I vaguely remember a question about Static Entities. The example used a record type named Book, and it was related to an employee over the course of one year. But I’m not sure about the details.
.....In the certification exam
This is a strange question... each exam has different questions. We are not getting all the same questions.
I don't understand why you keep dropping questions, instead of studying all available training material and documentation. It should not be hard to find the answer yourself.
