Wait, can a Roll-Up Summary even handle that many entries?

A Visualforce page? Seems like overkill for this.

I think C could work too, but it's not as efficient.

I recall that Apex triggers are usually for more complex logic, so I don't think that's the best option here.

I practiced a similar question where we had to calculate totals, and I feel like a Visualforce page is more complex than necessary for this.

I'm not entirely sure, but I remember something about using Process Builder for updates. Would that work for this scenario?

I think a Roll-Up Summary field might be the right choice here since it automatically calculates totals for related records.

The ADM Guidelines and Techniques seem like a good place to look for information on categorizing architecture outputs, so I'll go with A.

This one seems pretty straightforward. I'm pretty sure the IP layer is known for providing a connectionless data transmission service, so I'll go with option A.

Wait, do I need to do anything to the actual data on the worksheet before applying the chart and colors? I want to make sure I'm not missing a step here.
