QUESTION NO: 2
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

PL/SQL procedure successfully completed.
SQL> CREATE INDEX COUNTRY_IDX ON CUSTOMERS (COUNTRY_ID);
Index created.
