You have a server named Server1 that runs Windows Server 8.
You connect three new hard disks to Server1.
You need to create a storage space that contains the three 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 simple space
B.
A spanned volume
C.
A mirrored space
D.
A parity space
Explanation:
A.Stripes data across a set of pool disks, and is not resilient to any disk failures. B.A spanned volume is a
dynamic volume consisting of disk space on more than one physical disk and not fault tolerant
C: Fault tolerant but Not max space
D: Fault tolerant and better space ratio

What are the best uses of simple, mirror, and parity spaces?
Storage Spaces offers simple spaces, mirror spaces, and parity spaces, each with unique characteristics.
•Simple spaces are designed for increased performance when resiliency isn’t very important. They are best suited for temporary data, such as video rendering files, image editor scratch files, and intermediary compiler object files. Simple spaces require a minimum of one physical disk.
•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. They are well suited to storing a broad range of data, from a general-purpose file share to a VHD library. When a mirror space is formatted with the Resilient File System (ReFS), Windows offers automatic data integrity maintenance. This is a layer of resiliency is above and beyond the resiliency achieved from maintaining multiple data copies to tolerate drive failure. This storage layout requires at least two disks to protect you from a single disk failure, or at least five disks to protect you from two simultaneous disk failures.
•Parity spaces are designed for capacity efficiency and increased resiliency. Parity spaces are best suited for archival data and streaming media, such as music and videos. This storage layout requires at least three disks to protect you from a single disk failure and at least seven disks to protect you from two disk failures.
