Q1. View the Exhibit and examine the data in EMP and DEPT tables.
In the DEPT table, DEPTNO is the PRIMARY KEY.
In the EMP table, EMPNO is the PRIMARY KEY and DEPTNO is the FOREIGN KEY referencing the DEPTNO column in the DEPT table.
What would be the outcome of the following statements executed in the given sequence?
DROP TABLE emp;
FLASHBACK TABLE emp TO BEFORE DROP;
INSERT INTO emp VALUES (2,COTT 10); INSERT INTO emp VALUES (3,ING 55);
A. Both the INSERT statements would fail because all constraints are automatically retrieved when the table is flashed back.
B. Both the INSERT statements would succeed because none of the constraints on the table are automatically retrieved when the table is flashed back.
C. Only the first INSERT statement would succeed because all the constraints except the primary key constraint are automatically retrieved after a table is flashed back.
D. Only the second INSERT statement would succeed because all the constraints except referential integrity constraints that reference other tables are retrieved automatically after the table is flashed back.
Answer: D

Q3. View the Exhibit and examine the structure of EMPLOYEES and JOB_IHISTORY tables.
The EMPLOYEES table maintains the most recent information regarding salary, department, and job for all the employees. The JOB_HISTORY table maintains the record for all the job changes for the employees. You want to delete all the records from the JOB_HISTORY table that are repeated in the EMPLOYEES table.
Which two SQL statements can you execute to accomplish the task? (Choose two.)
A. DELETE FROM job_history j WHERE employee_id = (SELECT employee_id FROM employees e WHERE j.employee_id = e.employee_id) AND job _id = (SELECT job _id FROM employees e WHERE j.job_id = e.job_id);
B. DELETE FROM job_history j WHERE (employee_id, job _id) = ALL (SELECT employee_id, job_id FROM employees e WHERE j.employee_id = e.employee_id and j.job_id = e.job_id)
C. DELETE FROM job_history j WHERE employee_id = (SELECT employee_id
FROM employees e
WHERE j.employee_id = e.employee_id and j.job_id = e.job_id)
D. DELETE FROM job_history j WHERE (employee_id, job _id) = (SELECT employee_id, job_id FROM employees e WHERE j.employee_id = e.employee_id and j.job_id = e.job_id)
Answer: C,D
Q4. View the Exhibit and examine the descriptions of the EMPLOYEES and DEPARTMENTS tables.
The following SQL statement was executed:

GROUPING(e. department_id) GRP_DEPT,
GROUPING(e.job_id) GRPJOB,
GROUPING(d. location_id) GRP_LOC
FROM employees e JOIN departments d
ON e.department_id = d.department_id
GROUP BY ROLLUP (e.department_id, e.job_id, d.location_id);
View the Exhibit2 and examine the output of the command.
Which two statements are true regarding the output? (Choose two.)
A. The value1in GRP_LOC means that the LOCATION_ID column is taken into account to generate the subtotal.
B. The value 1 in GRPJOBandGRP_LOC meansthatJOB_IDandLOCATION_ID columns are nottakeninto accountto generatethesubtotal.
C. Thevalue1inGRPJOB and GRP_LOC meansthatthe NULL value in JOBJD and LOCATIONJD columns aretakeninto account togeneratethe subtotal.
D. The value 0 inGRP_DEPT,GRPJOB, and GRP_LOC means that DEPARTMENT_ID, JOB_ID, and LOCATION_ID columnsaretaken into account to generate the subtotal
