NO.2 You are working on a development database that was upgraded to Oracle Database 11g from Oracle
Database 9i. An ADDM finding in this database says that the shared pool is inadequately sized, as shown
in the Exhibit.
You diagnosed that this is due to different kinds of workloads and this occurs only during peak hours. You
tried to resize this by shrinking the database buffer cache but that caused inadequate buffer cache
problems. The following are the related parameter settings:
SQL> show parameter sga
NAME TYPE VALUE
------------------------------ --------------- -----------------
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 300M
sga_target big integer 0
SQL> show parameter target
NAME TYPE VALUE
------------------------------ --------------- -----------------
.....
fast_start_mttr_target integer 0
memory_max_target big integer 0
memory_target big integer 0
pga_aggregate_target big integer 100M
sga_target big integer 0
You want to balance the memory between the System Global Area (SGA) components within SGA
without affecting the size of the Program Global Area (PGA).
Which action would solve this problem?
A. Set the SGA_TARGET parameter to 300M.
B. Set the SGA_MAX_SIZE parameter to 400M.
C. Set the MEMORY_TARGET parameter to 100M.
D. Set the MEMORY_MAX_TARGET parameter to 300M.

NO.10 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

NO.11 Examine the initialization parameter values for the instance given below:
NAME TYPE VALUE
------------------------------------ ----------- ------------------
optimizer_capture_sql_plan_baselines boolean FALSE
optimizer_dynamic_sampling integer 2
optimizer_features_enable string 11.1.0.6
optimizer_index_caching integer 0
optimizer_index_cost_adj integer 100
optimizer_mode string ALL_ROWS
db_file_multiblock_read_count integer 64
You notice that the one of the queries is using a full table scan (view Exhibit1) instead of index unique
scan (view Exhibit2). The index is present on the column that is accessed in the WHERE clause of the
query. The cost for a full table scan is more than that for an index unique scan.
Why would the optimizer choose full table scan over index unique scan? (Choose all that apply.)
A. The OPTIMIZER_INDEX_COST_ADJ initialization parameter is set to a low value.
B. The OPTIMIZER_INDEX_COST_ADJ initialization parameter is set to a high value.
C. The DB_FILE_MULTIBLOCK_READ_COUNT initialization parameter is set to a low value.
D. The statistics for the table and all the indexes associated with the table are not current.

NO.12 You are working on a decision support system (DSS). The index is available on the COUNTRY_ID
column of the CUSTOMERS table.
View the Exhibit and examine the parameter settings and the query execution plan.
Why is the query using a full table scan instead of an index scan?
A. because the histogram statistics for the COUNTRY_ID column are not updated
B. because the index statistics for the index on the COUNTRY_ID column are not current
C. because the DB_FILE_MULTIBLOCK_READ_COUNT initialization parameter is set to a higher value
D. because the optimizer predicts that most of the blocks in the table are accessed. Therefore, it uses a
full table scan, even though indexes are available.

NO.14 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.16 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.

NO.19 You observed that some of the queries are performing poorly on the SALES_RECORDS table in your
database.
On further investigation, you find that at the end of each day the contents of the SALES_RECORDS table
are transferred to the SALES table and deleted from the SALES_RECORDS table. The deleted
operations cause the table to be sparsely populated.
You decided to use the ALTER TABLE...SHRINK SPACE COMPACT command to shrink the table.
Why would you choose this method? (Choose all that apply.)
A. because it can be used during peak hours
B. because it avoids unnecessary cursor invalidation
C. because it adjusts the high-water mark (HWM) immediately
D. because you have long-running queries that might span the shrink operation
E. because it does not allow any data manipulation language (DML) operations, thereby making the
shrink
operation faster

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.
