I think increasing the timeout could actually slow things down.

Surprised that increasing memory isn't mentioned more often!

Decreasing the timeout? That sounds counterproductive.

Totally agree, more shards = better parallel processing!

Increasing the number of shards can help with throughput.

I wonder if decreasing the timeout would actually make things worse; I think we want to give the function enough time to process records.

I practiced a similar question, and I feel like increasing the timeout wouldn't really help with processing speed.

I'm not entirely sure, but I remember something about increasing memory for Lambda functions can improve performance.

I think increasing the number of shards could help since it might allow for more parallel processing of records.

I wonder if increasing the timeout could be beneficial, but I’m not confident about that. I definitely think we need to look at the shards though.

I practiced a similar question, and I think decreasing the timeout isn't the right move here. It seems counterintuitive to limit processing time when it's already slow.

I'm not entirely sure, but I feel like increasing the memory for the Lambda function could also help with performance. Maybe option C?

I remember reading that increasing the number of shards can help with processing speed, so I think option A might be a good choice.

Okay, I think I've got this. The correct answer is A - customers need to balance all those different areas, not just focus on IT or outsource their marketing. Gotta keep the whole business running smoothly.

I'm a little confused by the wording of the question. I'll need to re-read it a few times to make sure I understand what they're asking for.

Wait, I'm a bit confused. Is it Primary Activities and Support Activities? Or is it Operational Activities and Marketing and Sales Activities? I better double-check my understanding before answering.
