The computer shouldn't say "You are wrong". It should say, "You are incorrect".

The computer doesn't say anything. The question setter says "You are wrong" BigGrin

In my case, I didn't think carefully enough about the reasons:

tempdb can't have snapshots because it's rarely explicitly referenced and a read-only temporary area is pointless.

model is a template, so should be treated as read-only anyway (plus it's never referred to explicitly either).

master contains the description of the structure of all other databases (amongst other things), so a snapshot wouldn't work because it may not describe the structure correctly and hence would be unusable.

The other 3 are really just ordinary databases. Although msdb contains a lot of MS specific stuff such a scheduling info, it's really just an ordinary database.

I missed out on master Sad

(... Waiting for someone more knowledgeable to correct me ... )

I got it wrong, didn't know that creating a snapshot for msdb is not "prohibited" but I have to wonder - what would be the purpose of creating a snapshot for msdb?

I hate when I don't read the question correctly. I got my logic flipped when I didn't read "not" allowed.

I could see a snapshot on msdb for history purposes or even testing since it's got scheduling/history data.

"You are wrong" and "incorrect" mean the same thing. I see nothing wrong or incorrect with saying "you are wrong."

Cool

Darn good question.
Between the database setting of Allow_snapshot_isolation, all the Row versioning techniques / abilities, then throw in the MSDB for good measure. Now I think I know how much I did NOT know about snapshots - their advantages / disadvantages. backing up of a snapshot and on and on and on and on ad nausim.
Again a good question relatively simple, yet a great learning experience

If everything seems to be going well, you have obviously overlooked something.
