Mappings and Transformations
What happens to a row in a Router transformation that meets none of the user-defined group conditions?
It is dropped and an error is raised
It goes to the default group
It is sent to the first group
It is written to the reject file
B
A Router has a default output group that receives every row that matches no user-defined group. If you leave the default group unconnected, those rows are dropped silently. No error is raised, and rejects come from the writer or from an Update Strategy, not from the Router.

About this course

These practice tests are for ETL developers, data engineers, data quality specialists and career switchers preparing for Informatica job interviews and technical screenings. They are a quick way to find the gaps in your knowledge before the interview.

You get 6 practice tests with 103 to 104 questions each, 622 questions in total, including a timed Exam Mode test. Every question explains why the right answer is right and why the others are wrong, and each one is mapped to a topic area, from PowerCenter transformations, workflows and performance tuning to Informatica Data Quality, IDMC and real-time integration. The series was rebuilt for 2026: duplicates and questions on features that do not exist were removed, every answer key was re-checked, and explanations use current product names such as IDMC and note that PowerCenter 10.5 standard support ended in March 2026.
