Acks=1 means immediate visibility, no doubt!

Wait, are you sure? I thought it needed to be replicated first.

Consumer will see the message right away with acks=1.

If I recall correctly, the consumer will only see the message when the high watermark advances, which means it’s option D.

I feel like the consumer should see the message immediately since the leader has acknowledged it, but I could be wrong about that.

I think I practiced a similar question where the consumer only sees the message after replication. So, maybe it's option D?

I remember that with acks=1, the message is considered sent once the leader acknowledges it, but I'm not sure if consumers can see it right away.

Whoa, this is a tricky one. I'm not totally sure about the conditions for the consumer seeing the message in this scenario. I'll have to review my Kafka concepts and try to work through the logic step-by-step.

Okay, I've got an idea. Since the message hasn't been replicated to the followers yet with acks=1, the consumer will only see it once the high watermark has advanced to include that message. I'm pretty confident that's the right answer.

Hmm, I'm a bit confused on this one. I know acks=1 means the message is only acknowledged after the leader receives it, but I'm not sure how that impacts the consumer seeing the message. I'll have to think it through carefully.

This one seems tricky, but I think I can work it out. Let me think through the acks=1 scenario and how that affects when the message is visible to the consumer.

I'm pretty confident the answer is B. The question states the data hasn't been replicated to followers yet, so the consumer wouldn't see the message until the replication is done.

Okay, let me think this through. The key here is that the producer used acks=1, so the data hasn't been replicated to the followers yet. I'm guessing the consumer would only see the message once the replication is complete, so I'll go with B.

Hmm, I'm a bit confused here. If the producer used acks=1, does that mean the message was only written to the leader and not the followers? I'm not sure if the consumer would see it right away or not.

This question seems straightforward, I think the answer is B since the producer used acks=1 so the message hasn't been fully replicated yet.

I feel pretty confident about this one. Based on my understanding of Dynamics 365 Supply Chain Management, the three objects that can be used to streamline the supply schedule form are transfer orders, scheduled Kanban, and production orders. I'll mark those and move on.

Option C is just silly. The produce request won't fail, it will simply wait for replication to complete.
