Practice Assessment for Exam MB-820: Microsoft Dynamics 365 Business Central Developer

Question 33 of 50

You are developing a custom API for a car dealership application using Microsoft Dynamics 365 Business Central. The application manages car brands and models, allowing users to create, read, update, and delete records.

You need to ensure the API supports deep insert operations to create a car brand with multiple car models in one request.

Each correct answer presents part of the solution. Which two actions should you take?

Defining a part on the API Car Brand page for API Car Model using the SystemId field in SubPageLink and setting the Multiplicity property to ZeroOrOne are both necessary actions to support deep insert operations. These configurations establish the required relationships and data handling capabilities. Disabling InsertAllowed, ModifyAllowed, and DeleteAllowed properties would prevent modifications, contradicting the goal. Setting ODataKeyFields to Name and Brand Id does not support deep inserts effectively, as it requires a single GUID field. Setting the ODataBaseUrl property to a custom endpoint does not facilitate deep insert operations, as it does not address the necessary data structure and relationships.

I am confused, why correct answer says setting the Multiplicity property to ZeroOrOne, if it is required to create a car brand with multiple car models in one request.
