문제1
You have a parallel job that does not scale beyond two nodes. After investigation you find that the data has been partitioned on a DoNotCall flag, which has only "Y" or "N" values, and you have an Aggregator stage that is accumulating totals based on this flag using a sort method. Which two techniques could you use to allow the job to scale? (Choose two.)

A parallel job combines rows from a source DB2 table with historical information maintained in two separate Oracle tables. Only rows in the DB2 source whose key values match either Oracle table are output to a target Teradata table. Both Oracle tables have identical column definitions and are stored in the same Oracle instance. Which two design techniques would satisfy this requirement? (Choose two.)
