第4题：

You observe that the senior database administrator always uses the following command when connecting to Recovery Manager （RMAN）， and then starts executing commands to backup the database files：  $ rman target /  What would be the effect of this command？（）

• A、RMAN would use the current operating system location to place the backup.
• B、RMAN would use the control file of the target database to maintain the backup.
• C、RMAN would use the recovery catalog of the target database to maintain the backup.
• D、RMAN would use the control file of the target database to maintain the backup metadata. 
• E、RMAN would use the recovery catalog of the target database to maintain the backup metadata.

第5题：

You executed the following command in Recovery Manager （RMAN）：  RMAN> RESTORE CONTROLFILE；  Which operation must you perform before this command is executed？（） 

• A、back up the control file to trace
• B、bring database to the MOUNT state
• C、open a connection to the RMAN recovery catalog， which contains the RMAN metadata for the target database
• D、set the database ID （DBID）， but only if the DB_NAME parameter associated with the target database is unique in the recovery catalog

第6题：

Which statement is true regarding RMAN components？（）

• A、Each target database requires its own recover catalog. 
• B、RMAN scripts can be stored in the recovery catalog or the target control file. 
• C、A channel is a stream of data to a device type and corresponds to one server session. 
• D、The RMAN executable interprets sever session commands and establishes connections to the target database.

第7题：

You are using a recovery catalog to maintain Recovery Manager （RMAN） backup information for your production database. You have registered your production database and are performing regular backups. Because of a new requirement you have added a few new tablespaces to your production database and you want them to be included in backups.  Identify two options for completing this task.（）

• A、 Reregistering the target database in recovery catalog
• B、 Transporting the new tablespaces to the recovery catalog database
• C、 Syncronizing the recovery catalog with the target database control file
• D、 Performing a fresh backup of the target database to include the new data files in the catalog database

第9题：

It is a holiday and no transactions are being performed on the database. You took a consistent backup of your database without using Recovery Manager （RMAN）. How would you make use of this consistent backup in RMAN？（）

• A、cannot be used in RMAN
• B、by starting up the database again
• C、by using the CATALOG command of RMAN
• D、by using the RECOVER CATALOG command in RMAN
• E、by re-creating the target control file to rebuild the RMAN repository

第10题：

In your database， all the tablespaces are locally managed. You started Recovery Manager （RMAN） using recovery catalog and restored the control file by using the following command： RMAN> RESTORE CONTROLFILE;  Which two operations do you need to perform after restoring the control file from backup？（）

• A、shut down and restart the instance
