* The size of the extent map that defines a file can be smaller by a factor of 8 and 64 depending on the file size. The initial extent size is equal to the allocation unit size and it increases by a factor of 8 and 64 at predefined thresholds. This feature is automatic for newly created and resized datafiles when the disk group compatibility attributes are set to Oracle Release 11 or higher. QUESTION 63 You executed a DROP USER CASCADE on an Oracle 11g release 1 database and immediately realized that you forgot to copy the OCA.EXAM_RESULTS table to the OCP schema. The RECYCLE_BIN enabled before the DROP USER was executed and the OCP user has been granted the FLASHBACK ANY TABLE system privilege. What is the quickest way to recover the contents of the OCA.EXAM_RESULTS table to the OCP schema? A. Execute FLASHBACK TABLE OCA.EXAM_RESULTS TO BEFORE DROP RENAME TO OCP.EXAM_RESULTS; connected as SYSTEM. B. Recover the table using traditional Tablespace Point In Time Recovery. C. Recover the table using Automated Tablespace Point In Time Recovery. D. Recovery the table using Database Point In Time Recovery. E. Execute FLASHBACK TABLE OCA.EXAM_RESULTS TO BEFORE DROP RENAME TO EXAM_RESULTS; connected as the OCP user. Correct Answer: C Section: (none) Explanation Explanation/Reference: Explanation: RMAN tablespace point-in-time recovery (TSPITR). Recovery Manager (RMAN) TSPITR enables quick recovery of one or more tablespaces in a database to an earlier time without affecting the rest of the tablespaces and objects in the database. Fully Automated (the default) In this mode, RMAN manages the entire TSPITR process including the auxiliary instance. You specify the tablespaces of the recovery set, an auxiliary destination, the target time, and you allow RMAN to manage all other aspects of TSPITR. The default mode is recommended unless you specifically need more control over the location of recovery set files after TSPITR, auxiliary set files during TSPITR, channel settings and parameters or some other aspect of your auxiliary instance. QUESTION 64 In your multitenant container database (CDB) containing pluggable database (PDBs), the HR user executes the following commands to create and grant privileges on a procedure: CREATE OR REPLACE PROCEDURE create_test_v (v_emp_id NUMBER, v_ename VARCHAR2, v_SALARY NUMBER, v_dept_id NUMBER) BEGIN INSERT INTO hr.test VALUES (V_emp_id, V_ename, V_salary, V_dept_id);

END; / GRANT EXECUTE ON CREATE_TEST TO john, jim, smith, king; How can you prevent users having the EXECUTE privilege on the CREATE_TEST procedure from inserting values into tables on which they do not have any privileges? A. Create the CREATE_TEST procedure with definer’s rights. B. Grant the EXECUTE privilege to users with GRANT OPTION on the CREATE_TEST procedure.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
