DRAG DROP
You administer a Microsoft SQL Server 2012 server.
You need to install the Power View components on a stand-alone server.
Which three 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: 
3-2-5
3 – 2 – 5 indeed.
Also checked the comments on previous version, most of them claim 3-2-5 too.
Yep, I don’t think you can instal reposting server first. and then, the engine.
You can install the Report Server first but you can’t configure it until the database engine hosting the SSRS databases is up.
i would say: 2 – 5 …
engine is already installed (“you administer a…”)
and powerVIEW is asked…
