What should you include in your design?

You plan to deploy a distributed database application that runs on multiple Windows Server 2008 R2 servers.
You need to design a storage strategy that meets the following requirements:
Allocates storage to servers as required.
Uses the existing network infrastructure.
Uses standard Windows management tools.
Ensures that data is available if a single disk fails.

What should you include in your design?

A.
An iSCSI disk storage subsystem that supports Microsoft Multipath I/O. Configure the storage subsystem as
a RAID 0 array.

B.
An iSCSI disk storage subsystem that supports Virtual Disk Service (VDS). Configure the storage
subsystem as a RAID 5 array.

C.
A Fibre Channel (FC) disk storage subsystem that supports Microsoft Multipath I/O. Configure the storage
subsystem as a RAID 0 array.

D.
A Fibre Channel (FC) disk storage subsystem that supports the Virtual Disk Service (VDS). Configure the
storage subsystem as a RAID 5 array.

Explanation:
iSCSI can be used without addition of hardware (in contrast to FC) in the existing network infrastructure.
To manage disks on a remote computer by using Disk Management (standard Windows management tool) on
the local computer, the remote computer must support the Virtual Disk Service (VDS).
RAID 5 (and RAID 1) provides high availability for disk storage.
