You have a Windows Server 2016 Hyper-V failover cluster that contains two nodes named Node1 and Node2.
On Node1, you create a virtual machine named VM01 by using Hyper-V Manage.
You need to configure VM01 to move to Node2 automatically if Node1 becomes unavailable. What should you do?
A. From Failover Cluster manager, run the configure Role actions.
B. From Hyper-V Manager, click VM01 and click Enable Replication.
C. From Hyper-V Manager Click Node 1 and the modify the hyper-V settings.
D. From Windows Powershell, run the Enable-VMReplication cmdlet.
A should be correct
I’d say that A is better answer than D. Only running Enable-VMReplication cmdlet would not do the job since Node1 and Node2 are part of cluster. (If the servers are part of a failover cluster, you must configure the Hyper-V Replica
Broker role and make note the client access point name.)
Running Configure Role form Failover Cluster Manager would be more complete answer and action to do.
