Your network contains an Active Directory forest named contoso.com. The forest contains a single domain. The
domain contains two domain controllers named DC1 and DC2 that run Windows Server 2012 R2.
The domain contains a user named User1 and a global security group named Group1.
You reconfigure DC2 as a member server in the domain.
You need to add DC2 as the first domain controller in a new domain in the forest.
Which cmdlet should you run?

A.
Add-AdPrincipalGroupMembership

B.
Install-AddsDomainController

C.
Install WindowsFeature

D.
Install AddsDomain

E.
Rename-AdObject

F.
Set AdAccountControl

G.
Set-AdGroup

H.
Set-User

Explanation:
Since a member server does not have Active Directory Domain Services installed, you must install this role
before you can configure the new Domain Controller (which would require you to run Install-ADDSForest).
