A DevOps team needs to deploy an Azure resource manager template using PowerShell. You have to complete the below PowerShell script for this requirement. 

Which of the following would go into Slot 1?

Answer options:

A.New-AzARMdeploy
B.New-AzResourceGroupDeployment
C.New-Azdeploy
D.Set-AzResourceGroupDeployment

Answer – B 
We have to use the New-AzResourceGroupDeployment cmdlet to specify a new ARM template deployment. 
This is also given as an example in the Microsoft documentation. 

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