From the Cloud Shell pane, run the following to create the first resource group that will be hosting the first virtual network and the pair of virtual machines:
$location = 'West US'
$rgName = 'My-RG01' 
New-AzResourceGroup -Name $rgName -Location $location

From the Cloud Shell pane, run the following to create the first virtual network and deploy a pair of virtual machines into it by using the template and parameter files you uploaded:
New-AzResourceGroupDeployment `
  -ResourceGroupName $rgName `
  -TemplateFile $HOME/az104-06-vms-template.json `
  -TemplateParameterFile $HOME/az104-06-vm-parameters.json `
  -AsJob
