You have to create a multi-stage docker image for an ASP.Net core 2.2 application. Below is the incomplete Dockerfile. The Dockerfile is located in your project directory. 

Which of the following would go into Slot2?

Answer options:

A.mcr.microsoft.com/dotnet/core/aspnet:2.2
B.mcr.microsoft.com/dotnet/core/sdk:2.2
C.ENTRYPOINT
D.RUN
E.FROM

Answer – D 
The next part is to use the “RUN” command to publish a release of the application. 
An example of this is given in the Docker documentation. 

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