Suggested Answer: AD ūüó≥ÔłŹ
Virtual Machine Scale Sets can be used with the Azure Desired State Configuration (DSC) extension handler. Virtual machine scale sets provide a way to deploy and manage large numbers of virtual machines, and can elastically scale in and out in response to load. DSC is used to configure the VMs as they come online so they are running the production software.

A is for user. The other one, mmm. You can't create a vmss with a configuration script, in purpose of that you need a ARM template. There are no option for that, so the only near possibility is D. So answer is A & D

The answer is A & C in the question it states that "You plan to automate the deployment of a virtual machine scale set that uses the Windows Server 2016 Datacenter image" D defeats the purpose of the automation requirement, so C is 100% correct. Install an app with the Custom Script Extension The Custom Script Extension downloads and executes scripts on Azure VMs. This extension is useful for post deployment configuration, software installation, or any other configuration / management task. Scripts can be downloaded from Azure storage or GitHub, or provided to the Azure portal at extension run-time. https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-deploy-app#already-provisioned Also check this https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/tutorial-install-apps-template#what-is-the-azure-custom-script-extension

https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/tutorial-install-apps-template I have to agree with original answer, but I'm not happy about the frase "automate deployment" as we are creating the scaleset manually in the portal. With given answers, I would go for A and D

This is a correct answer. You have to create a scaleset since one is not mentioned to have been created already. You also have to adjust the ARM extensionProfile to add the DSC. Found answer here https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/dsc-template?toc=/azure/virtual-machines/windows/toc.json

I think there are 2 ways to achieve this: 1) Is to do it through Custom Script Extension (A). It can specify the script location & the command to run 2) Store the Configuration File & specify the location in Azure Template (C). This is specifically used when you have some sensitive data like certificate ( If you like HTTPS in website) So You don't need to do both...but for 2nd one..u still need to use the custom script extension...I think the questions are not worded properly https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/custom-script-windows

All, I have done this. You can create a script, upload to Azure and have your VM execute the script after the VM is built. If you were doing thru CLI, you would do something like this : az vm extension set \ --resource-group $RESOURCEGROUP \ --vm-name simpleLinuxVM \ --name customScript \ --publisher Microsoft.Azure.Extensions \ --version 2.0 \ --settings '{"fileUris":["https://raw.githubusercontent.com/MicrosoftDocs/mslearn-welcome-to-azure/master/configure-httpd.sh"]}' \ --protected-settings '{"commandToExecute": "./configure-httpd.sh"}' This means you need to tell the VM to run a script and you need to tell the VM-template where the script is. My answer is : A and C
