You have a server named Server1 that runs Windows Server 2012 R2.
You connect two new hard disks to Server1.
You need to create a storage space that contains the two disks.
The solution must meet the following requirements:
Provide fault tolerance if a single disk fails.
Maximize the amount of files that can be stored in the storage space.
What should you create?
A.
a parity space
B.
a simple space
C.
a spanned volume
D.
a mirrored space

Answer is A:
Mirror Spaces: Stripes and mirrors data across a set of pool disks, supporting a two-way or three-way mirror, which are respectively resilient to single disk, or double disk failures. Suitable for the majority of workloads, in both clustered and non-clustered deployments.
Parity Spaces: Stripes data across a set of pool disks, with a single disk write block used to store parity information, and is resilient to a single disk failure. Suitable for large block append-style workloads, such as archiving, in non-clustered deployments.

Answer is D.
You only have 2 disks. Parity is not possible with only 2 disks. Parity (aka RAID 5) needs a minimum of 3 disks (2 data disks, and 1 disk for parity).
With 2 disks, the only way to provide fault tolerance is by using a mirror.
