Talend Exam Data-Integration-Developer Topic 4 Question 24 Discussion

Actual exam question for Talend's Data-Integration-Developer exam
Question #: 24
Topic #: 4
[All Data-Integration-Developer Questions]

You have a tMap component configured with a single input row1 and three outputs: CA, NY, Rejects. The input row1 consists of two columns. Name and State, containing the following data:

All outputs map only the Name column from row1, but CA employs a filter expression, CA.equals(row1.state), while Ny employs a filter expression, NY. Equals(row1, State). All Rejects have no such configuration.

Under these conditions, how does data flow to the outputs?

Show Suggested Answer Hide Answer
Suggested Answer: B

The tMap component allows you to configure multiple outputs for your data transformation and mapping. You can apply filter expressions on each output to filter out the rows that meet certain criteria. For example, if you want to send only the rows that have CA as the state value to one output, you can use CA.equals(row1.state) as the filter expression for that output. The filter expression evaluates to true or false for each row, and only the rows that evaluate to true are sent to the output. In this case, only Thomas Coolidge and Andrew Taylor have CA as their state value, so they are sent to the CA output. Similarly, only Calvin Adams has NY as his state value, so he is sent to the NY output. The Rejects output has no filter expression, so it receives all the rows from the input by default. However, since there is a conflict between the CA and NY outputs and the Rejects output, only the rows that are not sent to any other output are sent to the Rejects output. In this case, there are no such rows, so the Rejects output receives no data.Reference:Talend Open Studio: Open-source ETL and Free Data Integration | Talend,

D seems like the winner here. It's the only one that aligns with the stated conditions. Anything else would just be a mess, like trying to fit a square peg in a round hole. *laughs*

I'm not sure, but I think option D makes sense because it includes the correct names for each output.

I'm going with C. It's the only option that has the correct outputs for each stream - CA, NY, and Rejects.

I agree with you, Georgiann. The data flow to CA and NY outputs based on the filter expressions.

Option D makes the most sense to me. The CA output should get Thomas Coolidge and Andrew Taylor, the NY output should get Calvin Adams, and the Rejects output should get all three since they don't meet the filter criteria.
