RMAN>BACKUPINCREMENTALLEVEL0DATABASE; To enable block change tracking, after the incremental level 0 backup, you issue the command:

SQL>ALTERDATABASEENABLEBLOCKCHANGETRACKINGUSING FILE'/mydir/rman_change_track.f'; To perform an incremental level-1 cumulative backup, you issue the command:

RMAN>BACKUPINCREMENTALLEVEL1CUMULATIVEDATABASE; Which two statements are true in the preceding situation?
