You are configuring a twonode failover cluster. The failover cluster will connect to a storage server that runs Windows Storage Server 2008. The storage server contains a raw disk. The raw disk appears in the Disk Management console for both nodes. From one of the nodes, you bring the disk online, and then you initialize the disk. You run the Validate a Configuration Wizard as shown in the exhibit.

You need to ensure that all of the tests pass when you run the Validate a Configuration Wizard.

What should you do?

A.
Convert the disk to a GPT disk, and then create a simple volume.

B.
Convert the disk to a dynamic disk, and then take the disk offline.

C.
Create a simple volume on the disk, and then take the disk offline.

D.
Create a simple volume, and then convert the disk to a dynamic disk.

Explanation:
Now we should see our newly formatted disk as online in Disk Management. Note that if you went to any other node in the cluster, we’d still show this disk as ‘offline’. This is good because we don’t want more than one node to be able to see or access a disk until it’s under the control of the cluster. That’s the step we do next.
