You want an ASM instance to manage the files of your database. To achieve this objective， you specify the following parameters in the parameter file of the database： INSTANCE_TYPE = RDBMS DB_NAME = PROD
LARGE_POOL_SIZE = 8MB DB_BLOCK_SIZE = 4K
LOG_ARCHIVE_DEST = +dgroupA
LOG_ARCHIVE_FORMAT = "$ORACLE_SID_%s_%t.%t"
DB_CREATE_FILE_DEST = +dgroupA
COMPATIBLE = 10.1.0.2.0
CONTROL_FILES = +dgroupA
Which parameter would be ignored while starting up the instance for the database PROD？（）
A. LARGE_POOL_SIZE
B. DB_CREATE_FILE_DEST
C. LOG_ARCHIVE_DEST
D. CONTROL_FILES
E. LOG_ARCHIVE_FORMAT
F. DB_BLOCK_SIZE
You have created a resource plan， PROD_DB_PLAN， that uses the RATIO policy. The following consumer groups and their respective plan directives have been assigned to this resource plan： Consumer group HIGH_CG with CPU_P1 as 10.
Consumer group MEDIUM_CG with CPU_P1 as 5.
Consumer group LOW_CG with CPU_P1 as 2.
Consumer group OTHER_GROUPS with CPU_P1 as 1.
Which statement is correct in this scenario？（）
A. The CPU allocation would be equal between the HIGH_CG and MEDIUM_CG consumer groups if there are no sessions existing for the LOW_CG and OTHER_GROUPS consumer groups.
B. The members of the HIGH_CG consumer group would get 10% of the CPU.
C. The plan PROD_DB_PLAN can have subplans.
D. The CPU allocation for the consumer groups would be based on the ratio defined for the CPU_P1.
A. If the FORMAT option to the RMAN BACKUP command is specified， then RMAN creates backup pieces and image copies in the flash recovery area with names in the Oracle Managed Files （OMF） format.
B. If any local destinations for LOG_ARCHIVE_DEST_n are set， then archived redo logs are stored in these destinations as well as in the flash recovery area.
C. If the flash recovery area location is configured using the DB_RECOVERY_FILE_DEST initialization parameter， then the RMAN backup of Oracle managed datafiles （OMF） only will go to the flash recovery area by default.
D. If no other destination is configured for recovery files， then RMAN places the control file autobackups in the flash recovery area by default.
A. backup pieces
B. copies of all the parameter files
C. trace file generated using BACKUP CONTROLFILE TO TRACE
D. control file autobackups
A. The database writer writes to a trace file， indicating that the temporary file is not found.
B. The database prompts for a database recovery.
C. The database opens normally.
D. The database gets mounted and throws an error indicating that the temporary file requires recovery.
A. The database must be started in the MOUNT EXCLUSIVE state.
B. The database must have multiplexed control files.
C. The database must be opened by using a text-based parameter file instead of a server parameter file （SPFILE）.
D. The database must be in ARCHIVELOG mode.
E. The database must be in the NOMOUNT state.
F. The database must be opened in RESTRICTED mode.
A. The Oracle database will not perform block checking for any of the data blocks.
B. The Oracle database will perform block checking for the default permanent tablespace only.
C. The Oracle database will perform block checking for the data blocks in all user tablespaces.
D. The Oracle database will perform block checking for the data blocks in the SYSTEM tablespace only.
E. The Oracle database will perform block checking for the data blocks in the SYSTEM and SYSAUX tablespaces.
A. log buffer
B. Java pool
C. Large pool
D. Fixed SGA
E. Shared pool
F. Streams pool
G. Keep buffer cache
H. Database buffer cache
A. Enable flashback logging.
B. Start the database in the ARCHIVELOG mode.
C. Issue the ALTER DATABASE FLASHBACK ON； command.
D. Set the FAST_START_MTTR_TARGET initialization parameter.
A. DBMS_RLS.STATIC
B. DBMS_RLS.DYNAMIC

You used the following command in Recovery Manager （RMAN） as part of the recovery process： RESTORE CONTROLFILE FROM AUTOBACKUP; How does RMAN find the control file autobackup？（）
You have only two redo log groups and these groups get overwritten several times in a day. Your database operates in NOARCHIVELOG mode and usermanaged consistent backups are performed every Sunday night. On Thursday morning， you find that an important table has been dropped and purged. With reference to this scenario， up to what point in time can the data be recovered？（）
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？（）
Your database operates in ARCHIVELOG mode and usermanaged consistent backups are performed every Sunday night. On Tuesday， at 9：00 a.m. the current log sequence number was 369. Also， on Tuesday you lost the data file belonging to the SYSTEM tablespace and an archivelog file （sequence number 356） that contained redo entries between 8：00 a.m. and 8：30 a.m. With reference to this scenario， what would you do to recover the database？（）
Your database operates in ARCHIVELOG mode. Usermanaged consistent backups are performed every Sunday night. On Tuesday， client A drops a table at 8：00 a.m. as follows： SQL> DROP TABLE cust_ord PURGE; Table dropped. Client B executes a query at 9：00 a.m. on the same table as follows： SQL> SELECT * FROM cust_ord;SELECT * FROM cust_ord* ERROR at line 1： ORA00942： table or view does not exist Client B needs the dropped table and reports the problem to you. With reference to this scenario， which action should you take？（）
You are connected to Recovery Manager （RMAN） without a recovery catalog. There is no copy of the control file available. You want to restore the control file from an autobackup. To retrieve the autobackup，you need the database ID （DBID）. In which two sources would you find the DBID？ （）
You decided to change the location of the flash recovery area. You executed the following command： Which statement is true？（）
The current time is 12：00 noon. You want to recover the USERS tablespace from a failure that occurred at 11：50 a.m. You discover that the only member of an unarchived redo log group containing information from 11：40 a.m. onwards is corrupt. With reference to this scenario， if you are not using Recovery Manager （RMAN）， which recovery method would you use？（）
You executed the following query in your database： FROM V$FLASHBACK_DATABASE_LOG; What would you determine from the output？（）
You disabled the Flashback Database feature by using the following command： SQL> ALTER DATABASE FLASHBACK OFF; What would be the effect of this command on the existing flashback logs？（）
