Not sure about this, can someone explain why B is better?

Wait, why would you use a table for Product? Seems off.

I feel like option B might be right, but I'm confused about whether customers should be streams or tables.

I practiced a similar question, and I think having customers as streams makes sense because they can change over time.

I'm not entirely sure, but I think products should be modeled as tables since they have a fixed set of attributes.

I remember we discussed that purchases are usually events, so they might be better as a stream.

Ah, I remember this from the lecture! I'm pretty sure the answer has to do with the board type, but I can't recall the specifics. Gotta focus and think this through.

Okay, I think the key here is to look for any faults or health issues related to the EPG. That might give me a clue as to what happened and who was involved.

I'm feeling pretty confident about this one. The file blocking profile is definitely the way to go to prevent users from downloading malicious files, rather than just blocking all web access.

This looks like a straightforward question about IP filters on the Nokia 7750 SR. I should be able to handle this.

I'll take 'Things I Don't Want to See in My Kafka Cluster' for 500, Alex. A purchase stream? What is this, Black Friday at Walmart?

Option C is the only one that makes sense to me. I mean, who wants to be on the receiving end of a 'purchase stream'? Sounds like a recipe for a data firehose.

I was totally going to choose option A, but then I realized that's just way too many streams. Maybe if we had a really complex use case, but for a simple ecommerce site, that seems overkill.

I see your point, Lemuel. Having Purchase as stream and Product as table could provide more flexibility and scalability in the long run.

Option D seems interesting, but I'm not sure why we'd want the customer to be a stream. Wouldn't that make it harder to look up customer information?

I think option B is the most natural way to model this data. Purchases are events, but products and customers are more like tables that we need to look up.

That's true, it provides a good balance between real-time processing and the ability to look up historical data.
