A.It cannot be dropped from its application container.

B.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.

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

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

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

F.It is not required in an application container.

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

A.Automatically tuned and resized System Global Area components will always revert to their initial sizes after an instance restart.

B.With Automatic Memory Management, the database instance can increase the System Global Area size by reducing the Program Global Area size.

C.With Automatic Shared Memory Management, the database instance can increase the Program Global Area size by reducing the System Global Area size.

D.On Line Transaction Processing systems often use less Program Global Area than Decision Support Systems.

E.With Automatic Shared Memory Management, the database instance can increase the Large Pool size by reducing the Shared Pool size.

F.Automatic Memory Management must be used together with locking the System Global Area into physical memory.

A.Flashback logs are monitored and proactively deleted when beyond the retention period definedin db_flashback_retention_target before there is space pressure.

B.Flashback logs are automatically purged when db_flashback_retention_target is set lower than the time they have already been retained.

C.Flashback logs are monitored and proactively deleted when beyond the retention period definedin DB_flashback_retention_TARGET only after there is space pressure

D.Flashback logs are automatically purged whenever the value Of DB_FLASHBACK_RETENTION_TARGET is changed.

E.Flashback logs are monitored for being older than the retention period defined in db_flashback_retention_target and can be deleted by an administrator written event trigger.

A.The database instance memory should always be tuned before tuning any file systems.

B.The alert log should be used to find the database and instance areas most in need of tuning.

C.Tuning activities should stop once agreed service levels for performance have been met.

D.Tuning activities should stop once the user is satisfied with performance.

E.The Oracle Database time model should be used to find the database and instance areas most in need of tuning.

F.SQL statements should always be tuned before tuning any file systems.

A.If an RMAN BACKUP VALIDATE command 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 asynchronous I/O/

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

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

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

F.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.

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