In this lecture we walk through Sample Exam Question #4 from the Study Guide. This scenario deals with Roll-Up Summary fields between two custom objects. I cover the different possible answers and how they are either right or wrong. I also discuss how to strategically approach this question, first ruling out the obvious incorrect answers and then deciding between the remaining possible correct options.
I then create another sample production record, this time for a TV show, and then add a couple of episode records via the Master-Detail relationship field. I also create a roll-up summary field on the Production object to demonstrate the total number of episodes dynamically rolling up to the Production whenever new Episodes are added.
