It's definitely A - Checkpointing and Write-ahead Logs!

I feel like replayable sources were mentioned in our notes, but I can't recall if they were part of the answer options we practiced.

I'm a bit confused about the role of idempotent sinks here. Do they really help with tracking offsets?

I think the answer might be A, since we practiced a similar question about fault tolerance in Structured Streaming.

I remember we discussed checkpointing in class, but I'm not entirely sure how it relates to write-ahead logs.

Option C about enabling termination protection doesn't seem relevant here. We want to delete the stack, just not the DynamoDB table. I'm leaning towards A or D as the best approaches.

This seems like a straightforward question about the benefits of mentoring. I'll focus on understanding the key aspects of mentoring and how they relate to the answer choices.
