You have to deploy Internet Information Services to an Azure virtual machine that runs Windows Server 2019. You have to carry out the deployment using the Desired State Configuration. 
You have to complete the below script for this requirement. 

Which of the following would go into Slot 2?

Answer options:

A.Configuration
B.DependsOn
C.File
D.IncludeAllSubFeature
E.WindowsFeature

Answer – E 
Here we need to specify the WindowsFeature option. 
An example of the IIS configuration is shown below. 
<pre>configuration test
{
node "localhost"
{
WindowsFeature IIS
{
Ensure = "Present"
Name = "Web-Server"
}
}
}
</pre>
The other options are incorrect because we have to use the WindowsFeature keyword.
