If a database is restored using before-image dumps, where
should the process be restarted following an interruption?

A. Before the last transaction

B. After the last transaction

C. The first transaction after the latest checkpoint

Question Posted / guest

Answer Posted / guest

Answer: A

If before images are used, the last transaction in the dump
will not have updated the database prior to the dump being
taken. The last transaction will not have updated the
database and must be reprocessed. Program checkpoints are
irrelevant in this situation.
