Exam AZ-104 topic 1 question 5 discussion

The az vm create command. you need to create an Ubuntu Linux VM using a cloud-init script for configuration. For example, az vm create -g MyResourceGroup -n MyVm --image debian --custom-data

In my opinion the correct option is D) "The az vm create command". "New-AzureRmVm" is the legacy way to create Vms using Powershell (https://docs.microsoft.com/en-us/powershell/module/azurerm.compute/new-azurermvm?view=azurermps-6.13.0). "New-AzVM" Is the current way to create VMs using Powershell (https://docs.microsoft.com/en-us/powershell/module/az.compute/new-azvm?view=azps-8.3.0). Using Powershell cmdlets I think that it is not currently supported to create a VM passing custom data, like a cloud-init file to accomplish the requested trust for a Custom CA. "Create-AzVM" Does not seem to exist. Using AZ cli or ARM Templates we can accomplish this: https://docs.microsoft.com/en-us/azure/virtual-machines/custom-data

The New-AzVM cmdlet can be used to create virtual machines in Azure, but it might not be as straightforward for adding a trusted root certification authority (CA) during the VM creation process. This task typically requires custom scripts or cloud-init configurations, which are more easily implemented using the az vm create command. The az vm create command allows you to specify custom data and scripts that can run during the VM provisioning, making it more suitable for complex custom deployments like adding a trusted root CA.

This is from AI , The correct answer is: B. The New-AzVM cmdlet. 🔍 Here's the breakdown: You're deploying an Ubuntu Server VM in Azure with a custom configuration (like adding a trusted root CA). That points to using PowerShell (not CLI), and more importantly, the current PowerShell module. 🧠 Why not the others? A. New-AzureRmVm ❌ Outdated. The AzureRM module is deprecated and replaced by Az. Avoid using this unless you want to time-travel back to 2018. C. Create-AzVM ❌ Doesn’t exist. Not a real cmdlet. You might be thinking of New-AzVM, which is the valid one. D. az vm create ✅ Technically valid, but that’s Azure CLI, not PowerShell. If you're going for scripting in Bash or Cloud Shell, sure. But you mentioned custom deployment—PowerShell gives you more control for that, especially for complex provisioning scripts.

You can configure the existing usage of model from "per authentication" to per enable user" vi the Azure portal

This option enable you to run scripts during employment to configure the VM including the adding trusted CAs

The az vm create command. you need to create an Ubuntu Linux VM using a cloud-init script for configuration.

Create the virtual machine To create a VM in this resource group, use the vm create command.

Others option don't have may options like use sshkey or imprt certificate from vault.

In my opinion the correct option is D) "The az vm create command".

This command is part of the Azure CLI, and it allows for more extensive customization options, including the ability to specify custom scripts for post-deployment configuration, such as adding a trusted root certification authority (CA).

Razón por la cual no se eligen las otras opciones: A. New-AzureRmVm: Este cmdlet pertenece al módulo AzureRM, que está obsoleto y reemplazado por Az. B. New-AzVM: Aunque es parte del módulo más reciente Az, es un cmdlet de PowerShell y no es la opción más flexible para configuraciones avanzadas como la personalización de certificados en Linux. C. Create-AzVM: No existe un cmdlet con este nombre en Azure PowerShell.

If using Azure CLI, the answer is D. If using Azure PowerShell, the answer would be B, but since the question does not specify PowerShell, D is the most fitting choice.

correct Answer is B New-AzVm ` -ResourceGroupName 'myResourceGroup' ` -Name 'myVM' ` -Location 'East US' ` -image Debian11 ` -size Standard_B2s ` -PublicIpAddressName myPubIP ` -OpenPorts 80 ` -GenerateSshKey ` -SshKeyName mySSHKey https://learn.microsoft.com/en-us/azure/virtual-machines/linux/quick-create-powershell

yep D!

To implement a custom deployment that includes adding a particular trusted root certification authority (CA) when creating an Ubuntu Server virtual machine in Azure, you should use the az vm create command (Option D). During the VM creation process, the az vm create command allows you to specify custom scripts and configurations, such as adding a trusted root CA. This flexibility makes it suitable for custom deployments.

Defenitly D
