Q19. Examine this configuration:
* CDB1 is a container database.
* PDB1 and PDB2 are pluggable databases in CDB1.
You execute these commands successfully:

Which two are true? (Choose two.)

 PDB1 and PDB2 are in MOUNT state.

 Redo logs are opened.

 PDB1 and PDB2 are in READ ONLY state.

 CDB$ROOT is in MOUNT state.

 PDB$SEED is in READ ONLY state.

Q20. Which two are true about data movement between a non-CDB and a PDB using Data Pump? (Choose two.)

 Tablespaces are automatically created as need while importing full exports in either a non-CDB or a PDB.

 Oracle attempts to convert conventional database users to local users when moving schemas from a non-CDB to a PDB.

 A new PDB is automatically created when importing a non-CDB into a CDB.

 Oracle attempts to convert common users to conventional users when moving schemas from a PDB to a non-CDB.

 Moving data from a PDB to a non-CDB is only possible by using transportable tablespace export and import.

 Moving data from a non-CDB to a PDB is only possible by using conventional export and import.

Q21. While backing up to an SBT channel, you determine that the read phase of your compressed Recovery Manager (RMAN) incremental level 0 backup is a bottleneck.
FORCE LOGGING is enabled for the database.
Which two could improve read performance? (Choose two.)

 Increase the size of tape I/O buffers.

 Disable FORCE LOGGING for the database.

 Increase the size of the database buffer cache.

 Enable asynchronous disk I/O.

 Increase the level of RMAN multiplexing.

Q22. Which two are true about poorly performing SQL statements and their tuning in Oracle database instances?
(Choose two.)

 SQL statements performing many physical I/Os can always have their performance improved by creating indexes.

 SQL statements doing only logical reads never require tuning because they do no physical I/O.

 The solution that best optimizes one SQL statement can degrade the performance of others.

 SQL statements doing joins always do more physical I/O than single table queries.

 Poorly performing SQL statements can be tuned automatically by the Oracle server.

Q23. Which two are true about instance recovery? (Choose two.)

 It is not possible if an archived log is missing.

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

 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.

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

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

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

Q24. Choose the best answer. How do you configure a CDB for local undo mode?

 Open the CDB instance in restricted mode. In CDB$ROOT, drop the UNDO tablespace. Execute ALTER DATABASE LOCAL UNDO ON in each PDB, and then restart the CDB instance.

 Open the CDB instance in upgrade mode. In CDB$ROOT, execute ALTER DATABASE LOCAL UNDO ON, and then restart the CDB instance.

 Open the CDB instance in upgrade mode. In each PDB, execute ALTER DATABASE LOCAL UNDO ON, create an UNDO tablespace, and then restart the CDB instance.

 Open the CDB instance in restricted mode. In CDB$ROOT, execute ALTER DATABASE LOCAL UNDO ON. create an UNDO tablespace in each PDB, and then restart the CDB instance.

 Open the CDB in read-only mode. In CDB$ROOT, execute ALTER DATABASE LOCAL UNDO ON, and then change the CDB to read/write mode.

Q25. Choose two. Which two are true about various Oracle security and auditing capabilities?

 Application-common Transparent Security Data Protection (TSDP) policies can be created only if all the PDBs in the application container are closed.

 Application-common TSDP policies are always container specific.

 Application-common OLS policies can be created only if all the PDBs in the application container are closed.

 Unified auditing can be automatically synchronized to all application PDBs in an application container.

 Fine-grained auditing (FGA) policies in an application root are automatically synchronized to all application PDBs contained in the application container when they are updated.

Q26. Which three are true about creating container databases (CDBs) and pluggable databases (PDBs) in Oracle
19c and later releases? (Choose three.)

 A PDB snapshot can be a sparse copy of a source PDB.

 A PDB snapshot depends on an existing storage snapshot of the source PDB.

 A CDB can be duplicated using Recovery Manager (RMAN) with no configuration required before starting the duplication.

 A CDB can be duplicated using the Database Configuration Assistant (DBCA) in silent mode with no configuration required before starting the duplication.

 A PDB snapshot can be a full copy of a source PDB.

 A snapshot copy PDB can be a full copy of a source PDB.

 A snapshot copy PDB does not depend on an existing storage snapshot of the source PDB.

Q27. Choose three. Which three are true about patchsets?

 They are installed via OPatch or OPatchAuto.

 A base release is not needed to install patchsets.

 They can be applied in a rolling fashion for Clusterware and the databases.

 Installing a patchset is considered an “upgrade.”

 They can introduce new features.

 They are only released quarterly.

Q28. Which three methods can be used for heap table data migration after upgrading a database? (Choose three.)

 using Database Replay

 using SQL Developer

 using Oracle Data Pump

 using operating system file copy utilities

 using Database Upgrade Assistant

 using the CREATE TABLE AS SELECT SQL statement

Q29. Which three are true about Oracle Grid Infrastructure for a Standalone Server?

 It includes both Oracle Restart and Oracle Automatic Storage Management (ASM) software.

 It creates one disk group during installation.

 It requires the operating system oracle_base environment variable to be predefined before installation.

 It requires Oracle ASM Filter Driver (ASMFD) to manage Automatic Storage Management (ASM) disks

 It requires Oracle ASMLibto manage Automatic Storage Management (ASM) disks.

 Automatic Storage Management (ASM) requires that O/S groups OSASM and OSDBA be assigned as secondary groups for its installation owner.

Q30. Choose two. Which two restrictions apply when the RMAN BACKUP AS COPY command is used to create a backup?

 Backups can be taken only if a fast recovery area is configured.

 Backups can be written only to disk.

 Backups can be taken only for data files.

 Binary compression cannot be applied to the backup.

 Backups can be written only if checksums are stored for each block.

 Backups can be written only to media.

Q31. Examine this configuration:
1. CDB1 is a container database.
2. PDB1 and PDB2 are pluggable databases in CDB1.

 Uncommitted transactions in CDB1 and PDB1 have been rolled back.

 CDB1 is shut down.

 CDB1 is in MOUNT state

 PDB2 will be MOUNTED.

 PDB1 will be MOUNTED.

 PDB$SEED will be opened READ ONLY.

 PDB2 will be opened READ WRITE.

 PDB1 will be opened READ WRITE.

 PDB$SEED will be MOUNTED.
