Nope, it definitely needs a Refresh Data node to trigger.

Wait, so it doesn't run when the screen initializes? That's surprising!

I thought it would run automatically at start, but I guess not.

I practiced a question similar to this, and I think it was about how Aggregates run on demand, so I might go with C as well.

I'm not entirely sure, but I feel like Aggregates with that setting might only run when explicitly called, which makes me think of option B.

I remember something about Refresh Data nodes being used to trigger Aggregates, so maybe C is the right choice?

I think the Fetch property set to Only On Demand means it won't run automatically, so I’m leaning towards option B or C.

I've got this one! The key is that "Only On Demand" means the Aggregate won't run automatically. So it has to be triggered manually, either through a Server Action or a Refresh Data node. Option C is the way to go.

Okay, let me think this through. If the Aggregate is set to "Only On Demand", that means it won't run automatically like the "At Start" option. So it would need to be triggered programmatically, either through a Server Action or a Refresh Data node in a Screen Action. I think option C is the correct answer.

Hmm, I'm a bit confused about the difference between "At Start" and "Only On Demand" for Aggregates. I'll need to review that part of the material again to make sure I understand it.

I'm pretty sure this has to do with how the Aggregate is configured to run. If it's set to "Only On Demand", then it should only run when explicitly triggered, not automatically.

Easy peasy! The purpose of a Sprint is to deliver a finished, working piece of the product. So the answer is definitely True.

Haha, this question is a real brain-teaser! I'm going to go with B, but I'm not 100% confident. Maybe I should have paid more attention in that last training session.
