Doh!! Goes to show what you get when you click through something too quickly without checking your answers! (I checked 0 when I meant to check 1).

I was shocked to see only 49% getting this right (when I checked). Surely all DBAs should be all over this one.

Yeah, it was a "no-brainer" and evidently my brain didn't click the right one!!

My guess is that many made the mistake that I did - I selected the answer that ONLY protects against a single disk failure (i.e, RAID 1). I don't think in terms of multiple answer questions well...

Yeah, I can't really say too much as I've got some no-brainers wrong before too.

Actually, RAID 5 is the only RAID level that guarantees protection for at most one disk failure. RAID 1 and RAID 10, depending on how they are configured, can protect against more than one. There is no strict definition that says RAID 1 must only be a mirrored *pair*.
