Your network contains an Active Directory forest. The forest contains a single domain named
contoso.com and corp.contoso.com. The forest contains four domain controllers.
The domain controllers are configured as shown in the following table.
All domain controllers are DNS servers.
In the corp.contoso.com domain, you plan to deploy a new domain controller named DC5.
You need to identify which domain controller must be online to ensure that DC5 can be promoted
successfully to a domain controller.
Which domain controller identify which domain controller must be online to ensure that DC5 can be
promoted successfully to a domain controller.
Which domain controller should you identify?
A.
DC1
B.
DC2
C.
DC3
D.
DC4
Explanation:
In order to add a Domain Controller to corp.contoso.com, you need PDC and RID of that domain, not
of the root domain. The Domain Naming Master is needed to add, remove and rename domains in
the forest, i.e. not for individual Domain Controllers.
I think the answer is A this is according to the following article…
https://technet.microsoft.com/en-us/library/cc780487(v=ws.10).aspx
Domain membership of the domain controllers is not available in this question therefore there is insufficient information to answer this question. the PDC Emulator and the RID Master of the respective domain needs to be available to join a server to a domain and to promote to DC
D.
RID
“Allocates active and standby RID pools to replica domain controllers in the same domain.
Must be online for newly promoted domain controllers to obtain a local RID pool that is required to advertise or when existing domain controllers have to update their current or standby RID pool allocation.”
