Which configuration should you use?

You administer all the deployments of Microsoft SQLServer 2012 in your company. You have two servers in
the same data center that hosts your production database. You need to ensure that the database remains
available if a catastrophic server failure or a disk failure occurs. You also need to maintain transactional
consistency of the data across both servers. You need to achieve these goals without manual intervention.

I think the correct answer is D. The Availability Group will require Synchronous-Commit, but I don’t see anywhere that it must be on the same subnet.

Well as the question says, your servers are in the same datacenter. Why make everything more complex. Its easier to stay in your same subnet and datacenter. As usual the Microsoft Exam Questions try to set you on the wrong track. And in this case you can use both answers, but you should pick the “more” correct one. So you should pick H!
