Drag and Drop Question
You have a Windows 10 Enterprise computer. 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:
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. When creating the pool, any existing data on the disks will be lost. It is
therefore important to back up the data if you do not want to lose it. 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 Two-way mirror resiliency type allows Windows to store two copies of
your data, so that you won’t lose your data if one of your drives fails.
