DRAG DROP
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.)
Answer: See the explanation
Explanation:
Explanation/Reference
Box 1: Add five physical disks.
Box 2: Create a storage space by using the default disk allocation.
Box 3: Create a virtual disk.
Box 1: Add five physical disks.
Box 2: Create a storage space and set the disk allocation of one of the disks to hot Spare.
Box 3: Create a virtual disk.
To sustain 2 disk failures you need to create a storage pool with 4 disks and then the 5th disks will be used as a hot spare.

Ill throw a wrench in this response.
3 Disks
1 Hot spare
Default allocation
2 disks with mirror and a hot spare tolerates 2 disk failure.

Actually, I found another proof for the argument of the site with default configuration…
See: http://social.technet.microsoft.com/wiki/contents/articles/11382.storage-spaces-frequently-asked-questions-faq.aspx
This states the following:
>>>
Mirror spaces are designed for increased performance and increased resiliency. Two-way mirror spaces can tolerate one disk failure and three-way mirror spaces can tolerate two disk failures.
Mirror spaces require at least two disks (per tier if you use storage tiers) to protect you from a single disk failure. To protect a virtual disk from two simultaneous disk failures, you need at least three disks (per tier), with a minimum of five disks total in the pool to maintain pool metadata.

So no hot-spare configuration needed… So I'd go for the answer provided by the website:
Box 1: Add five physical disks.
Box 2: Create a storage space by using the default disk allocation.
Box 3: Create a virtual disk.
