+Create a DDoS Protection plan with [New-AzDdosProtectionPlan](/powershell/module/az.network/new-azddosprotectionplan) to associate with the virtual network. This example creates a DDoS Protection plan named **myDDoSPlan** in the **EastUS** location:

 ## Create a virtual network and bastion host
 
 A virtual network and subnet is required for to host the private IP address for the private endpoint. You'll create a bastion host to connect securely to the virtual machine to test the private endpoint. You'll create the virtual machine in a later section.
