I have been following all the steps of the exercise but I am stuck at getting the IP address by $vm | Get-AzPublicIpAddress How may I get the IPAddress successfully?
The following is how I got the error, what did I do wrong? Thank you.

   PS /home/chung> New-AzVm -ResourceGroupName learn-e69c78ce-6aa1-4cab-bcd3-2e984a6ad302 -Name "testvm-eus-01" -Credential (Get-Credential) -Location "East US" -Image UbuntuLTS -OpenPorts 22

Hello @Chung Li Lam (MLCSU) ,
Thanks for reaching out to Microsoft QnA. Happy to answer your question.
As you mentioned, you want to fetch the public ip address of the VM. However, you will not be able to directly fetch it with the Get-AzPublicIpAddress cmdlet. Please run the below powershell script to do the same.

$vm = Get-AzVM -ResourceGroupName lab -Name win-lab  
$nic = $vm.NetworkProfile.NetworkInterfaces[0].Id.Split('/') | select -Last 1  
$publicIpName =  (Get-AzNetworkInterface -ResourceGroupName lab -Name $nic).IpConfigurations.PublicIpAddress.Id.Split('/') | select -Last 1  
$publicIpAddress = (Get-AzPublicIpAddress -ResourceGroupName lab -Name $publicIpName).IpAddress  
Write-Output $publicIpAddress  

I hope this helps.
