DRAG DROP
You administer 50 laptops that run Windows 7 Professional 32-bit. You want to install
Windows 8 Pro 64-bit on every laptop. Users will keep their own laptops. You need to ensure
that user application settings, Windows settings, and user files are maintained after Windows
8 Pro is installed. Which four actions should you perform in sequence? (To answer, move
the appropriate actions from the list of actions to the answer area and arrange them in the correct order.)
Answer: 
/hardlink: Enables the creation of a hard-link migration store at the specified location. The /nocompress option must be specified with the /hardlink option.
Switch the 2th box with the 3th box on the left without /nocompress i think?
Just to add to TimDuncan, Hard Link Migration is where you keep all user state data and completely remove the OS to clean install a new OS which is needed in this case as you cant upgrade a 32 bit machine to a 64 bit machine. Hope this helps people!!
Answer is correct. If is only a refresh scenario (users will keep their own laptops) /nocompress need to be specified, not avoided.
