The LOCAL_UNDO_ENABLED database property is set to FALSE in the CDB. Data file 24 of PDB2 was deleted and you need to restore and recover it. The only RMAN backup that exists was created with the BACKUP DATABASE command while connected to CDB$ROOT. Which three are true? (Choose three.)

                                                          Answer: A,E

                                                          Explanation:
                                                          Explanation
                                                          You can use rhpctl move gihome command with the same syntax to switch from the current Oracle Grid Infrastructure home to a patched home. The rhpctl command enables you to switch from your current Oracle Grid Infrastructure or Oracle Database home to patched Oracle home so that you can provision the new Oracle home as gold image. You can also use the rhpctl command to switch back to the old Oracle home, if you want to roll back the operation.


                                                          NEW QUESTION # 136
                                                          Which two are true about creating RMAN backups for an Oracle container database? (Choose two.)

                                                          Answer: A,E

                                                          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.
