Your company has an Azure Active Directory (Azure AD) tenant that is configured for hybrid coexistence with the on-premises Active Directory domain.
The on-premise virtual environment consists of virtual machines (VMs) running on Windows Server 2012 R2 Hyper-V host servers.
You have created some PowerShell scripts to automate the configuration of newly created VMs. You plan to create several new VMs.
You need a solution that ensures the scripts are run on the new VMs.
Which of the following is the best solution?

A. Configure a SetupComplete.cmd batch file in the %windir%setupscripts directory.

B. Configure a Group Policy Object (GPO) to run the scripts as logon scripts.

C. Configure a Group Policy Object (GPO) to run the scripts as startup scripts.

D. Place the scripts in a new virtual hard disk (VHD).








 

Suggested Answer: A

After you deploy a Virtual Machine you typically need to make some changes before it's ready to use. This is something you can do manually or you could use
Remote PowerShell to automate the configuration of your VM after deployment for example.
But now there's a third alternative available allowing you customize your VM: the CustomScriptextension.
This CustomScript extension is executed by the VM Agent and it's very straightforward: you specify which files it needs to download from your storage account and which file it needs to execute. You can even specify arguments that need to be passed to the script. The only requirement is that you execute a .ps1 file.
