You have to deploy a new application to an Azure Windows virtual machine using the Desired State Configuration extension. Which of the following are steps that need to be followed to implement the Desired State Configuration?

Answer options:

A.Store the PowerShell configuration file in an Azure File share.
B.Store the PowerShell configuration file in an Azure Blob storage.
C.Create a YAML configuration file.
D.Create a PowerShell configuration file.
E.Configure the Custom Script Extension on the virtual machine.
F.Configure the DSC Extension on the virtual machine.

Answer – B, D and F 
First, you have to create the PowerShell configuration file. The PowerShell configuration needs to be stored in Azure Blob storage. 
Then create a DSC Extension on the virtual machine using the PowerShell configuration file. 
Option A is incorrect because you have to use Azure Blob storage and not Azure File Storage. 
Option C is incorrect because the configuration file needs to be in PowerShell. 
Option E is incorrect because we have to use DSC Extension and not the Custom Script Extension.
