The Oracle Database 11g database is running in the ARCHIVELOG mode. The archived redo log files are stored on three locations. The Flash Recovery Area is one of the locations. The details are given below:
LOG_ARCHIVE_DEST_1 = ’LOCATION = /disk1/archive’ LOG_ARCHIVE_DEST_2 = ’SERVICE = stdb1’ DB_RECOVERY_FILE_DEST = ’/u01/oradata’
Examine the following RMAN command issued to set the deletion policy for archived log files:
RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO BACKED UP 2 TIMES TO sbt;
Which statement is true regarding what this command accomplishes?()
A. All archived redo log files backed up at least twice to tape are deleted.
B. All archived redo log files backed up at least once to tape are eligible for deletion.
C. All archived redo log files backed up at least twice to tape are deleted from the flash recovery area.
D. All archived redo log files in local archiving destinations and the flash recovery area backed up at least twice to tape are eligible for deletion.

Consider the following scenario for your database:
- Backup optimization is enabled in RMAN.
- The recovery window is set to 7 days in RMAN.
- The most recent backup to disk for the TOOLS tablespace was taken on November 3, 2007.
- The TOOLS tablespace is read-only since November 4, 2007.
On November 23, 2007, you issue the RMAN command to back up the database to disk.
Which statement is true regarding the backup of the TOOLS tablespace?()
A. The RMAN backup fails because the TOOLS tablespace is read-only
B. The RMAN skips the backup of the tablespace because backup optimization is enabled
C. The RMAN makes backup because optimization can be enabled only for backups to disk
D. The RMAN makes the backup because no backup of the tablespace exists within the seven day window
A. A base catalog exists
B. The recovery catalog is empty
C. The base recovery catalog must be dropped
D. A target database is registered in the recovery catalog
Evaluate the following SQL statement used to create the PRODUCTS table:

(150000), PARTITION p3 VALUES LESS THAN (MAXVALUE))
COMPRESS FOR ALL OPERATIONS;
Which statement is true regarding this command?()
A. It executes successfully but partition pruning cannot happen for this partition key.
B. It produces an error because the TOTAL_VALUE column cannot be used as a partition key.
C. It produces an error because compression cannot be used for the TOTAL_VALUE partition key.
D. It executes successfully but the values in the TOTAL_VALUE column would not be physically stored in the partitions.

Tape streaming is not happening while performing RMAN tape backup.

In Recovery Manager (RMAN), you are taking image copies of the datafiles of your production database and rolling them forward as regular intervals. You attempt to restart your database instance after a regular maintenance task, you realize that one of the data files that belongs to the USERS tablespace is damaged and you need to recover the datafile by using the image copy. You could perform the following steps to accomplish this: 1) Mount the database 2) Take the data file offline 3) Bring the data file online 4) Use the RMAN SWITCH TO command to switch the image copy 5) Apply the archived redo logs 6) Open the database 7) Use the RMAN RESTORE TO command to switch to the image copy Which two options illustrate the correct sequence of steps that you could follow?()
