C. The backup contains only data files and archived redo log files
D. The backup contains data files, the server parameter file and the control file even if the control file auto backup is disabled
[单项选择] You have enabled backup optimization in RMAN. You issue the following RMAN command to configure a redundancy-based retention policy: CONFIGURE RETENTION POLICY TO REDUNDANCY 3; Which statement is true?（）

B. Backup optimization is performed, but RMAN considers the redundancy-based retention policy when it determines which datafiles should be backed up
C. Backup optimization is permanently disabled
D. Backup optimization is temporarily disabled because a redundancy-based retention policy is specified

B. The backup as copy can only be taken to tape
C. Backup can be performed only when the instance is shutdown
D. Backup will constitute all used and unused blocks in the database

[单项选择] In Recovery Manager (RMAN), you are taking image copies of the data files of your production database and rolling them forward at regular intervals. You attempt to restart your database. After a regular maintenance task, you realize that one of the data files that belongs to the USERS tablespace is damaged and you need to recover the data file by using the image copy. Because a media failure caused the data file to be damaged, you want to place the data file in a different location while restoring the file. Which option must you consider for this task?（）
A. using only the RMAN SWITCH command to set the new location for the data file
B. placing the database in the MOUNT state for the restore and recovery operations.
C. using an RMAN RUN block with the SET NEWNAME and then the SWITCH command.
D. configuring two channels: one for the restore operation and the other for the recovery operation
[单项选择] You executed the following command: RMAN> RECOVER COPY OF DATAFILE '/u01/app/oracle/oradata/orcl/users01.dbf'; Which statement regarding the above command is correct?（）
A. The '/u01/app/oracle/oradata/orcl/users01.dbf' data file is recovered from the image copy
B. The '/u01/app/oracle/oradata/orcl/users01.dbf' data file is recovered from the last incremental backup
C. Image copies of the '/u01/app/oracle/oradata/orcl/users01.dbf' data file are updated with all changes up to incremental backup SCN. '/ u01/app/oracle/oradata/orcl/users01.dbf
D. Image copies of the '/u01/app/oracle/oradata/orcl/users01.dbf' data file are recovered using the above command if data file recovery fails

B. It will display a list of files that need backup after five days
C. It will display a list of files that were backed up in the last five days
D. It will display a list of files that have not been backed up in the last five days
E. It will apply the current retention policy to determine the files that need to be backed up
[单项选择] You executed the following commands in an RMAN session for your database instance that has failures: RMAN> LIST FAILURE; After some time, you executed the following command in the same session: RMAN> ADVISE FAILURE; But there are new failures recorded in the Automatic Diagnostic Repository (ADR) after the execution of the last LIST FAILURE command. Which statement is true for the above ADVISE FAILURE command in this scenario?（）
A. It produces a warning for new failures before advising for CRITICAL and HIGH failures.
B. It ignores new failures and considers the failures listed in the last LIST FAILURE command only.
C. It produces an error with recommendation to run the LIST FAILURE command before the ADVISE FAILURE command.
D. It produces advice only for new failures and the failures listed in the last LIST FAILURE command are ignored.
