Which two PowerShell cmdlets should you run in the script?

You have 20 servers that run Windows Server 2012 R2.
You need to create a Windows PowerShell script that registers each server in Windows
Azure Backup and sets an encryption passphrase.
Which two PowerShell cmdlets should you run in the script? (Each correct answer presents
part of the solution. Choose two.)

A.
Set-OBMachineSetting

B.
Add-OBFileSpec

C.
Start-OBRegistration

D.
New OBPolicy

E.
New-OBRetentionPolicy

Explanation:
Registers the current computer with Windows Azure Online Backup using the credentials
(username and password) created during enrollment.
E: The Set-OBMachineSetting cmdlet sets a OBMachineSetting object for the server that
includes proxy server settings for accessing the internet, network bandwidth throttling
settings, and the encryption passphrase that is required to decrypt the files during recovery
to another server.
Incorrect:
Not C: The Add-OBFileSpec cmdlet adds the OBFileSpec object, which specifies the items
to include or exclude from a backup, to the backup policy (OBPolicy object). The
OBFileSpec object can include or exclude multiple files, folders, or volumes. T
