DRAG DROP
You have a computer that runs Windows 8. You have a 1-terabyte external hard drive. You purchase
a second 1-terabyte external hard drive. You need to create a fault-tolerant volume that includes
both external hard drives. You also need to ensure that additional external hard drives can be added
to the volume. Which three actions should you perform in sequence? (To answer, move the
appropriate actions from the list of actions to the answer area and arrange them in the correct order.)
Answer: 
Explanation:
Box 1: Back up the existing data on your old USB drive.
Box 2: From Control panel, use Storage Spaces to create a new pool. Set Resiliency Type to two-way mirror.
Box 3: Restore your data from the backup.
Note:To create a storage space, you’ll have to connect two or more additional drives to your computer –
you can’t use your system drive for this. The drives can be either internal or external drives.
You can open the Storage Spaces configuration window from the Control Panel or by bringing up the
Start screen with the Windows key, typing “Storage Spaces,” clicking the Settings category and
selecting the Storage Spaces shortcut.
Select the drives you want to use for the storage space and click the “Create pool” button to
continue. You’ll lose any files that are already on the drive – copy any important files off the drives
before pooling them. You can add additional drives later.
The resiliency type controls how Windows handles your data.
There are four options:
* None: Windows will store only a single copy of your . You’ll lose the data if one of your drives fails,
but no space will be used on backups.
* Two-way mirror: Windows will store two copies of your data. If one of your drives fails, you won’t
lose your data. This requires at least two drives.
* Three-way mirror: Windows will store three copies of your data. If one or two of your drives fails,
you won’t lose your data. This requires at least three drives.
* Parity: Windows stores parity information with the data, protecting you from a single drive failure.
Parity uses drive space more efficiently than mirroring, but file access times are slower. Parity is ideal
for drives with large, infrequently updated files, such as video files.
