Your database supports an OLTP system.
Examine the parameter values configured in your database:
The CUSTOMERS table contains 8,000 rows. The CUST_ID column is the primary key and the
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

1. Create a fixed baseline.
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.
6. Create warning and critical alerts for the relevant metrics.
7. Enable adaptive thresholds to detect the workload patterns and specify a high-significance-level threshold type.
QUESTION NO: 5
