Question 5

Your job aggregates data before writing the results out to a DB2 table. You have since learned that this job will be required to aggregate very large amounts of data. To ensure high performance you create a new, non-default configuration file for the job that defines a node pool named “highperfnodes” that includes only nodes with very high processing power.

What additional design changes do you need to make to the job to ensure that it aggregates the data using the “highperfnodes” pool? (Choose two.)
