Challenge - 5 Problems

💻 Command Output

What is the output of this Azure PowerShell command?

You run the following command to list all resource groups in your Azure subscription:

Get-AzResourceGroup | Select-Object -First 1 -Property ResourceGroupName

What will this command output?

PowerShell

Get-AzResourceGroup | Select-Object -First 1 -Property ResourceGroupName

A An error saying 'Get-AzResourceGroup' is not recognized

B A list of all resource group names in plain text

C An object showing the name of the first resource group, e.g., @{ResourceGroupName=MyResourceGroup}

D An empty output with no resource groups listed

💡 Hint

Think about what Select-Object does when you specify a property and limit the output to the first item.

The command gets all resource groups, then selects only the first one and shows its ResourceGroupName property inside an object format.

📝 Syntax

Which option correctly logs in to Azure using PowerShell?

You want to log in to your Azure account using PowerShell. Which command syntax is correct?

A Connect-AzAccount

B Login-AzAccount

C Connect-AzureRmAccount

D Login-AzureAccount

💡 Hint

The current Azure PowerShell module uses 'Az' prefix commands.

The correct command to log in is Connect-AzAccount. The others are either deprecated or invalid.

Why does this script fail to create a resource group?

You run this script to create a resource group but get an error:

New-AzResourceGroup -Name $rgName -Location $location

Variables $rgName and $location are set as:
$rgName = 'TestGroup'
$location = 'eastus'

What is the most likely cause of the error?

PowerShell

$rgName = 'TestGroup'
$location = 'eastus'
New-AzResourceGroup -Name $rgName -Location $location

A The New-AzResourceGroup cmdlet does not accept the -Location parameter

B The location 'eastus' is invalid and misspelled

C The variable $rgName is empty

D You are not logged in to Azure before running the command

💡 Hint

Check if you have an active Azure session before creating resources.

If you are not logged in with Connect-AzAccount, the command will fail because it cannot authenticate.

How to automate stopping all running Azure VMs in a subscription?

You want to write a PowerShell script that stops all running virtual machines in your Azure subscription. Which script snippet correctly does this?

A Get-AzVM -Status | Where-Object {$_.PowerState -eq 'VM running'} | Stop-AzVM -Force

B Get-AzVM | Where-Object {$_.PowerState -eq 'VM running'} | Stop-AzVM -Force

C Get-AzVM | Stop-AzVM -Force

D Get-AzVM -Status | Stop-AzVM -Force

💡 Hint

You need to get the VM status to filter running VMs before stopping them.

Get-AzVM -Status retrieves VM status including PowerState. Filtering on PowerState 'VM running' ensures only running VMs are stopped.

What is the effect of running this Azure PowerShell pipeline?

Consider this command:

Get-AzResource -ResourceType 'Microsoft.Compute/virtualMachines' | Where-Object {$_.Location -eq 'westus'} | Remove-AzResource -Force

What does this command do?

PowerShell

Get-AzResource -ResourceType 'Microsoft.Compute/virtualMachines' | Where-Object {$_.Location -eq 'westus'} | Remove-AzResource -Force

A Lists all virtual machines in West US but does not delete them

B Deletes all virtual machines located in the West US region without asking for confirmation

C Deletes all resources in the subscription regardless of type or location

D Throws an error because Remove-AzResource cannot be piped input

💡 Hint

Look at the pipeline: it filters VMs by location, then deletes them with -Force to skip confirmation.

The command gets all VMs, filters those in 'westus', then deletes them forcefully without confirmation prompts.
