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

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?

ACA:Thomas Coolidge Andrew TyalorlNY;Calvin Adams;rejects;none

BCA:Thomas Coodge;Calvin Adams; rejects:Andrew Taylor

CCA:Thomas Coolidge;Ny:Calvin Adams;rejects:Thomas Coolidge, adrew taylor, Calvin Adame

DCA:Thomas Coolidge, Andrew Taylor;Ny:Calvin Adams; rejects:Thomas Coolidge, Andrew Taylor,Calvin Adams

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,

I think D is the right answer, looks accurate!

Sabine 11 months ago

Rejects should have all the others, right?

Arlene 11 months ago

Wait, how does NY get Calvin Adams? Seems off.

Renay 11 months ago

Totally agree, CA is spot on!

Peggy 12 months ago

CA filter only lets through Thomas Coolidge and Andrew Taylor.

Bettye 12 months ago

I practiced a question like this, and I think the answer might be D, but I’m not entirely sure about how the filters work together.

Jacquline 12 months ago

I feel like the Rejects should include all names that don't match CA or NY, but I can't recall the exact logic we used in class.

Gussie 1 year ago

I think CA should only have Thomas Coolidge based on the filter, but I'm not completely confident about the Rejects output.

Cassie 1 year ago

I remember practicing similar questions about filtering in tMap, but I'm not sure if CA should include both names or just one.

Wilburn 1 year ago

I feel pretty confident about this one. The key is understanding how the filter expressions work and applying that to the given input data. I think I can nail this question.

Lashanda 1 year ago

Whoa, this is a lot of information to process. I'm a bit confused about how the different filter expressions are going to impact the data flow. I'll need to re-read this a few times.

Willie 1 year ago

Okay, let me break this down step-by-step. The input data, the filter conditions for each output - I think if I work through it methodically, I can figure this out.

Carlene 1 year ago

Hmm, this looks like a tricky one. I'll need to carefully read through the details and think through the logic of the filter expressions.

Caitlin 1 year ago

I've got a strategy for this. I'll start by mapping out the input data and the filter conditions for each output. Then I'll walk through the logic to determine which names end up where.

Cathern 1 year ago

Okay, I've got this. Withdrawal is when you experience negative sympShawnee from stopping a medication abruptly. That's the key thing this question is asking about. I'm confident C is the right answer.

Merlyn 1 year ago

Okay, I've got this. The remote acceptance functions are PPPOE simulation test, DHCP simulation test, Voice call simulation test, and BTV simulation test. I'll select all of those.

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*

It's like trying to fit a square peg in a round hole with the other options.

↳ replying to Denise

Agreed, D is the most logical choice.

Yeah, D is the only one that follows the conditions.

I think D is the correct answer.

Nancey 2 years ago

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

Tijuana 2 years ago

Option D all the way! Gotta love those tMap components and their fancy filters. *chuckles*

Lavonna 2 years ago

Hmm, this is a tricky one. I'm going to have to go with D. It just seems the most logical based on the information provided.

Sharen 2 years ago

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

Salina 2 years ago

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

Nicolette 2 years ago

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.

Allene 2 years ago

↳ replying to Nicolette

Yes, Option D is the right choice. It clearly defines how the data will flow to each output based on the filter conditions.

Laurena 2 years ago

↳ replying to Nicolette

I agree with you. Option D seems to be the correct configuration based on the filter expressions for CA, NY, and Rejects.

I think the correct answer is D.
