Your company has two main offices and 10 branch offices. Each office is configured as a separate Active Directory site.
The main offices sites are named Site1 and Site2. Each office connects to Site1 and Site2 by using a WAN link. Each site contains a domain controller that runs
Windows Server 2008.
You are redesigning the Active Directory infrastructure.
You plan to implement domain controllers that run Windows Server 2012 and decommission all of the domain controllers that run Windows Server 2008.
You need to recommend a placement plan for the Windows Server 2012 domain controllers to meet the following requirements:
Ensure that users can log on to the domain if a domain controller or a WAN link fails.
Minimize the number of domain controllers implemented.
What should you include in the recommendation? (Each correct answer presents part of the solution. Choose all that apply.)
A.
Read-only domain controllers (RODCs) in the branch office sites
B.
A writable domain controller in Site1
C.
A writable domain controller in Site2
D.
Writable domain controllers in the branch office sites
Explanation:
A (not D) Writeable domain controllers are not needed to authenticate users at the branch offices.
The question says if a domain controller or WAN link fails, which is singular. Since they are two main offices and you want to minimize the amount of DCs. I would go with B&C.

This question is not worded well. Just because the branch offices have a connection to Site1 and 2, does not mean a branch has two WAN connections. It is very typical with MPLS connections that you have one WAN connection to your site but through your one WAN connection you are able to directly connect to multiple sites (if setup with mesh topology). IF this is the case than if the WAN goes down at the branch office, you lost connection to both Site1 and 2. This means the given answer is correct.
