You are the systems administrator for your company. The company has a main office and a branch office. The main office contains two domain controllers, named DC1 and DC2. The branch office contains two domain controllers, named DC3 and DC4. The network consists of a Windows Small Business Server (SBS) 2003 environment. You want to migrate from Windows SBS 2003 to Windows Essential Business Server 2008. Before performing the migration, you want to demote DC3 to a member server. You want to ensure that all Flexible Single Master Operations (FSMO) roles that are locally held by DC3 remain unassigned until you reassign them manually to another domain controller
Which command should you run?
A.
Run the Dcpromo.exe command with the /forceRemoval parameter.
B.
Run the Dcpromo.exe command with the /retainDCmetadata parameter.
C.
Run the Dcpromo.exe command with the /UseExistingAccount parameter.
D.
Run the Dcpromo.exe command with the /adv parameter.
Explanation:
You should run the Dcpromo.exe command with the /forceRemoval parameter. Dcpromo.exe is an executable program that is used to promote and demote Windows 2000 Server, Windows Server 2003, and Windows Server 2008 domain controllers. The /forceRemoval parameter forces the demotion of a domain controller. When you demote a domain controller with the /forceRemoval option, you will lose any unique changes that reside in the Active Directory of the domain controller that you are forcibly demoting. When you demote a domain controller by using Dcpromo /forceremoval command, the FSMO roles remain in an invalid state until they are reassigned by an administrator.You should not run the Dcpromo.exe command with the /retainDCmetadata parameter. The /RetainDCMetadata parameter retains the metadata of a domain controller in the domain after Active Directory removal to allow a delegated administrator to remove Active Directory from a read-only domain controller (RODC).
You should not run the Dcpromo.exe command with the /UseExistingAccount parameter. The /UseExistingAccount parameter attaches a server to an RODC account. This step is performed while installing an RODC.You should not run the Dcpromo.exe command with the /adv parameter. Running the Dcpromo /adv command launches the Active Directory Domain Services Installation Wizard in advanced mode. Running the Dcpromo /adv command will not ensure that all FSMO roles that are locally held by DC3 remain unassigned until you reassign them manually to another domain controller.
