A.CDB1 is in MOUNT state

B.CDB1 is shut down.

A.the physical data model

B.defining foreign keys for all tables to speed up joins

C.using check constraints to speed up updates

D.the configuration of storage arrays

A.It is performed automatically while the database remains in mount state. Then the database is opened.

B.It is performed automatically after the database is opened; however, blocks requiring recovery are not available until they are recovered.

C.It is not possible if an archived log is missing.

D.It is performed by the Recovery Writer (rvwr) background process.

E.Setting fast_start_mttr_target to a lower value reduces instance recovery time by causing dirty buffers to be written to disk more frequently, thereby reducing the number of I/Os needed during instance recovery.

F.Setting fast_start_mttr_target to a higher value reduces instance recovery time by causing the log writer to write more frequently, thereby reducing the number of I/Os needed during instance recovery.

A.It is not required in an application container.

B.It cannot be dropped from its application container.

C.It is automatically synchronized with its application root PDB when an application is upgraded.

D.A new application PDB created by cloning an application seed PDB can have an old version of the application installed after cloning completes.

E.It is automatically synchronized with its application root PDB when an application is installed.

F.A new application PDB created by cloning an application seed PDB can have an up-to-date version of the application installed after cloning completes.

G.It cannot be added to an application container after the application container has already been created.

A.The NOREDO clause must be used if the backups of the database being duplicated were taken when the database was in NOARCHIVELOG mode.

B.RMAN disk-based backups of the database to be duplicated can be used by the auxiliary instance.

C.The UNDO TABLESPACE clause is always required when no connection exists to the recovery catalog and the TARGET database is closed.

D.The UNDO TABLESPACE clause is always required when no connection exists to the TARGET instance.

E.The NOREDO clause can be used if the backups of the database being duplicated were taken when the database was in ARCHIVELOG mode.

F.RMAN SBT-based backups of the database to be duplicated can be used by the auxiliary instance.

G.The UNDO TABLESPACE clause is always required when no connection exists to the recovery catalog and the TARGET database is opened.

H.RMAN "pushes" the backups of the database to be duplicated over the network to the auxiliary instance.
