Yournetwork contains an Active Directory domain named contoso.com.
All domain controllers run Windows Server 2012 R2. The domain contains two domain controllers.
The domain controllers are configured as shown in the following table.
The Branch site contains a perimeter network.
For security reasons, client computers in the perimeter network can communicate with client
computers in the Branch site only.
Youplan to deploy a new RODC to the perimeter network in the Branch site.
Youneed to ensure that the new RODC will be able to replicate from DC10.
What should you do first on DC10?
A.
Run the Add-ADDSReadOnlyDomainControllerAccount cmdlet.
B.
Create an Active Directory site.
C.
Run the Active Directory Domain Services Configuration Wizard.
D.
Create an Active Directory subnet.
Explanation:
Add-ADDSReadOnlyDomainControllerAccount Creates a read-only domain controller (RODC)
account that can be used to install an RODC in Active Directory.
Note:
* Notes
Once you have added the RODC account, you can add an RODC to a server computer by using the
Install-ADDSDomainController cmdlet with the -ReadOnlyReplica switch parameter.
* Example
Adds a new read-only domain controller (RODC) account to the corp.contoso.com domain using the
North America site as the source site for the replication source domain controller.
C:\PS>Add-ADDSReadOnlyDomainControllerAccount -DomainControllerAccountName RODC1 –
DomainName corp.contoso.com -SiteName NorthAmerica Incorrect:
Not B: There already is a branch site. Add-ADDSReadOnlyDomainControllerAccount
Ans. C as you cannot replicate from RODCs

It’s A, read the example and also see below…
“Add-ADDSReadOnlyDomainControllerAccount -ReplicationSourceDC
Specifies the name of the domain controller to be used as the source for replicating to this RODC.”

This can’t be true, because the DC you specify, must be an Writable DC.
Which DC10 is not. And the question is: “You need to ensure that the new RODC will be able to replicate from DC10”

Sorry, just seen this-it states “What should you do first on DC10?”
I thought it said DC1.
So..lol, the answer is actually C. Why? Because you cannot replicate from RODC’s, you would need first to demote DC10 to a writable DC to be able to replicate from DC10.

There’s also this same quesiton, with different answer choices, but still same answer:

I see this ? on pretty much every dump. They all have Create an Active Directory Site Bridge as the answer. I would think it is Run the ADDS Config wizard but…
How do you use that tool to convert from an RODC to writable? I can’t see any way to do it.

I believe the question is implying that you need to demote the RODC with the Active Directory Domain Services configuration wizard and then you can promote it again to a full DC.
