Question

The MySQL server host crashes at 10:00 in the morning, and is brought back online at 10:30. In order to ensure that all data are consistent, a copy is first made of the table, tablespace and log files currently on the server host, and these files are then restored from a backup made at 03:00 the same morning. What should be done in order to bring the database to the state it was at just before the server host crashed?

Options

  • AThe mysql_restore utility should be used to update the server to its last known state.
  • BThe binary logs recorded after the backup at 03:00 should be re-applied to make the database file
  • CThe procedure described is wrong; instead, the mysqlcheck utility should be used and only if that
  • DOnce the backup files from 03:00 have been restored, there is nothing more that can be done to
