 You'll see some REST requests and responses in the console as the SDK makes its underlying calls to the Azure REST API to configure the virtual machine and its resources. When the program finishes, verify the virtual machine in your subscription with the Azure CLI 2.0:
 
 ```azurecli
-az vm list --resource-group sampleResourceGroup --query [].name
+az vm list --resource-group sampleResourceGroup
 ```
 
-```json

+az vm delete --resourceGroup sampleResourceGroup --name testLinuxVM
