I thought ACK meant closed too?

A closed port shows no return response.

I feel like ACK is more about established connections, so it might not be the right answer here.

I remember something about RST packets indicating a closed port from our practice questions.

I think a closed port might show no return response, but I'm not entirely sure.

I keep mixing up SYN and RST responses; I hope I can remember which one indicates a closed port during the exam!

Hmm, I'm not entirely sure about this one. I'll have to think it through step-by-step to figure out the right answer.

I keep mixing up `tx.origin` and `msg.sender`. I wish I had gone over more examples before the exam!

I'm feeling pretty confident about this one. The data scientist needs to remove the stopwords from the blog post data, but keep the rare words that are relevant. Option D, using the Count Vectorizer function, seems like the most straightforward way to do that. I'll double-check the other options, but I think that's the way to go.

I feel confident that C applies because we discussed how Auto Scaling replaces unhealthy instances automatically, so that seems relevant.

This seems like a straightforward question about identifying the right approach to highlight the required changes. I think I'll start by describing the current state and then explore how to model the new organizational structure.
