There are many roles and features available for Nano Server, along with the Windows PowerShell options that will install the packages for them. Some packages are installed directly with their own Windows PowerShell switches (such as -Compute); others you install by passing package names to the -Packages parameter.
Which option would you use to configure the Nano Server image to be a dynamically expanding VHD or VHDX?
That was the correct answer, well done! 
Sorry, that was the wrong answer
