Balanced optimizations are performed in a priority order. When there is ambiguity (for example, some processing could be performed either in a source or

Correct Answer: A

Balanced Optimization is a component of InfoSphere DataStage. It does not create parameter sets, change or optimize configurations, nor is there explicit mention of performing optimizations in priority order. The correct information is that Balanced Optimization is indeed installed with InfoSphere DataStage, making A the true statement.

Discussion

PozdaOption: B

The whole choice D is processing is pushed into database sources. But https://www.ibm.com/docs/en/iis/11.7?topic=optimization-job says to database target. Balanced Optimization is a licensed add-on to InfoSphere DataStage. Balanced Optimization does not change or optimize machine configurations, InfoSphere DataStage configurations, database configurations, or HDFS configurations. (https://www.ibm.com/docs/en/iis/11.3?topic=jobs-introduction-infosphere-datastage-balanced-optimization). Correct is B (https://www.ibm.com/docs/pl/iis/9.1?topic=optimization-big-data-file-stages)
