Your company network has an Active Directory forest that has one parent domain and one
child domain. The child domain has two domain controllers that run Windows Server 2008.
All user accounts from the child domain are migrated to the parent domain. The child domain
is scheduled to be decommissioned.
You need to remove the child domain from the Active Directory forest.
What are two possible ways to achieve this goal? (Each correct answer presents a complete
solution. Choose two.)
A.
Run the Computer Management console to stop the Domain Controller service on both
domain controllers in the child domain.
B.
Delete the computer accounts for each domain controller in the child domain. Remove the
trust relationship between the parent domain and the child domain.
C.
Use Server Manager on both domain controllers in the child domain to uninstall the Active
Directory domain services role.
D.
Run the Dcpromo tool that has individual answer files on each domain controller in the
child domain.
