Your network contains an Active Directory domain named contoso.com. The domain
contains a member server named Server1. Server1 runs Windows Server 2012 R2 and has
the File and Storage Services server role installed.
On Server1, you create a share named Documents.
You need to ensure that users can recover files that they accidently delete from Documents.

What should you do?

A.
Enable shadow copies by using Computer Management.

B.
Create a storage pool that contains a two-way mirrored volume by using Server Manager.

C.
Modify the Startup type of the Volume Shadow Copy Service (VSS) by using the Services
console.

D.
Create a recovery partition by using Windows Assessment and Deployment Kit (Windows
ADK).

Explanation:
Shadow copies – a feature that provides point-in-time copies of files stored on file shares on
file servers. Shadow Copies of Shared Folders allows users to view and access shadow
copies, which are shared files and folders as they existed at different points of time in the
past. By accessing previous versions of files and folders, users can compare versions of a
file while working and recover files that were accidentally deleted or overwritten.
