　　You are using Recovery Manager (RMAN) with a recovery catalog to back up your production database.
The backups and the archived redo log files are copied to a tape drive on a daily basis. Because of media failure, you
lost your production database completely along with the recovery catalog database. You want to recover the target
database and make it functional.
　　You could consider performing the following steps to accomplish this task:
1) Restore an autobackup of the server parameter file.
2) Restore the control file.
3) Start the target database Instance.
4) Mount the database.
5) Restore the data files.
6) Open the database with the RESETLOGS option.
7) Recover the data files.
8) Set DBID for the target database
Which option illustrates the correct sequence that you must use?
A. 8, 1, 3, 2, 4, 5, 7, 6
B. 1, 8, 3, 4, 2, 5, 7, 6
C. 1, 3, 4, 2, 8, 5, 6, 7
D. 1, 3, 2, 4, 6, 5, 7, 8
　　Correct Answer: B
　　QUESTION 105
You configured the default backup device type as disk for RMAN backups. In your database, because of
business requirements, you have to take a simultaneous duplicate backup of the data files when the RMAN
BACKUP command is used.
What must you set using the RMAN CONFIGURE command to achieve this?
A. MAXSETSIZE TO 2;
B. DEVICE TYPE DISK PARALLELISM 2;
C. RETENTION POLICY TO REDUNDANCY 2;
D. DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 2;
Correct Answer: C
　　QUESTION 111
　　You have configured flash recovery area in your database and you set the following Initialization
parameters for your database instance:
LOG_ARCHIVE_DEST 1 = 'LOCATION=/disk1/arch MANDATORY'
LOG_ARCHIEVE_DEST 2 = 'LOCATION=/disk2/arch'
LOG_ARCHIVK_DEST_3 = 'LOCATION=/diSk3/arch
LOG_ARCH1VK_DEST_4 = 'LOCATION=/disk4/arch'
LOG_ARCHIVE_MIN-SUCCEED_DEST = 2
While the database instance is functional, you realized that the destination set by the
LOG_ARCHIVE_DEST_I
parameter Is not available for the archived redo log file to be created in. All redo log groups have been
used. What happens in an event of log switch?
A. The online redo log file Is not allowed to be overwritten.
B. The archived redo log files are written to the flash recovery area until the MANDATORY destination is
made available.
C. The database instance will crash because the archived redo log file cannot be created in a destination
set as MANDATORY.
D. The destination set by the LOG_ARCHIVE_DEST_1 parameter is ignored and the archived redo log
files are created in the next two available locations to guarantee archive log success.
Correct Answer: D
