You have multiple transformations that read and process data from multiple text files. You identity a series of steps that are common across transformations and you want to re-use them to avoid duplication of code.
How do you accomplish this?

I thought D was the right choice, but now I'm confused.

A is the way to go, no doubt about it!

Wait, can you really use option C for this? Seems off.

I think B sounds interesting, but I'm not sure it fits here.

Definitely go with option A, it's the best way to reuse steps!

I vaguely recall something about the Job Executor step, but I can't remember if it was for reusing code or something else. It feels a bit off to me.

I think we practiced a similar question where we had to reuse steps, and I chose a mapping step then too. That makes me lean towards A again.

I'm not entirely sure, but I feel like the ETL Metadata Infection step was mentioned in a different context. It doesn't seem to fit here.

I remember we talked about using sub-transformations to avoid code duplication, so I think option A might be the right choice.

The 'Job Executor1' step doesn't ring a bell for me. I'll have to do some research on that one to see if it could be a viable solution.

Using the 'Get data from XML' step doesn't seem relevant to this problem. I think that's more for reading data from XML sources, not reusing common processing steps.

The 'ETL Metadata Infection' step sounds interesting, but I'm not sure if that's the right approach here. I'll need to double-check the details on that one.

This looks like a common problem in data processing. I think the 'Mapping (sub-transformation)' step would be the best way to reuse the common series of steps across multiple transformations.

Hmm, I'm not too familiar with the 'Mapping (sub-transformation)' step. I'll have to look into that option more closely. Hopefully, the exam provides some examples or guidance on how to use it.

Okay, I think the Platform Administration Guide is the best bet here. That guide would likely include information on the platform architecture and recommendations. I'll go with that choice.

I'm pretty sure the correct answer is B - a member of staff losing a laptop. That's a clear security incident that could lead to a data breach or other security problems. The other options don't seem to be directly related to security.

Mapping step all the way! It's the only option that makes sense. The other choices are like trying to put a square peg in a round hole.

Job Executor1? Sounds like something out of a sci-fi movie. I'll pass on that and choose the Mapping step instead.

The Mapping step seems like the most efficient way to handle common steps across transformations.

Job Executor1 does sound like something from a sci-fi movie, I'll stick with the Mapping step.

I agree, the Mapping step is a better choice for re-using common steps.

Get data from XML? Seriously? This is a text file processing question, not an XML one. I'm going with the Mapping step.

ETL Metadata Infection? What is that, some kind of disease? I'll stick with the Mapping step, thank you very much.

The 'Mapping (sub-transformation)' step is the way to go. It's a great way to encapsulate common functionality and reuse it across multiple transformations.
LI

That's a good point. It definitely helps with code reusability.

A) Use the 'Mapping (sub-transformation)' step containing the series of steps.

I'm not sure, but I think option B) could also work. Using ETL Metadata Injection might be a good solution.

I agree with Rebecka. Option A) seems like the most efficient way to re-use common steps.
RE

I think option A) is the best choice. Using a sub-transformation can help avoid code duplication.
