I think Kinesis might complicate things more than help.

Isn't using ETL for Parquet a bit overkill for this?

Wait, why would you store files as large single objects?

I’m a bit confused about using Kinesis for batch processing; I thought it was more for real-time data. Is that really a good option here?

I practiced a similar question where using ETL to convert files to Parquet format was a recommended solution. It makes sense for performance.

Partitioning the data by date and region sounds familiar; I think it can significantly improve query efficiency in Athena.

I remember that reducing S3 object sizes can help with query performance, but I'm not sure if it should be less than 126 MB specifically.

This looks like a straightforward networking question. I think I'll go with option A - using Access Context Manager to create a secure perimeter and restrict access to the allowed IP ranges.

Okay, I've got this. The key is understanding what a "done increment of product" means. If the sprint is successful, it should result in a completed, usable piece of the final product. So the answer is B. True.

I'm a bit confused by the code snippet. I'll need to re-read it a few times to make sure I understand what's happening before I can confidently answer this.
