What should you recommend?

Your network contains two data centers named DataCenter1 and DataCenter2. The two data centers
are connected by using a low-latency high-speed WAN link.
Each data center contains multiple Hyper-V hosts that run Windows Server 2012. All servers connect
to a Storage Area Network (SAN) in their local data center.
You plan to implement 20 virtual machines that will be hosted on the Hyper-V hosts.
You need to recommend a hosting solution for the virtual machines.
The solution must meet the following requirements:
Virtual machines must be available automatically on the network if a single Hyper-V host fails.
Virtual machines must be available automatically on the network if a single data center fails.
What should you recommend?

A.
One failover cluster in DataCenter1 and Hyper-V replicas to DataCenter2

B.
One failover cluster in DataCenter2 and one DFS Replication group in DataCenter1

C.
One failover cluster that spans both data centers and SAN replication between the data centers

D.
One failover cluster and one Distributed File System (DFS) Replication group in each data center
