Question 106

Which three are true about RMAN persistent configuration settings, administration, and their effects? (Choose three.)

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

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

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

D.The RMAN SHOW ALLcommand displays only settings with nondefault values.

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

F.The V$RMAN_CONFIGURATIONview displays only settings with values that have been modified.

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

Question 107

Examine these queries and their output:

After a system crash, an instance restart and an attempted opening of the PDBs result in:

Which two are true?

A.Data file 24 must be recovered while PDB2 is closed.

B.Data file 24 cannot be recovered while the CDB is opened.

C.Data file 24 can be recovered while CDB$ROOTand PDB$SEED are opened.

D.Data file 24 must be recovered while the CDB is opened.

E.Data file 24 can be recovered while PDB2 is opened.

Question 108

Which two are true about automatic block repair?

A.Automatic block repair can repair blocks with no standby database if db_block_checking = TRUE.

B.It is not possible for media corrupt blocks.

C.Real-Time Query must be enabled on a physical standby database for automatic block repair to be done on its primary database.

D.Real-Time Query must be enabled on a primary database for automatic block repair to be done on any of its physical standby databases.

E.Real-Time Query must be enabled on a physical standby database for automatic block repair to be done on that physical standby database.

Question 109

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

A.Setting DBWR_IO_SLAVES to a non zero value can improve backup performance when using asynchronous I/O/

B.If an RMAN BACKUP VALIDATE command takesroughly the same time as an actual backup, then read I/O is a likely bottleneck.

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

D.If an RMAN BACKUP VALIDATE command takesroughly the same time as an actual backup, then both read and write I/O are likely bottlenecks.

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

F.If an RMAN BACKUP VALIDATE command takes noticeably lessthan an actual backup, then write I/O is a likely bottleneck.

G.Setting DBWR_IO_SLAVES to a non zero value can improve backup performance when using synchronous I/O.

Question 110

Examine this configuration:
CDB1 is an Oracle Database 12c Release 2 database containing pluggable databases PDB$SEED, PDB1, and PDB2.
PDB$SEED is open READ ONLY
PDB1 is open READ WRITE
PDB2 is MOUNTED.
ORACLE_HOME is /u01/app/oracle/product/18.1.0/dbhome_1.
You execute these commands before upgrading the database to the current release:

For which databases will fixup scripts be created?

A.CDB1, PDB$SEED, PDB1, and PDB2

B.CDB1 and PDB$SEED only

C.CDB1, PDB$SEED, and PDB1 only

D.CDB1, PDB1, and PDB2 only

E.PDB$SEED, PDB1, and PDB2 only
