Which two actions should you perform?

You have a server named Server1. Server1 runs Windows Server 2012 R2 and has the File and Storage
Services server role installed.
You attach four 500-GB disks to Server1.
You need to configure the storage to meet the following requirements:
Storage for an application named Application1 must be provided. Application1 requires 20 GB and will
require a maximum of 800 GB in three years.
Storage for an application named Application2 must be provided. Application2 requires 20 GB and will
require a maximum of 900 GB in three years.
The solution must provide the ability to dynamically add storage without requiring configuration changes to
the applications.
The storage must be available if a single disk fails.
