You have a server that runs Windows Server 2012 R2.
You need to create a volume that will remain online if two disks in the volume fail. The solution must minimize the number of disks used to create the volume.
Which three actions should you perform in sequence? (To answer, move the appropriate three actions from the list of actions to the answer area and arrange them
in the correct order.)
Select and Place:
Answer: 
Explanation:
Box 1: Add five physical disks.
Box 2: Create a virtual disk.
Box 3: Create a storage space by using the default disk allocation.
Windows Server 2012 R2 R2 introduces a parallelized repair process, where the remaining healthy disks move around and take responsibility for the slabs of data
that were stored on the failed disk. It is extremely quick because all disks in the storage space are involved. The recommendation is that instead of using hot
spares, you instead use the disks that are spare but active capacity in the storage space, that can be availed of by the parallelized repair process. This will both offer
more IOPS to normal production storage activity and leave your business less vulnerable during a repair process
Box 1: Add five physical disks.
Box 2: Create a storage space by using the default disk allocation.
Box 3: Create a virtual disk.

Isn’t a Storage Space the same thing as a virtual HDD?

“Storage spaces. Virtual disks created from free space in a storage pool.”

Because to build volume that will survive 2 disks failure you need to utilize Three-Way-Mirroring, which requires 5 disks.
