Question 1

Examine this configuration:
1. CDB1 is a container database.
2. APP_ROOT is an application root in CDB1.
3. APP_PDB1 is an application PDB in APP_ROOT.
4. FLASHBACK DATABASE is ON.
You execute these commands:
Which table or set of tables will exist after the Flashback operation has completed?

A.CDB1_TAB and APP_ROOT_TAB

B.CDB1_TAB, APP_ROOT_TAB, and APP_PDB1_TAB

C.CDB1_TAB only

D.CDB1_TAB and APP_PDB1_TAB

E.none of the tables, because all three tables will be dropped

Question 2

A database is configured in ARCHIVE LOG mode. A full RMAN backup exists but no control file backup to trace has been taken. A media failure has occurred. In which two scenarios is incomplete recovery required? (Choose two.)

A.after losing an UNDO tablespace that is in use

B.after losing a SYSAUX tablespace data file

C.after losing all members of the CURRENT online redo log group

D.after losing all members of an INACTIVE online redo log group

E.after losing all copies of the control file

Question 3

For which two requirements can you use the USER_TABLESPACE clause with the CREATE PLUGGABLE DATABASE command? (Choose two.)

A.to include specific user tablespaces only when relocating a PDB

B.to specify a default tablespace in a PDB cloned from another PDB in the same CDB.

C.to exclude all tablespaces except SYSTEM, SYSAUX, and TEMP when plugging in a PDB

D.to specify the list of tablespaces to include when creating a PDB from the CDB seed

E.to specify the list of user tablespaces to include when moving a non-CDB to a PDB

F.to exclude a temp tablespace when plugging in a PDB

Question 4

Which two are true about creating pluggable databases (PDBs) using snapshots in Oracle 19c and later releases? (Choose two.)

A.A PDB snapshot is always a full copy of the source PDB.

B.A PDB snapshot is always a sparse copy of the source PDB.

C.A snapshot copy PDB depends on a storage snapshot which can only be stored on specific file systems.

D.A PDB snapshot depends on a storage snapshot which can be stored on any file system.

E.A PDB snapshot depends on a storage snapshot which can only be stored on specific file systems.

F.A snapshot copy PDB depends on a storage snapshot which can be stored on any file system.

G.A snapshot copy PDB can be created from a stand-alone clone PDB.

Question 5

Which four are true about a Recovery Manager (RMAN) duplication without a TARGET connection? (Choose four.)

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 SBT-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 TARGET instance.

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

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

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

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

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