IBM SPSS Statistics Level 1 v2 — Question 31

Your job consists of a DB2 Connector stage followed by a Sort stage followed by a Transformer stage followed by another DB2 Connector stage.
The following two Balanced Optimizer options have been selected:
✑ Push processing to data sources
✑ Push processing to data targets
The following two Balanced Optimizer options have NOT been selected:
✑ Push data reduction processing to data targets
✑ Push all processing into the (target) data server
Assuming the job design allows for maximum optimization, what does the optimized job design look like?

Answer options

• A. Row Generator stage followed by a DB2 Connector stage
• B. DB2 Connector stage followed by a DB2 Connector stage
• C. DB2 stage followed by a Transformer stage followed by a DB2 Connector stage
• D. DB2 Connector stage followed by a Sort stage followed by a Transformer stage followed by another DB2 Connector stage

Correct answer: A

Explanation

The correct answer, A, indicates an optimized approach where the Row Generator stage can efficiently provide data to the DB2 Connector stage. The other options do not conform to the optimization strategy of pushing processing to data sources and targets, as they retain unnecessary stages that could lead to inefficiencies.
