APICS Certified Supply Chain Professional (CSCP) — Question 504

You are a Dynamics 365 Finance developer.

You need to create an extension class.

Which action should you perform?

Answer options

• A. Mark the class as public.
• B. Decorate the class with the ExtensionOf attribute.
• C. Mark the class as private.
• D. Add the suffix .extension to the file name.

Correct answer: B

Explanation

The correct answer is B because decorating the class with the ExtensionOf attribute is essential for defining it as an extension class in Dynamics 365 Finance. Options A and C are incorrect as they pertain to class visibility rather than extension functionality, and option D is not a requirement for creating extension classes.
