You are a desktop support engineer for an advertising company that uses Windows 8.1 workstations.
An employee who manages video content for the company website recently lost important video
files due to a single-drive failure on a Windows 8.1 workstation.
You need to prevent a single-drive failure from occurring again on this employee’s workstation,
which only has a capacity for three physical hard drivers. Additionally, the employee requires
optimal performance when manipulating and streaming video files.
Which Storage Space solution should you implement?

A.
three-way mirror

B.
parity spaces

C.
simple spaces

D.
two-way mirror

Explanation:
Parity spaces (also known as RAID-5) are designed for storage efficiency and protect your files from
drive failure by keeping more than one copy. Parity spaces are best for archival data and streaming
media, like music and videos. This storage layout requires at least three drives to protect you from a
single drive failure and at least seven drives to protect you from two drive failures.
