I have to admit that I failed the question and I was surprised. When I saw the correct answer I couldn’t believe it. Every single option that was selected as correct was not correct. I joined the discussion and only then I’ve noticed that the question was about the options that are not correct. In short I found out that maybe I know something about partitioning, but apparently I’m a poor at understanding what I read:-)

The question is challenging and asks for more attention on details when reading, this is not one of my main strengths.

I read the documentation, was lucky to find here:

Did anyone used the SWITCH option in production?

Thanks,

It is used as part of the archiving of large tables in our data warehouse environment.
Using SWITCH has reduced the population time from approx 36 hours (750+ million records) to add approx 25 million records per month to less that 1 hour (99.9% of that time taken to populate the staging table from which the data is switched into the archive table, the actual switching operation takes on average 10 milliseconds)
