Answer: AB
Q6. The user HR owns the EMP table. The user HR grants privileges to the user SCOTT by using this command:
Which statement is true after HR issues the REVOKE command?
A. The command fails because SCOTT still has privileges.
B. The command succeeds and privileges are revoked from JIM.
C. The command fails because HR cannot revoke the privileges from JIM.
D. The command succeeds and only HR has the privilege to perform the SELECT, INSERT, and UPDATE operations on the EMP table.
Answer: C
Q7. Your database instance is functional for the past one month. The Automatic Workload Repository (AWR) snapshot retention is set to 7 and the STATISTICS_LEVEL initialization parameter is set to TYPICAL. You receive a complaint about the poor performance of the database between 7 PM and 9 PM of the previous day. Choose two actions any of which can be referred to first to diagnose the problem. (Choose two.)
A. Use the Active Session History report.
B. Use the AWR Compare Periods report.
C. Use an ADDM analysis between 7 PM and 9 PM of the previous day.
D. Use the AWR Compare Period report between 7 PM and 9 PM of the previous day.
Answer: BC
Q8. Your database instance is running with full workload after database creation. You have decided to use a fixedsize undo tablespace. You want to use the undo Advisor to estimate the capacity of the undo tablespace.
Which two factors must you consider before using the Undo Advisor to estimate the capacity of the undo tablespace? (Choose two.)
A. The retention period to support flashback
B. The expected length of the longest-running query
C. The number of undo tablespaces in the database
D. The size of the Flash Recovery Area for the database instance
Answer: AB
Q9. Which two statements are true about the Automatic Database Diagnostic Monitor (ADDM)? (Choose two.)
A. The ADDM requires at least four AWR snapshots for analysis
B. The ADDM runs after each AWR snapshot is collected automatically by MMON
C. The results of the ADDM analysis are stored in the Automatic Workload Repository (AWR)
D. The ADDM analysis provides only diagnostics information but does not provide recommendations
E. The ADDM calls other advisors if required, but does not provide recommendations about the advisors
Answer: BC
Q10. View the Exhibit to examine the output produced by the following query at three different times since the database instance started and has experienced workloads of different capacities:
SQL> SELECT substr(component, 0, 10) COMP, current_size CS, user_specified_size US
FROM v$memory_dynamic_components
WHERE current_size!=0;
What do you infer from this?
Exhibit:
A. The database instance is running with manual PGA management.
B. The database instance is running with manual shared memory management.
C. The database instance has the MEMORY_TARGET value set to a nonzero value.
D. All sessions are connected to the database instance in dedicated mode, and no RMAN or parallel query operations have been performed.
Answer: C
Q11. The HR user creates a stand-alone procedure as follows and grants the EXECUTE privilege on the procedure to many database users:
CREATE OR REPLACE PROCEDURE create_dept ( v_deptno NUMBER, v_dname VARCHAR2,
v_mgr NUMBER, v_loc NUMBER)
BEGIN
INSERT INTO hr.departments VALUES (v_deptno, v_dname, v_mgr, v_loc);
END;
The users having permission to execute the procedure are able to insert records into the
DEPARTMENTS table even though they do not have the INSERT privilege on the table. You want only those users who have privileges on the DEPARTMENTS table to be able to execute the procedure successfully.
What would you suggest to the PL/SQL developers to achieve this?
A. Create the procedure with definer's right.
B. Create the procedure with invoker's right.
C. Grant the EXECUTE privilege with GRANT OPTION on the procedure to selected users.
D. Create the procedure as part of a PL/SQL package and grant the EXECUTE privilege on the package to selected users.
Answer: B
Q12. Which two statements are true regarding the SGA_TARGET initialization parameter? (Choose two.)
A. It can be increased up to the value of the SGA_MAX_SIZE parameter.
B. Increasing the value of the SGA_TARGET parameter distributes the increased memory among all the autotuned components.
C. Reducing the value of the SGA_TARGET parameter deallocates memory from both autotuned and manually sized components.
D. Increasing the value of SGA_TARGET up to the value of SGA_MAX_SIZE disables the automatic shared memory management feature.
Answer: AB
Q13. Which two statements are true about setting the FAST_START_MTTR_TARGET initialization parameter to a nonzero value? (Choose two.)
A. The MTTR advisor will be disabled
B. Automatic checkpoint tuning will be enabled
C. The value for the LOG_CHECKPOINT_INTERVAL initialization parameter will be override the value for FAST_START_MTTR_TARGET
D. The time taken to recover the instance after the crash is always exactly the same as the value given for the FAST_START_MTTR_TARGET initialization parameter
Answer: BC
