All virtual machines must be highly available.
You need to configure the environment.
What should you implement?
A. a separate Hyper-V replica between NYC-Host1 and SFC-Host1
B. a Hyper-V cluster that includes NYC-Host1, NYC-Host2, and SFC-Host1
C. a Hyper-V cluster between NYC-Host1 and SFC-Host1
D. a Hyper-V replica between NYC-Host1 and NYC-Host2 with an extended replica between NYC-Host1 and SFC-Host1
Correct Answer: D

Role/Feature description
Hyper-V Replica provides asynchronous replication of Hyper-V virtual machines between two hosting servers. It is simple to configure and does not require either shared storage or any particular storage hardware. Any server workload that can be virtualized in Hyper-V can be replicated. Replication works over any ordinary IP-based network, and the replicated data can be encrypted during transmission. Hyper-V Replica works with standalone servers, failover clusters, or a mixture of both. The servers can be physically co-located or widely separated geographically. The physical servers do not need to be in the same domain, or even joined to any domain at all.
