NO.11 Table T1 was created by executing the following statement:
CREATE TABLE t1
(deptno CHAR(2) NOT NULL,
deptname VARCHAR(36) NOT NULL,
empno CHAR(3) NOT NULL)
Immediately after creation, table T1 was populated with 10 rows. Later, user USER1 ran an application
that inserted 100,000 rows into table T1.
The following query is frequently ran against the T1 table:
SELECT deptno, empno, deptname FROM t1 WHERE deptno = 'EN' AND empno = '123'
Assuming current statics exist for the table and index, which index will provide optimal performance for
this query?
A. CREATE INDEX idx1 ON t1 (deptno, empno) INCLUDE (deptname)
B. CREATE INDEX idx1 ON t1 (deptno, empno)
C. CREATE INDEX idx1 ON t1 (deptno) INCLUDE (empno)

NO.12 A table named TAB_A was created with the COMPRESS YES option specified and populated with
100,000 rows. If a DBA wants to create an index on table TAB_A, which statement is true?
A. In order for the index to be compressed, it must be enabled for compression by specifying the
COMPRESS YES option with the CREATE INDEX statement that is used to create it.
B. The index will automatically be compressed since the table it is associated with is compressed; the
ALTER INDEX command does not have to be executed.
C. In order for the index to be compressed, it must be enabled for compression by specifying the
COMPRESS YES option in the CREATE INDEX statement used to create it; however, the index will not
be compressed until the ALTER INDEX command is used to create an index compression dictionary.
D. The index will automatically be enabled for compression because the associated table is compressed;
however, the index will not be compressed until it is REORGed.
