Question 211

Which two are true about a Recovery Manager (RMAN) duplication without a target connection?

A.The undo tablespace clause is always required when no connection exists to the recovery catalog and the target database is closed.

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 target instance.

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

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

Question 212

While backing up to the Oracle Fast Recovery Area (FRA), you determined the backup is taking too long and suspect a performance bottleneck.
Which three are true about diagnosing and tuning these problems? (Choose three.)

A.If an RMAN BACKUP VALIDATEcommand takes roughly the same time as an actual backup, then both read and write I/O are likely bottlenecks.

B.Setting DBWR_IO_SLAVESto a non zero value can improve backup performance when using synchronous I/O.

C.If an RMAN BACKUP VALIDATEcommand takes noticeably less than an actual backup, then write I/O is a likely bottleneck.

D.If an RMAN BACKUP VALIDATEcommand takes roughly the same time as an actual backup, then read I/O is a likely bottleneck.

E.Data files with a high value in V$BACKUP_SYNC_IO.DISCRETE_BYTES_PER_SECONDare a potential performance bottleneck when synchronous I/O is used.

F.Setting DBWR_IO_SLAVESto a non zero value can improve backup performance when using asynchronous I/O/

G.Data files with a high value in V$BACKUP_ASYNC_IO.SHORT_WAITSare a potential performance bottleneck when asynchronous I/O is used.

Question 213

Choose the best answer. You want to transport the UNIVERSITY tablespace from one database to another. The UNIVERSITY tablespace is currently open read/write. The source and destination platforms have the same endian Examine this list of steps:. 1. Make the UNIVERSITY tablespace read-only on the source 2. Export the UNIVERSITY tablespace metadata using EXPDP. 3. Create a cross-platform backup set from the UNIVERSITY source system, using an RMAN command that includes the DATAPUMP clause. 4. Copy the cross-platform backup sets to the destination system. 5. Copy the Data Pump dump set from the source to the destination system. 6. Restore the cross-platform backup set on the destination system using an RMAN command that includes the DATAPUMP clause. 7. Import the UNIVERSITY tablespace metadata using IMPDP. 8. Make the UNIVERSITY tablespace read/write on the destination system. Which are the minimum number of steps required, in the correct order, to transport the UNIVERSITY tablespace?

A.3,4,6

B.1,2,3,4,5,6,7,8

C.2,3,4,5,6,7

D.1,3,4,6,8

Question 214

Which three are true? (Choose three.)

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

B.Application-common Transparent Security Data Protection (TSDP) policies can be created only within an application install/patch BEGIN-END block.

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

D.Application-common Oracle Label Security (OLS) policies cannot be created in an application root outside an install/patch BEGIN-END block.

E.Application-common OLS policies can be created in an application root inside an install/patch BEGIN-END block.

F.Application-common TSDP policies are always container specific.

G.Virtual Private Database (VPD) policies on objects in an application root are automatically synchronized with all application PDBs contained in the application container.

Question 215

Which two are true about RMAN persistent configuration settings, administration, and their effects?

A.Backups written to the fast recovery area (FRA) that are obsolete based on the redundancy retention policy can be deleted automatically to free space.

B.A DBA must specify either a redundancy retention policy or a recovery window retention policy.

C.A target database's persistent RMAN configuration settings are always synchronized automatically with the RMAN catalog.

D.Backups older than the recovery window retention policy are always deleted automatically if the backup location has insufficient space.

E.A target database's persistent RMAN configuration settings are always stored in the target's control file
