x

Question

You are implementing a feature for Microsoft Dynamics 365 finance and operations apps implementation that requires handling events during the lifecycle of a business process.

You need to ensure that the application can respond to specific events without tightly coupling the event handlers to the business process logic.

What should you implement?

Select only one answer.

A. Create event handler classes and subscribe them to the appropriate delegates.
B. Use global variables to track the state of the business process and execute logic conditionally.
C. Implement a polling mechanism that checks for event conditions within the main process loop.
D. Embed the event response logic directly within the business process methods.

Answer

A. Create event handler classes and subscribe them to the appropriate delegates.

Explanation

Option A is correct because event handler classes and delegates provide a decoupled way to respond to events. Option B is incorrect as global variables do not provide a mechanism for event handling and can lead to tightly coupled code. Option C is incorrect because embedding the logic within the methods leads to tight coupling and is not a best practice for event handling. Option D is incorrect as polling is not an efficient or recommended method for event handling in this context.
