Sample Free Questions

Domain : Extend the platform

Q1: You create a Custom API message. You need to develop a plug-in for your Custom API.

A. You need to know the message name
B. You need to register the plug-in for a step
C. After registration, you need to add the assembly to the solution
D. You need to know the names and types of the API parameters

Correct Answers: A, C and D


You can extend the Dataverse by creating the custom API that would be exposed as the messages. There are two types of custom messages: Custom Process Action and Custom API.

The Custom Process Actions messages are the no-code option that you can create using the Workflow Designer.

The Custom API provides the capabilities of code extending beyond the Workflow. You can use the maker portal, Web APIs, or the Organization service to create the Custom API. The Custom API data is saved in the Dataverse tables. You can invoke the custom message by using the Web API, Organization services, and plug-in.

Option A is correct because you need to know the message name, the names and properties of the message parameters, and the response properties for creating a plug-in for the custom message.
Option C is correct because after the assembly registration, by using the Dataverse Plug-in registration tools, you need to add the assembly to the solution.
Option D is correct because you need to know the message name, the names and properties of the message parameters, and the response properties for creating a plug-in for the custom message.
Option B is incorrect because you don’t need to register the step for the plug-in. You just need to register the plug-in’s assembly and add it to the solution.

Domain : Configure Microsoft Dataverse

Q2 : You need to create a new column in the custom Order table. The Dataverse table contains information about every order. The new column should store the number of days since the order record was created for the open (new) orders. The column should update the value whenever you save the record.
What should be the type of the new column?

A. Whole number
B. Rollup
C. Decimal number
D. Calculation
E. Duration

Correct Answer: D


Microsoft Dataverse provides special column types for calculations and data aggregation. These types are Calculated and Rollup.

The Calculation column allows users to define a formula based on the column value. This type includes columns from the same table and related parent table in a many-to-one relationship. Calculated columns are read-only. Users benefit from a list of built-in functions for the calculated values. This column type operates on the different data types like text, numeric, and date-time. The calculations run synchronously when a record is saved.

The Rollup column is like the Calculated type. The Rollup type operates only on the numeric (Whole Number, Decimal Number, and Currency) and date-time datatypes. This type includes columns from the same table and related child tables in a one-to-many relationship. The list of built-in functions for the Rollup column is smaller compared to the Calculated columns. It includes sum, min, max, and count. Rollup columns are read-only. By default, the calculations for the Rollup column run once per hour. Users can change the frequency in Customization settings for the table. It is an asynchronous operation.

Suppose you create the calculated column “DaysOpen.” Here is the condition and action for the column:Set Days Open Power Platform Calculation

The condition includes the check for the “New” order status. And the action has the Difference in days between the order date and a current date/time. If you use the NOW() function, you need to be sure that the date-time column’s behavior is set to the “User local” (in this case, the nwind_orderdate or “Order date” column (Number 1)). The “User local” behavior (Number 2) stores the time zone-aware data. This type of date-time behavior is the requirement for the NOW() operations.Tables order Power Platform

Options A, B, and D are incorrect because the Duration, Whole number, and Decimal number are the data types but not the column types.
