NO.1 View Exhibit1 and examine the indexes on the CUSTOMERS table.
The statistics for the CUSTOMERS table have been updated recently by using the following command:
SQL> EXEC DBMS_STATS.GATHER_TABLE_STATS('SH','CUSTOMERS',method_opt=>'FOR ALL
INDEXED COLUMNS SIZE AUTO');
View Exhibit2 to examine a query plan. Even though the index is present on the COUNTRY_ID and
CUST_GENDER columns, the query uses a full table scan. What could be the reason?
A. because the histogram statistics for the COUNTRY_ID column are not updated
B. because the DB_FILE_MULTIBLOCK_READ_COUNT initialization parameter is set to a high value
C. because the optimizer calculates the cost of accessing blocks by using a full table scan to be less as
compared to index scans, even though indexes are available
D. because indexes on CUST_GENDER and COUNTRY_ID columns are of different types, the index on
the CUST_GENDER column is bitmap index, and on COUNTRY_ID columns is btree index.

NO.2 A user in a session executed the following SQL statement to set the optimizer mode:
ALTER SESSION SET OPTIMIZER_MODE = ALL_ROWS
What impact would it have on the goal of the optimizer for that session? (Choose all that apply.)
A. Statement level OPTIMIZER_MODE hints take precedence over the session-level setting.
B. The OPTIMIZER_MODE parameter set at instance level takes precedence over the session-level
value.
C. The optimizer uses a cost-based approach, regardless of the presence of statistics; it optimizes with a
goal of best response time.
D. The optimizer uses a cost-based approach for all SQL statements in the session, regardless of the
presence of statistics; it optimizes with a goal of best throughput.

NO.3 You are working on an online transaction processing (OLTP) system. By day most of the application
users perform queries accessing the most recently added or modified rows. The applications have most
of the queries based on multiple tables. But at night, some batch processing is also done.
Which two actions would you recommend to choose a goal for the optimizer based on the needs of your
application? (Choose two.)
A.setting the OPTIMIZER_MODE parameter to ALL_ROWS at the instance level
B.setting the OPTIMIZER_MODE parameter to FIRST_ROWS_n at the instance level
C.asking the developer to add a hint /*ALL_ROWS*/ in the long-running batch processing queries
D.asking the developer to add a hint /*FIRST_ROWS_n*/ in the long-running batch processing queries

NO.4 View Exhibit1 to examine the description of the CUSTOMERS table.
You observed that optimizer selectivity is not accurate when the CUST_STATE_PROVINCE and
COUNTRY_ID columns are used together in the WHERE clause of a query.
View Exhibit2 to examine the query execution plan and the commands executed to gather the statistics.
The optimizer predicts that 20 rows will be processed rather than the 3,341 rows, which is the actual
number of rows returned from the table.
What can you do to make the optimizer detect the actual number of rows?
A. Set the STATISTICS_LEVEL parameter to ALL.
B. Set the OPTIMIZER_USE_PENDING_STATISTICS parameter to FALSE.
C. Create extended statistics for the CUST_STATE_PROVINCE and COUNTRY_ID columns.
D. Increase the STALE_PERCENT value for the CUSTOMERS table by using the
DBMS_STATS.SET_TABLE_PREFS procedure.

NO.5 View Exhibit1 to examine the description of the CUSTOMERS table.
The CUSTOMERS table has been updated heavily today. In a frequently used SQL statement, you notice
that estimated rows and the actual number of rows fetched differ greatly. The COUNTRY_ID column has
an index.
View Exhibit2 and examine the query execution plan.
What would you recommend to improve the optimizer's estimation?
A. setting the STATISTICS_LEVEL parameter to ALL
B. setting the OPTIMIZER_USE_PENDING_STATISTICS parameter to FALSE
C. creating extended statistics for the CUST_LAST_NAME, CUST_ID, and CUST_TOTAL columns
D. updating the statistics for the CUSTOMERS table by using the
DBMS_STATS.GATHER_TABLE_STATS
procedure

NO.6 You are working on an online transaction processing (OLTP) system. You detected free buffer waits
events for your database instance running in a machine that has multiple CPUs. You increased the
database buffer cache size as the first step. After a few hours of work on the database, further
investigation shows that the same event is being recorded.
What would be your next step to avoid this event in future?
A. Decrease the value of the DBWR_IO_SLAVES parameter.
B. Set the USE_INDIRECT_DATA_BUFFERS parameter to TRUE.
C. Increase the value of the DB_WRITER_PROCESSES parameter.
D. Increase the value of the DB_FILE_MULTIBLOCK_READ_COUNT parameter.

NO.7 The columns CUST_CITY, CUST_STATE_PROVINCE, and COUNTRY_ID are frequently used
together in the WHERE clause of the queries. The CUSTOMERS table is a big table with 20 GB of data.
You notice that the selectivity for these three columns varies from the selectivity that the optimizer
calculates.
What would you recommend to influence the selectivity calculated by the optimizer?
A. creating function-based indexes by concatenating all the columns
B. updating histogram statistics for these columns by using the DBMS_STATS.GATHER_TABLE_STATS
procedure
C. using the DBMS_STATS.CREATE_EXTENDED_STATS function to create a virtual column and create
index on the virtual column
D. using the DBMS_STATS.CREATE_EXTENDED_STATS function to create a virtual column and the
DBMS_STATS.GATHER_TABLE_STATS procedure to collect statistics on the virtual column
