You purchase a new Windows 10 Enterprise desktop computer. You have four external USB hard
drives. You want to create a single volume by using the four USB drives. You want the volume to
be expandable, portable and resilient in the event of failure of an individual USB hard drive. You
need to create the required volume. What should you do?

A.
From Control Panel, create a new Storage Space across 4 USB hard drives.
Set resiliency type to Three-way mirror.

B.
From Control Panel, create a new Storage Space across 4 USB hard drives.
Set resiliency type to Parity.

C.
From Disk Management, create a new spanned volume.

D.
From Disk Management, create a new striped volume.

Explanation:
Storage Spaces can combine multiple hard drives into a single virtual drive. To create a storage
space, you’ll have to connect two or more additional internal or external drives to your computer to
create a storage pool. You can also specify an arbitrarily large logical size. When your existing
drive begins to fill up and nears the physical limit, Windows will display a notification in the Action
Center, prompting you to add additional physical storage space. Selecting the Parity resiliency type
allows Windows to store parity information with the data, thereby protecting you from a single drive
failure.

Incorrect Answers:
A: The Three-way mirror resiliency type allows Windows to store three copies of your data. Mirroring
uses drive space less efficiently than parity.
C: Spanned volumes are not fault tolerant
D: Striped volumes are not fault tolerant
