Discuss Salesforce DEX-450 Exam Topic 12 Question 1

A developer working on a time management application wants to make total hours for each timecard available to application users. A timecard entry has a Master-Detail relationship to a timecard.

Which approach should the developer use to accomplish this declaratively?

AA Visualforce page that calculates the total number of hours for a timecard and displays it on the page

BA Roll-Up Summary field on the Timecard Object that calculates the total hours from timecard entries for that timecard

CA Process Builder process that updates a field on the timecard when a timecard entry is created

DAn Apex trigger that uses an Aggregate Query to calculate the hours for a given timecard and stores it in a custom field

Suggested Answer: B

Totally agree with B, it's the simplest solution!

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.

Definitely B, Roll-Up Summary is the way to go!

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.

Okay, let me break this down. A custodial arrest means the person is in police custody, right? And being read your rights is part of that process. So I'm going to go with A - True.

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.
