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? ()
A.the trace file
B.the alert log file
C.an RMAN session log file
D.the server parameter file
E.the formatted name of a control file autobackup

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?()
A.by using the trace file
B.by using the alert log file
C.by using the database ID
D.by using the server parameter file
E.by using the V$CONTROLFILE view
F.by using the autobackup format configuration setting
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
B.add new tempfiles to the temporary tablespaces after recovery
C.perform a media recovery and open the database with the RESETLOGS option
D.perform a media recovery and bring the database to NOARCHIVELOG mode
In your database, all the tablespaces are locally managed. You started Recovery Manager (RMAN) using recovery catalog. The following commands are used in the process of recovering the database by using the backup control file:
In what sequence would you use this process to perform the recovery?()
A.7, 2, 3, 1, 4, 6, 5
B.7, 1, 3, 2, 6, 5, 4
C.2, 1, 7, 6, 3, 5, 4
D.2, 7, 3, 5, 1, 6, 4
The loss of the control file forced you to recreate the control file. After recreating it and opening the database, you find that some of the data files are named as MISSINGnnnnn, where nnnnn is a fivedigit number starting with 0.
What could be the possible reason?()
A.These are the data files that are corrupted.
B.There is no SYSAUX tablespace in your database
C.There is a readonly tablespace in your database.
D.These are the data files that cannot be recovered.
A.drop the readonly tablespace and recreate the tablespace after recovery
B.take data files from the readonly tablespace offline before performing a recovery
C.perform a recovery; status of the tablespace in control file will be changed automatically
D.recovery using backup control file is not possible, so restore all the files from the last full database backup, and then open the database
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?()
A.drop and recreate the readonly tablespaces
B.rename the readonly data files to their correct file names
C.change the tablespace status from read/write to readonly
D.recreate the readonly tablespace because it is automatically removed
A.restore the tablespace from the backup; there is no need to apply the redo information
B.restore the full database to recover the data up to the point when you performed the backup
C.restore the tablespace from the backup, and then perform a recovery using the backup control file
D.restore the tablespace from the backup, and then recover the tablespace; all the redo information from the point when the tablespace was made read/write is applied
A.ONLINE
B.REVERSE
C.PARALLEL
D.COMPRESS
E.NOLOGGING
F.COMPUTE STATISTICS
You lost the index tablespace in your database. You decided to recreate the index tablespace and the indexes in the tablespace.
What methods can you use to recreate the indexes?()
A.Data Pump
B.SQL scripts
C.SQL*Loader
D.Flashback database
E.Recovery Manager (RMAN) script
A.The index tablespace contains bitmap indexes.
B.The index tablespace contains more than one data file.
C.The index tablespace supports only complete recovery.
D.The index tablespace is not a dictionarymanaged tablespace.
E.There is a dependency relationship between a table and its indexes.

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?()
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?()
Your database operates in ARCHIVELOG mode. The redo log files are not multiplexed and one of the online redo logs is missing. The missing redo log sequence, 230, is not archived, and it contained information from 10:35 a.m. onwards. The current time is 11:00 a.m. Because of a disk crash, you executed the following command to perform an incomplete recovery: RMAN> RUN { 2> SET UNTIL SEQUENCE 230 THREAD 1; 3> ALTER DATABASE MOUNT; 4> RESTORE DATABASE; 5> RECOVER DATABASE; 6> ALTER DATABASE OPEN RESETLOGS;7> }; With reference to this scenario, which statement is true?()
