Agreed. I'm not sure why 3 people's votes came out at a low "3". I gave it a 5.

The unexpected good thing about it is that the number of incorrect answers actually show a really bad thing... a lot of people don't know backups deep enough.

To be honest, I think this would make a great pre-interview question.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Thanks for the instructive question - even though I got it wrong (mistakenly thought choice 4 was true).

Am I the only one who struggled with item 1 thinking "What if the previous log backup was done with COPY_ONLY?"

COPY_ONLY will not break the backup chain. They can also not be used as a base for further differential backups

True, but a COPY_ONLY log backup will not truncate the log, which is what I was getting at.
