Discussion
Mirrored databases are almost always provided in high-availability systems.
Answer: A
Correct answer: True
A high-availability system cannot afford the time a restore from backup would take, so it keeps a complete second copy written in step with the first. If one fails the other carries the service immediately. Mirroring guards against media and site failure; it does not guard against a logical error, which is faithfully mirrored too.
