Your network contains an Active Directory forest. The forest contains a single domain named
contoso.com. The domain contains four domain controllers.
The domain controllers are configured as shown in the following table.
All domain controllers are DNS servers.
You plan to deploy a new domain controller named DC5 in the contoso.com domain.
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 should you identify?
A.
DC1
B.
DC2
C.
DC3
D.
DC4
Explanation:
To perform a domain controller promotion you need the Infrastructure master to be online.
The schema master and the domain naming master are per-forest roles. Therefore, there is
only one schema master and one domain naming master per forest.
The RID master, the PDC master, and the infrastructure master are per-domain roles. Each
domain has its own RID master, PDC master, and infrastructure master. Therefore, if a
forest has three domains, there are three RID masters, three PDC masters, and three
infrastructures masters.
Incorrect answers:
A: The domain naming master Flexible Single Master Operations (FSMO) role holder is
assigned to the domain controller that is responsible for making changes to the
CN=Partitions,CN=Configuration, DC=domain configuration container in Active Directory
B: Active Directory Users and Computers Snap-in will always contact the PDC when User
Properties is opened
D: very Exchange Server 5.5 site or Exchange 2000 Server Routing Group needs a Routing
Information Daemon (RID) master, or routing master. This RID master generates the routing
table for the rest of the site (or Routing Group), which replicates to the entire Exchange
Server organization. By default the RID master is the first Exchange Server computer in the
site.

I am not convinced of the answer here, my gut wants to say DC4 due to what I read here:
http://support.microsoft.com/kb/223346 – RID 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.
Happy to be proven wrong however.

Answer is D [DC4 (RID master)]

I just tested trying to promote a Win2012 R2 server. You will get the following message when the the RID server is offline.
Verification of prerequisites for Domain Controller promotion failed. You cannot install an additional domain controller at this time because the RID master SYD-DC.Contoso.com is offline.
With only the RID Master available, you can promote the server. There are lots of sites/posts claiming that you need the Domain Naming Master. That is not correct.

holy shit who is guessing at these? If they had answered “banana” it would have been more correct than a 20 year old reference to Exchange or Netware directory services

I think RID Master (D) is the correct answer.
