Exam AZ-300 topic 1 question 15 discussion

A and E https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-deploy-app

C & E Look good. As the VM is native Azure image, it comes with the Azure VM agent on it that can be used to install and software. Custom scripts and extensions are needed when the default Azure VM agent is not enough. In this case, installing web server components is a native thing that can be done on the server so no custom script should be needed. https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/features-windows

Man this is confusing and reading through the comments isn't helping lol. My take on it is that it is C and E as well. I know it says that it is trying to automate the deployment of the scale set but wouldn't you need a scale set to start? If you just upload the configuration script with all the settings in it, how does it what image to use? Can you specify that you want a 2016 image?

Question is "plan to automate the deployment of a virtual machine scale set " - THen we assume that this is done using ARM template. If you are creating from portal there is no automation. When you create an ARM template for VSS - You create a bash script and modify the template's extension profile to execute that bash where the install something like ngnix as webserver - This bash script must be uploaded so in azure for automation. Its A and E

When you define a virtual machine scale set with an Azure template, the Microsoft.Compute/virtualMachineScaleSets resource provider can include a section on extensions. The extensionsProfile details what is applied to the VM instances in a scale set. To use the Custom Script Extension, you specify a publisher of Microsoft.Azure.Extensions and a type of CustomScript.

they have web server components is already installed. so C and E are correct.

C & E are correct.

A and E is the correct answer

A & C are correct... IF using DSC with the Scale Set, but they don't even mention DSC in the question, so... it's a badly expressed question.

Yes, I'm for C&E. There should no other possibilities

This question is tricky but the answer is CORRECT and here it is WHY. What the combination of the 2 answers implies is that you create the VMSS, then export it as a Resource Manager template. You add the webserver components to the template and then it is ready for automation.

C and E are correct.

C. Create a new virtual machine scale set in the Azure portal. E. Modify the extensionProfile section of the Azure Resource Manager template.

given answers [C&E] are correct. From the link provided When you define a virtual machine scale set with an Azure template, the Microsoft.Compute/virtualMachineScaleSets resource provider can include a section on extensions. The extensionsProfile details what is applied to the VM instances in a scale set. To use the Custom Script Extension, you specify a publisher of Microsoft.Azure.Extensions and a type of CustomScript.

The question is confusing. It asks "You plan to automate the deployment of a virtual machine scale set". But then why would I want to create the Scale Set manually in the portal (answer C)? I would provide an inline script as described here https://docs.microsoft.com/en-us/azure/azure-resource-manager/templates/template-tutorial-deploy-vm-extensions#edit-the-template

C & E are correct answers.

c and e is correct. As per the new requirement, you will need a new scale set & in the template the new script will go under extension profile.
