QUESTION NO: 1
Your database supports an OLTP system.
Examine the parameter values configured in your database:

COUNTRY_ID column contains only three possible values: 1111, 2222, and 3333.
You execute the commands:
SQL> EXECUTE DBMS_STATS.GATHER_TABLE_STATS('SH','CUSTOMERS');
PL/SQL procedure successfully completed.
SQL> CREATE INDEX COUNTRY_IDX ON CUSTOMERS (COUNTRY_ID);
Index created.
You then perform a series of INSERT, UPDATE, and DELETE operations on the table.
View the Exhibit to examine the query and its execution plan.
Which three options would improve the performance of the query? (Choose three.)
A. creating a histogram on the COUNTRY_ID column
B. creating a SQL profile
C. regathering statistics on the CUSTOMERS table
D. increasing the size of the PGA
E. creating a KEEP cache
F. creating a bitmap index on the COUNTRY_ID column
Answer: A,C,D

QUESTION NO: 2
Which two statements are true about ADDM? (Choose two.)
A. It documents only those components and wait classes that are significantly impacting the performance of the database.
B. It first identifies the performance symptoms, and then refines them to reach the root cause with the singular aim of reducing the DB CPU metric.
C. It analyzes the performance of a database instance based on the time period covered by the most recent AWR snapshot, and generates recommendations based on hard-coded criteria.
D. It can analyze performance issues that occurred in past events provided they fall within the AWR retention period.
E. ADDM resource utilization and cost of analysis depends on the actual load on the database and the number of performance problems analyzed.
Answer: A,B

QUESTION NO: 3

E. to analyze the impact of new indexes and materialized views on the SQL statements executed by an application
F. to identify SQL statements that require SQL profiles
Answer: A,D,F

QUESTION NO: 4

2. Create a baseline template.
3. Create a new moving window baseline.
4. Increase the retention period default value to 30 days.
5. Increase the size of the existing moving window baseline to 30 days.
