In your Automatic Storage Management （ASM） instance， one of the nonempty disk groups， DGROUP1， is no longer required and you want this disk group to be removed. You execute the following command to achieve this objective：
DROP DISKGROUP dgroup1 EXCLUDING CONTENTS；
What would be the result of this command？（）
A. This command would result in an error because the disk group is not empty.
B. The command would distribute the contents of the specified disk group among all other disk groups and then drop the specified disk group.
C. The command would result in the contents being moved to the parent disk group and dropping of the disk group.
D. The command would result in the disk group being marked as INVALID because it cannot be dropped.
E. The command would drop the disk group， ignoring the EXCLUDING CONTENTS option.

LOG_ARCHIVE_DEST = +dgroupA
LOG_ARCHIVE_FORMAT = "$ORACLE_SID_%s_%t.%t"
DB_CREATE_FILE_DEST = +dgroupA

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.

One of the tablespaces is readonly in your database. The loss of all control files forced you to recreate the control file. Which operation do you need to perform after recreating the control file and opening the database？（）
Your database operates in ARCHIVELOG mode and all the tablespaces are online. Due to a user error， you decided to perform an incomplete recovery. Which two tasks would you be required to perform in the recovery process？ （）
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？（）
View the Exhibit. One of the important tables in the USERS tablespace was dropped and purged from the recycle bin at 9：00 a.m. You noticed this at 11：00 a.m. and you want to perform an incomplete recovery to recover the table. Which statement is true？（）
You lost the PRODSTD tablespace， which was read/write. The tablespace was readonly when the last backup was performed. How would you recover the tablespace？（）
You enabled the flashback logging feature， but you have not specified the location of the flash recovery area. Which location would be used as the default location for the flash recovery area？（）
You configured the flash recovery area in the database. Which two files would you expect to find in the flash recovery area？ （）
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？（）
