Which three statements are true about Transformer stages? (Choose three.)

  1. Derivations are written in C++.

  2. Constraints are executed before output link derivations.

  3. Stage variables are executed before output link derivations.

  4. @PARTNUM returns the number of job partitions currently active.

  5. Constraints can keep a record from being written to an output link.

B,C,E Correct answer
Explanation

Transformer stage execution order: Constraints filter first, then stage variables evaluate, then output link derivations run. This sequence matters because constraints can reject rows before stage variables or derivations execute, and stage variables are available to output derivations. Option A is false because derivations use DataStage BASIC, not C++. Option D is false because @PARTNUM returns the partition number, not count.
