A DevOps team is planning to deploy a web application to an Azure Web App service. In order to provide new release, they decide to use deployment slots in the Azure Web App service. They have an App Service plan in place that is based on the Standard tier. 
They have to create a script to perform the following steps. Create a web app and attach it to the App service plan.
Create a deployment slot.
Initiate a swap of the deployment slots.
You have to complete the below script for this requirement. 

Which of the following would go into Slot3?

Answer options:

A.New-AzWebAppSlot
B.New-AzResourceGroup
C.New-AzWebApp
D.Invoke-AzResourceAction

Answer – D 
Here we need to use the Invoke-AzResourceAction cmdlet to perform the swap process. 
An example of this is also given in the Microsoft documentation. 

Since this is clearly given in the Microsoft documentation, all other options are incorrect.
