NEW QUESTION # 55
Which two are true about flashback features in Oracle Database 19c and later releases? (Choose two.)
- A. Flashback logs are monitored and proactively deleted when beyond the retention period defined in DB_FLASHBACK_RETENTION_TARGETbefore there is space pressure.
- B. Flashback logs are monitored and proactively deleted when beyond the retention period defined in DB_FLASHBACK_RETENTION_TARGETonly after there is space pressure.
- C. 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.
- D. Flashback logs are automatically purged when DB_FLASHBACK_RETENTION_TARGETis set lower than the time they have already been retained.
- E. Flashback logs are automatically purged whenever the value of DB_FLASHBACK_RETENTION_TARGETis changed.
Answer: A,D
Explanation:
Starting with Oracle Database Release 19c, the management of space in the fast recovery area is simplified.
Oracle Database monitors flashback logs in the fast recovery area and automatically deletes flashback logs that are beyond the retention period.
When the retention target is reduced, flashback logs that are beyond the retention period are deleted immediately.
In scenarios where a sudden workload spike causes a large number of flashback logs to be created, the workload is monitored for a few days before deleting flashback logs that are beyond the retention period.
This avoids the overhead of recreating the flashback logs, if another peak workload occurs soon after.
NEW QUESTION # 56
Which three are true in Oracle 19c and later releases? (Choose three.)
- A. Tablespaces always remain in read/write mode during transportable tablespace operations.
- B. Simultaneous data pump jobs can be limited at the pluggable database (PDB) level.
- C. Tablespaces never remain in read/write mode during transportable tablespace operations.
- D. A transportable data pump import can leave a plugged-in tablespace in read/write mode.
- E. An ordinary data pump export of a table with encrypted columns will always encrypt the same columns when imported.
- F. A transportable data pump import can leave a plugged-in tablespace in read-only mode.
Answer: B,D,F
Explanation:
"This method for transporting tablespaces requires that you place the tablespaces to be transported in read-only mode until you complete the transporting process. If this is undesirable, you can use the transportable tablespaces from backup feature" -> BC correct MAX_DATAPUMP_JOBS_PER_PDB determines the maximum number of concurrent Oracle Data Pump jobs per PDB. -> D correct
