                                                          Oracle Database Administration II Sample Questions (Q72-Q77):

                                                          NEW QUESTION # 72

                                                          SQL> AUDIT POLICY sales_pol;
                                                          Which statement is true about SALES_POL?

                                                          Answer: A


                                                          NEW QUESTION # 73
                                                          Choose the best answer.

SQL> col name for a10 SQL> select name, open_mode from v$pdbs; NAME OPEN_MODE ---------------------------------------PDB$SEED READ ONLY PDB1 READ WRITE PDB2 MOUNTED SQL> exit Next you execute: $ expdp system/oracle full=y What is the outcome?

                                                          Answer: C


                                                          NEW QUESTION # 74
                                                          Which three actions are performed by the Oracle Preinstallation RPM, oracle-database-server-xxxx- preinstall, for Oracle Grid Infrastructure, where xxxx is the Oracle version and release? (Choose three.)

                                                          Answer: A,C,E


                                                          NEW QUESTION # 75
                                                          Which two are true about creating RMAN backups for an Oracle container database? (Choose two.)

                                                          Answer: B,D

                                                          Explanation:
                                                          A - FALSE. The ARCH process backs up online redo logs (by creating Arch redo logs), never the DBA. DBAs backup Archive Redo Logs, not online redo logs.
                                                          B - TRUE. Control files are DB wide - backing them up, from the Container Root, is exactly where you do this.
                                                          C - TRUE. Part of the point of Multitenant is that you have control of all PDBs from the CDB level.
                                                          D - FALSE. An application root container is still below the main Container, so you cannot administer control files from here.
                                                          E - FALSE. For the same reason as above, you can only create control file backups from the Root Container.


                                                          NEW QUESTION # 76
                                                          Which two are true about the execution of operating system scripts starting from Oracle Database 19c?

                                                          Answer: B,D


                                                          NEW QUESTION # 77
