Databricks Certified Data Engineer Associate Exam - Topic 1 Question 3 Discussion

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 Production 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?
E) All datasets will be updated once and the pipeline will shut down. The compute resources will persist to allow for additional testing.
A) 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 once and the pipeline will persist without any processing. The compute resources will persist but go unused.
C) All datasets will be updated at set intervals until the pipeline is shut down. The compute resources will be deployed for the update and terminated when the pipeline is stopped.
D) All datasets will be updated once and the pipeline will shut down. The compute resources will be terminated.

Isn't it weird that they would just terminate after one update?

I disagree, I feel like they should persist for testing.

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

Definitely going with option D! Makes the most sense.

I think all datasets will update once and then shut down.

I feel like the pipeline should keep running and updating the datasets until we manually stop it, which makes me lean towards option C.

I'm a bit confused about the difference between streaming and live tables. I feel like they might update differently, but I can't recall the specifics.

I think I practiced a question similar to this, and it mentioned that the compute resources would persist. So maybe it's option A?

I remember that in Continuous Pipeline Mode, the datasets should keep updating, but I'm not sure if they stop after one update or keep going.

Ugh, I'm not sure about this one. The options seem similar, and I'm a bit confused on the differences between the services. Guess I'll have to make an educated guess.

Okay, let me think this through. The question is asking about the required communications, so I'll need to focus on the key requirements rather than optional or additional communications. I think I can eliminate a few of these options.
