Your multitenant container database (CDB) CDB1that is running in ARCHIVELOGmode contains two pluggable databases (PDBs), PDB2_1and PDB2_2, both of which are open. RMAN is connected to the target pluggable database PDB2_1.
RMAN> BACKUP DATABASE PLUS ARCHIVELOG DELETE INPUT;
Which statement is true about the execution of this command to back up the database?

In your multitenant container database (CDB) that contains pluggable databases (PDBs), the hr user executes the following commands to create and grant privileges on a procedure:
CREATEORREPLACEPROCEDUREcreate_test_v(v_emp_idNUMBER,v_enameVARCHAR2,
v_SALARYNUMBER,v_dept_idNUMBER)
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_v procedure from inserting values into tables on which they do not have any privileges?
