Your network includes Windows Server 2008 R2 Hyper-V servers. You are configuring the servers in a failover cluster that will host highly available virtual machines （HAVMs）. You plan to manage the servers in the cluster by using Microsoft System Center Virtual Machine Manager （VMM） 2008 R2. You need to design a storage solution for the cluster that allows you to migrate virtual machines （VMs） into and out of the cluster by using SAN migration. Which two actions should you include in your design？（）

• A、Install a Virtual Disk Service （VDS） hardware provider on each node in the cluster
• B、Enable the auto mount feature on each node in the cluster
• C、Place all VMs on a dedicated logical unit number （LUN）
• D、Place all VMs on a single Cluster Shared Volume （CSV）
