You have a computer that has the disk configuration shown in the following table.
You need to configure a storage space that will provide data redundancy if a disk fails. The solution
must minimize impact if a disk fails. Which resiliency type should you choose?
A.
three-way mirror
B.
two-way mirror
C.
simple
D.
parity

Why not parity in this case? It takes 3 disks and this would be the perfect question and scenario to ask this in, as if one disk fails impact is minimized. The mirror would still leave a free disk.

This is a stupid question… They only say that you need data redundancy. You can use Parity, two-way mirror and even three-way mirror (in this case we have 3 disks)
Three-way mirror –> Not very effecient
Simple –> Not redundant
Two-way mirror –> redundant, but you leave 1 disk unused.
Parity –> Redendant, use all disks
I would say that D is the best answer

two way mirror and 3rd one as a spare one?

two way mirror.
3 way reqs 5 disks so not an option.
parity is possible but if you lose a disk it causes a greater impact on system due to having to recreate data using the parity, whereas a disk lost in a mirror doesnt affect speed at all.
It is also quicker to recreate a failed mirror than a parity set.
Therefore a mirror minimizes the impact of failure better than parity
