Which of the following could cause data to be unavailable?

  • A.Data becoming lost or inaccurate
  • B.The database server
  • C.Planned database maintenance activities
  • D.All of the above.

Answer: D

Correct answer: All of the above.

Data may be unavailable for any of the three reasons: it may be lost or inaccurate, the server may be down, or the database may be off-line for planned maintenance. Availability is a matter of the whole system, not of the data alone, which is why maintenance windows are themselves an availability cost.
