NEW QUESTION 13
What are two benefits of applying a form pattern to a form? Each correct answer presents part of the solution.

• A. ensures data consistency by enforcing common relationship patterns between datasources
• B. provides default values for many properties on controls
• C. enforces a consistent style so that the forms a user encounters are immediately recognizable
• D. allows a developer to create many delivered forms from a base form

Answer: BC

Explanation: Section: Manage the User Interface and Security for Developers (20-25%) Explanation
Explanation/Reference:
Microsoft Dynamics 365 for Finance and Operations, Enterprise Edition, makes development easier by providing a guided experience for applying patterns to forms to ensure they are correct and consistent.
They help validate forms and control structures and the use of controls in certain places. Using patterns also ensures that each new form encountered by a user is immediately recognizable in appearance and function. Form patterns can provide many default control properties, which leads to a more guided development experience.

NEW QUESTION 14
You are working in a Microsoft Dynamics 365 for Finance and Operations environment that has an existing form named ModifyData and a display menu item named ModifyData1, which opens ModifyData. You create a second menu item named ModifyData2 that also opens ModifyData.
A privilege named ModifyData1View has the ModifyData1 menu item as an entry point with Read access.
There is also a privilege named ModifyData1Maintain that has the ModifyData1 menu item as an entry
point, with the Access Level property set to Delete. You create a new privilege named ModifyData2View
and add the ModifyData2 menu item as an entry point. You set the Access Level property to Read on the
ModifyData2 entry point.
You need to create a new duty named DataManager so that a role with this duty can delete data from
ModifyData when accessed through ModifyData1 and read data on the ModifyData form when accessed through ModifyData2.
What should you do to achieve this goal?

• A. Grant the ModifyData1Maintain privilege and the ModifyData2View privilege to the DataManager duty.
• B. Grant the ModifyData2View privilege to the DataManager duty.
• C. Grant the ModifyData1Maintain privilege to the DataManager duty.
• D. Grant the ModifyData1View privilege and the ModifyData2View privilege to the DataManager duty.
