286.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.

287.Evaluate the following command:
SQL> CREATE TABLE design_data
(

B. ASM_DISKSTRING
C. ASM_DISKGROUPS
D. INSTANCE_TYPE

289.You are managing the APPPROD database as a DBA which is not using the Oracle-managed files.
You plan to duplicate this database in the same system with the name DUPDB.You want to create the same directory structure for duplicate database files as of the target database.
You executed the following RMAN commands:
RMAN> CONNECT TARGET sys/sys@APPPROD
RMAN> CONNECT AUXILIARY sys/sys@DUPDB
RMAN> DUPLICATE TARGET DATABASE TO dupdb FROM ACTIVE DATABASE PASSWORD FILE SPILE NOFILENAMECHECK;
What are the implications of this command?
A. It creates database files for the duplicate database under the Oracle base with a different directory for the duplicate database.
B. It overwrites data files of the target database because a different location for data files is not mentioned for the duplicate database.
C. It creates database files for the duplicate database under the same Oracle home as that of the target database with the same directory structure.
