Discuss Databricks Databricks Certified Data Engineer Associate Exam Topic 1 Question 17

A Delta Live Table pipeline includes two datasets defined using STREAMING LIVE TABLE. Three datasets are defined against Delta Lake table sources using LIVE TABLE.

The table is configured to run in Development mode using the Continuous Pipeline Mode.

Assuming previously unprocessed data exists and all definitions are valid, what is the expected outcome after clicking Start to update the pipeline?

AAll datasets will be updated once and the pipeline will shut down. The compute resources will be terminated.

BAll datasets will be updated at set intervals until the pipeline is shut down. The compute resources will persist until the pipeline is shut down.

CAll datasets will be updated once and the pipeline will persist without any processing. The compute resources will persist but go unused.

DAll datasets will be updated once and the pipeline will shut down. The compute resources will persist to allow for additional testing.

EAll datasets will be updated at set intervals until the pipeline is shut down. The compute resources will persist to allow for additional testing.

Suggested Answer: E

I’m leaning towards E, sounds like a solid option for testing.

Moira 11 months ago

I disagree, C sounds wrong. Resources should be used continuously.

Christiane 11 months ago

Wait, so the compute resources just stay on? That seems odd.

Gerri 11 months ago

Definitely B! Makes the most sense for continuous mode.

Eva 11 months ago

I think the pipeline will keep running and updating at intervals.

Eileen 12 months ago

I feel like the datasets should update continuously until we manually stop the pipeline, which makes me lean towards option B.

Cordelia 12 months ago

I'm a bit confused about whether the compute resources will persist or not. I thought they would shut down after the updates.

Cora 12 months ago

I remember a practice question where the pipeline continued to run in Continuous Mode, so I feel like option E might be correct.

Adolph 1 year ago

I think the pipeline will keep running and update the datasets at intervals, but I'm not sure if it will persist the resources or shut them down.

Lonna 1 year ago

Hmm, I'm a bit confused about the compute resources part. Does that mean the pipeline will keep running and using resources even after the initial update? Or will it shut down and free up the resources? I need to re-read that part carefully.

Noble 1 year ago

I think the key here is the Continuous Pipeline Mode. That should mean the datasets will be updated repeatedly, not just a single time. And since the question mentions previously unprocessed data, I'm leaning towards option B or E.

Carmela 1 year ago

Okay, let me think this through. The pipeline is running in Continuous mode, so I'm guessing the datasets will be updated at set intervals rather than just once. But I'm not sure if the pipeline will shut down or persist after the initial update.

Ira 1 year ago

This question seems straightforward, but I want to make sure I understand the details about the pipeline configuration and how that affects the expected outcome.

Truman 1 year ago

Okay, I think I've got it. The pipeline is set to run continuously, so the datasets will be updated at regular intervals. And since it's in Development mode, the compute resources will persist even after the initial update, allowing for additional testing. I'm going with option E.

Tamar 1 year ago

Okay, let's see. The key things I need to focus on are the characteristics of the EPN, like how it's structured and what it's used for. I think if I can recall those core concepts, I should be able to pick the right answers.

Garry 1 year ago

Okay, let me think this through. The question is asking about an ISO/IEC 20000 requirement related to the service management plan. I think the key is to focus on the plan itself and what it must include, rather than other details. I'll go with B.

Nadine 1 year ago

Okay, let's see here... Continuous Pipeline Mode, huh? Sounds like a workout regime for data engineers. I'm sure the right answer is in here somewhere!

E) All datasets will be updated at set intervals until the pipeline is shut down. The compute resources will persist to allow for additional testing.

B) All datasets will be updated at set intervals until the pipeline is shut down. The compute resources will persist until the pipeline is shut down.

Pete 1 year ago

↳ replying to Nadine

A) All datasets will be updated once and the pipeline will shut down. The compute resources will be terminated.

Melodie 1 year ago

I'm going with option B. Seems like the most logical choice given the info provided. Though I do wonder if the compute resources will ever turn into self-aware AI and stage a rebellion. Just a random thought.

Lourdes 1 year ago

↳ replying to Melodie

I agree, option B seems like the most likely scenario based on the information provided. Let's hope the compute resources don't rebel!

Miles 1 year ago

↳ replying to Melodie

Haha, that's a funny thought about the compute resources becoming self-aware. But yeah, option B seems like the most logical outcome.

Malcom 1 year ago

↳ replying to Melodie

I think option B is the best choice here. It makes sense with the setup of the pipeline.

Therese 1 year ago

Wait, so the pipeline is in Development mode, but the data is 'previously unprocessed'? That's kind of a head-scratcher.

Walton 1 year ago

↳ replying to Therese

D) All datasets will be updated once and the pipeline will shut down. The compute resources will persist to allow for additional testing.

Aretha 1 year ago

↳ replying to Therese

It's a bit confusing, but I think it means the data will be updated periodically in Development mode.

Mitsue 1 year ago

↳ replying to Therese

B) All datasets will be updated at set intervals until the pipeline is shut down. The compute resources will persist until the pipeline is shut down.

Ling 1 year ago

Hmm, looks like a tricky one. I'll have to think this through carefully.

Omer 1 year ago

Hmm, that's interesting. I can see why you would think that. But I still think it's B because the compute resources will persist until the pipeline is shut down.

Jani 1 year ago

I disagree, I believe the answer is D. The datasets will be updated once and the pipeline will shut down.

Omer 1 year ago

I think the answer is B. The datasets will be updated at set intervals until the pipeline is shut down.

Vanna 2 years ago

Hmm, that's an interesting point. I can see why you think that. Let's wait and see what others think.

Ernest 2 years ago

I disagree, I believe the answer is D. The datasets will be updated once and the pipeline will shut down.

Vanna 2 years ago

I think the answer is B. The datasets will be updated at set intervals until the pipeline is shut down.
