How should you configure Cluster1?

Your network contains two servers named Server1 and Server2.

The network contains a Storage Area Network (SAN).

Server1 and Server2 each connect to two logical unit numbers (LUNs) on the SAN.

You create a failover cluster named Cluster1. Server1 and Server2 are nodes in Cluster1. One of the LUNs is used as a witness disk.

You plan to create 10 virtual machine (VM) instances in Cluster1.

You need to ensure that each VM instance can be moved between nodes independently of the other VMs.

How should you configure Cluster1?

A.
Enable cluster shared volumes.

B.
Modify the quorum configuration.

C.
Create a clustered Generic Service instance.

D.
Create a clustered Microsoft Distributed Transaction Coordinator (MSDTC) resource.

Explanation:
Storage: You must use shared storage that is compatible with Windows Server 2008 R2.

A feature of failover clusters called Cluster Shared Volumes is specifically designed to enhance the availability and manageability of virtual machines. Cluster Shared Volumes are volumes in a failover cluster that multiple nodes can read from and write to at the same time. This feature enables multiple nodes to concurrently access a single shared volume. The Cluster Shared Volumes feature is only supported for use with Hyper-V and other technologies specified by Microsoft.

On a failover cluster that uses Cluster Shared Volumes, multiple clustered virtual machines that are distributed across multiple cluster nodes can all access their Virtual Hard Disk (VHD) files at the same time, even if the VHD files are on a single disk (LUN) in the storage. This means that the clustered virtual machines can fail over independently of one another, even if they use only a single LUN. When Cluster Shared Volumes is not enabled, a single disk (LUN) can only be accessed by a single node at a time. This means that clustered virtual machines can only fail over independently if each virtual machine has its own LUN, which makes the management of LUNs and clustered virtual machines more difficult.

For a two-node failover cluster, the storage should contain at least two separate volumes (LUNs), configured at the hardware level. Do not expose the clustered volumes to servers that are not in the cluster. One volume will function as the witness disk (described later in this section). One volume will contain the files that are being shared between the cluster nodes. This volume serves as the shared storage on which you will create the virtual machine and the virtual hard disk. To complete the steps as described in this document, you only need to expose one volume.

For Cluster Shared Volumes, there are no special requirements other than the requirement for NTFS.
For the partition style of the disk, you can use either master boot record (MBR) or GUID partition table (GPT).
