You host several virtual machines on a Windows Server 2008 R2 Hyper-V failover cluster.
You are deploying a highly available virtual machine (HAVM) that supports live migration.
You need to install the operating system in the appropriate location. What are two possible
locations that will allow you to achieve this goal? (Each correct answer presents a complete
solution. Choose two.)

A.
a pass-through disk on a Fibre Channel logical unit number (LUN)

B.
a pass-through disk on a direct-attached storage (DAS)

C.
a VHD on an iSCSI logical unit number (LUN)

D.
a VHD on network-attached storage (NAS)

Explanation:
Microsoft does not support network-attached storage (NAS) for Hyper-V. We can not present
a DAS type of storage disk to the remote server, only locally it is supported.
