You are managing an Oracle Database 11g database. You want to ensure the recovery of thedatabase to the point of failure. 
Which configuration will you do to accomplish the task（）

A.Inactive and current redo log files are required to accomplish recovery.
B.Online and archived redo log files are required to accomplish instance recovery.
C.All redo log entries after the last checkpoint are applied from redo log files to data files.
D.All redo log entries recorded in the current redo log file until the checkpoint position are applied to datafiles.

A.Disable automatic checkpoint tuning.
B.Check the size of the redo log file size and increase the size if it is small.
C.Set the FAST_START_MTTR_TARGET parameter as per the advice given by the MTTR Advisor. 
D.Decrease the number of redo log members if there are more than one redo log members available in each redo log group.

A.The checkpoint frequency decreases with the smaller redo log file size.
B.It ensures that all committed data is written to the data files during normal shutdown.
C.The frequent full checkpoint in a database can cause the overall degradation of the database performance.
D.It prompts the Checkpoint （CKPT） process to write data to the data files and redo information to the online redo log files.
