I first thought a "clone" was a 1-to-1 copy of all the data, so I chose the third answer...

Well, if you had a big database, having to copy it as a whole didn't sound so efficient.

Even if you took a snapshot it wouldn't be so easy if you have much activity... and besides all I'm not sure I could create new SPs and change things around without touching the original db...

Anyway I realized that "cloning" has a different meaning here, so my answer was clearly wrong.. at least I learned something new (also) today 😀

Have a nice day!
