Exam AZ-104 topic 4 question 9 discussion

Correct Answer: A and D 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. The Custom Script extension integrates with Azure Resource Manager templates, and can also be used with the Azure CLI, Azure PowerShell, Azure portal, or the REST API The following Custom Script Extension definition downloads a sample script from GitHub, installs the required packages, then writes the VM instance hostname to a basic HTML page.

A and D?

Correct Answer: A and D Explanation: Upload a configuration script: This allows you to create a script containing the commands needed to install the web server components on the newly provisioned VMs. Modify the extensionProfile section: Within your Azure Resource Manager template, the "extensionProfile" section is where you specify custom scripts to be executed during VM deployment, enabling the execution of your uploaded configuration script.

no better answer !

I think this topic was starting more helpful compared to questions in AD and storage account topic

To automate the deployment of a virtual machine scale set (VMSS) that uses the Windows Server 2016 Datacenter image and ensure that the web server components are installed during provisioning, you should perform the following actions: A. Upload a configuration script You can use a script (e.g., PowerShell or Bash) that installs the required web server components and upload it to an accessible location (like Azure Blob Storage). This script can be executed during the VM provisioning process. D. Modify the extensionProfile section of the Azure Resource Manager template You need to modify the extensionProfile section of your Azure Resource Manager (ARM) template to include an extension that runs the uploaded configuration script on each instance of the VM scale set. This is typically done using the Custom Script Extension for Windows, which executes the script after the VM is provisioned. Correct answers: A. Upload a configuration script D. Modify the extensionProfile section of the Azure Resource Manager template

A & D are correct

Correct Answers: A. Upload a configuration script D. Modify the extensionProfile section of the Azure Resource Manager template

A. Upload a configuration script: This script can be used to install the necessary web server components on the VM instances. You can create a script that installs these components and upload it to be used during the VMSS provisioning. D. Modify the extensionProfile section of the Azure Resource Manager template: The extensionProfile section allows you to specify VM extensions, which can be used to run scripts or other configuration tasks on the VM instances as they are provisioned. You would include a reference to the configuration script here. Correct Answers: A. Upload a configuration script D. Modify the extensionProfile section of the Azure Resource Manager template

Correct answers : A and D Even if we go by process of elimination, B and C are easily eliminated. E is tricky but since it involves manual work and not automation , that is also eliminated which leaves us with A and D as correct answers

as this is automating, you don't actually need the azure portal for the creation of the VMSS

To ensure that when the scale set virtual machines are provisioned, they have web server components installed, you need to: A. **Upload a configuration script**: This script will contain the necessary commands to install the web server components on a Windows Server 2016 Datacenter instance. D. **Modify the extensionProfile section of the Azure Resource Manager template**: The extensionProfile section in a Virtual Machine Scale Set ARM template allows you to specify extensions, which are

The keyword here is "Automate". You cannot automate with Portal deployments. Need to use ARM/BICEP/PS etc. So option with portal is eliminated. Out of others, Uploading a config script and then modifying extensionprofile part of ARM are correct steps.

Answers are; Upload a configuration script Modify the extensionProfile section of the Azure Resource Manager template 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.

To automate the deployment of a virtual machine scale set with web server components installed, you should perform the following two actions: A. Upload a configuration script: This script should include the necessary commands to install the web server components on the virtual machines in the scale set. You can upload this script to a storage account or any accessible location for the virtual machines to retrieve and execute during provisioning. D. Modify the extensionProfile section of the Azure Resource Manager template: In the Azure Resource Manager (ARM) template used for deploying the virtual machine scale set, you can include an extensionProfile section to specify the extensions to be installed on the virtual machines. You can add an extension that runs the previously uploaded configuration script to install the web server components. Therefore, the correct options are A and D.

Agree with mlantonis. Prepare a configuration script. https://learn.microsoft.com/en-us/azure/azure-resource-manager/templates/template-tutorial-deploy-vm-extensions - store the script in GitHub, so you can access it with a URI. In the ARM template, edit the extension profile section (a) fileURI (b) commandToExecute - so you can access the ARM template and execute the script to install the web server on the VM.
