NEW QUESTION 31
Choose two. In which two situations can you use Database Upgrade Assistant?
- A. when the target and source database are on the same platform
- B. when a character set conversion is required during the upgrade
- C. when the operating system (OS) needs to be changed as part of the upgrade
- D. when multiple pluggable databases in a container database have to be upgraded in a specific sequence
- E. when the hardware platform needs to be changed as part of the upgrade
NEW QUESTION 32
Which two are true about Rapid Home Provisioning (RHP), which has been available since Orcale 18c? (Choose two.)
- A. It can be used to provision middleware.
- B. It cannot be used to upgrade Oracle Database homes.
- C. It can be used to patch Grid Infrastructure homes containing Oracle Restart.
- D. It can be used to provision applications.
- E. It is an Oracle Database service
NEW QUESTION 33
Which two are true about changing the LOCAL_UNDO_ENABLED property to false in a CDB? (Choose two.)
- A. After the change, only a common user with the required privilege can create an undo tablespace in CDB&ROOT.
- B. After the change, any user with the required privilege can create an undo tablespace in the PDBs.
- C. After the change, each existing PDB has to be reopened for the new undo mode to take effect.
- D. After the change, only one undo tablespace can exist in CDB$ROOT.
- E. Any new PDB and existing PDBs are automatically configured to use the default undo tablespace in CDB$ROOT.
- F. Undo tablespaces existing in PDBs must be dropped before the change.
You can set a CDB in local UNDO mode either at CDB creation or by altering the CDB property. When the database property LOCAL_UNDO_ENABLE is FALSE, which is the default, there is only one UNDO tablespace that is created in the CDB root, and that is shared by all containers. When LOCAL_UNDO_ENABLE is TRUE, every container in the CDB uses local undo and each PDB must have its own local UNDO tablespace. To maintain ease of management and provisioning, UNDO tablespace creation happens automatically and does not require any action from the user. When a PDB is opened and an UNDO tablespace is not available, its automatically created.
NEW QUESTION 34
A database is configured in ARCHIVELOG mode.
Full RMAN backups are taken and no backup to trace has been taken of the control file. A media failure has occurred.

- B. after losing an archived log from after the most recent backup
- C. when any archived log from, before, or after the most recent backup is corrupt.
- D. after losing all copies of the control file
- E. after losing an archived log from before the most recent backup
NEW QUESTION 35

- C. Executing DBMS_STATS.GATHER_DATABASE_STATS while connected to CDB$ROOT gathers object statistics in all open pluggable databases (PDBs).
- D. System statistics can be gathered only while the CDB is in MOUNT state.
- E. Executing DBMS_STATS.GATHER_DATABASE_STATS while connected to CDB$ROOT gathers object statistics only in CDB$ROOT.
