A sounds like the most logical answer to me. Keeping the data mirrored in the other failure group until the first one is back online makes sense.

Haha, D made me chuckle. Transactions failing? That's just a typical day in the life of a DBA, isn't it?

Hmm, I'm not sure about C. Does that mean new data isn't mirrored, but changes are tracked? Seems like a strange behavior.

I think B is the correct answer. If one failure group goes offline, the redundancy is indeed lowered until it's restored and the disk group is resynchronized.

I agree with Adell. The redundancy is definitely lowered until FG1 is restored.
