A. The COMMIT order in the captured workload is preserved during replay.
B. The value 100 in the THINK_TIME_SCALE parameter attempts to make the replay client shorten the
think time between calls.
C. The value 100 in the CONNECT_TIME_SCALE parameter attempts to connect all sessions as captured.
D. The value 100 in the THINK_TIME_SCALE parameter attempts to match the captured user think time

You are managing an Oracle 11g database with ASM storage, for which the COMPATIBLE initialization parameter is set to 11.1.0.

Which two statements are true in this scenario for the features enabled for ASM? (Choose two.)
A. The ASM-preferred mirror read feature is enabled.
B. The ASM supports variable sizes for extents of 1, 8, and 64 allocation units.
C. The ASM disk is dropped immediately from a disk group when it becomes unavailable.
D. The RDBMS always reads the primary copy of a mirrored extent of the ASM disk group.
You set the following parameters in the parameter file and restarted the database:
Which two statements are true regarding these parameters after the database instance is restarted? (Choose two.)
A. The MEMORY_MAX_TARGET parameter is automatically set to 500 MB.
B. The value of the MEMORY_MAX_TARGET parameter remains zero till it is changed manually.

D. The lower bounds of PGA_AGGREGATE_TARGET and SGA_TARGET parameters are set to 90
MB and 270 MB, respectively.
Evaluate the following SQL statement used to create the PRODUCTS table:
CREATE TABLE products
(product_id NUMBER(3) PRIMARY KEY,

(PARTITION p1 VALUES LESS THAN (100000),
PARTITION p2 VALUES LESS THAN (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.

B. The failure ID has not been mentioned in the command for data file 5.
C. There are new failures recorded in the Automatic Diagnostic Repository (ADR).
D. The ADVISE FAILURE command has not been issued before the REPAIR FAILURE command.

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;

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.
Evaluate the following command:
SQL> CREATE TABLE design_data (id NUMBER,
LOB(doc) STORE AS SECUREFILE(DEDUPLICATE);

B. The LOB values are cached by default in the buffer cache.
C. The LOB values are automatically stored in encrypted mode.
D. All LOB data that is identical in two or more rows in a LOB column share the same data blocks.
You are working on the APPDB database as a DBA. The database has a default Flashback Data Archive DFLA1 created on it.

What is the effect of this command?
A. The tablespace having Flashback Archive is dropped.
B. The Flashback Archive FLA1 is dropped only if it is empty.
C. The Flashback Data Archive and historical data are dropped.
