    Company.com has a three-node cluster （Node ’A’， Node ’B’， and Node ’C’） with three resource  Groups （rg1， rg2， and rg3）. Node ’A’ has twice as many CPUs and twice as much memory as the two test add development Nodes ’B’ and ’C’. During normal production processing， all resource groups are active on Node ’A’.  What is most efficient way to configure the cluster to manage the workload？（）
    A

     Use thee cascading resource groups where ’rg1’ and ’rg2’ fallover to Node ’B’ and ’rg3’ falls over to Node ’C’

    B

     Use Dynamic Node Priority resource groups with a priority chain consisting of Node ’A’ then Node ’B’ then Node ’C’

    C

     Use three rotating resource groups with ’rg1’ and ’rg2’ falling over to node ’B’ and ’rg3’ falling over to Node ’C’

    D

     Upgrade Nodes ’B’ and ’C’ to be equal to Node ’A in CPU and memory resources to enable the cluster to synchronize three resource groups
