack 1 (SP1). Each domain has a different password policy.
The domain is configured as shown in the exhibit. (Click the Exhibit button.)
You plan to reduce the number of domains in the forest.
You need to plan the restructuring of the forest to meet the following requirements:
Maintain all existing password policies.
Maintain all existing user account attributes.
What should you include in your plan?
A. Upgrade all domains to Windows Server 2008. Redirect the users container in the root domain by using the redirusr.exe tool, and then remove the child domains. Enable fine-grained password policies.
B. Upgrade all domains to Windows Server 2008 and enable SID history. Move all user accounts from the child domains to the root domain by using the movetree.exe tool, and then remove the child domains.
C. Upgrade the forest root domain to Windows Server 2008. Use the Active Directory Migration Tool (ADMT) to migrate user accounts that contain SID history from the child domains to the forest root domain. Remove the child domains.
D. Upgrade the forest root domain to Windows Server 2008. Use the Active Directory Migration Tool (ADMT) to migrate user accounts from the child domains to the forest root domain, and then remove the child domains. Enable fine-grained password policies.
