Question #2 (Topic: demo questions)

You need to determine the primary cause of the issue reported by interns when they use the app. What is the primary cause?

A.

Interns have the System Customizer security role but need the Environment Maker security role.

B.

Interns have the Common Data Service User security role but need the Environment Maker security role.

C.

Interns have the Environment Maker security role but need the Common Data Service User security role.

D.

Interns have the Environment Maker security role but need the System Customizer security role.

E.

Interns have the Environment Maker security role but need the Delegate security role.

Correct Answer: D

Explanation:

Scenario: Interns can create apps but cannot interact with their own data. Environment Maker role: Can create new resources associated with an environment, including apps, connections, custom APIs, gateways, and flows using Microsoft Power Automate. However, this role doesn't have any privileges to access data within an environment. System Customizer role: full permission to customize the environment. However, users with this role can only view records for environment entities that they create.

Question #3 (Topic: demo questions)

You need to handle errors in UpdateRecord.js. Which code segment should you add at line UR06?

A.

catch(error) { alert("Caught error: " + error.message);}

B.

Exception exception = Server.GetLastError() ; if(exception != null)}

C.

catch(exception e){ console.writeline(e)}

D.

function (error){ console.log(error.message)}

Correct Answer: A

Explanation:


catch(error) {
    alert("Caught error: " + error.message);
}
Why A is correctUpdateRecord.js is a JavaScript file.

JavaScript uses the syntax 
JavaScript uses the syntax catch(error) to handle exceptions in a try...catch block.
error.message retrieves the error description.
alert() displays the error to the user.
Why the others are incorrectB ❌ Uses C#/ASP.NET syntax (Server.GetLastError()), not JavaScript.
C ❌ Uses incorrect Java/C#-style exception syntax and console.writeline is not a valid JavaScript method.
D ❌ function(error){ console.log(error.message) } is a callback function, not a catch block for exception handling.
✅ Answer: A.
catch(error) {
    alert("Caught error: " + error.message)

DRAG DROP

You need to address the user interface issues. What should you do? To answer, drag the appropriate actions to the correct issues. Each action may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

NOTE: Each correct selection is worth one point.

A.

Requirement Action
Resolve rendering issue for New and Save buttons. Add `&ribbondebug=true` to the end of the application URL.
Add email button for registration form. Use Ribbon Workbench.

Requirement	Action
Resolve rendering issue for New and Save buttons.	Add `&ribbondebug=true` to the end of the application URL.
Add email button for registration form.	Use Ribbon Workbench.

Correct Answer: A

Explanation:

Box 1: Add &ribbondebug=true to the end of the application URL. Scenario: The captions for the New and Save buttons do not render properly on the form. You can use the an in-app tool called the Command Checker to inspect the ribbon component definitions to help us determine why the button is not rendered correctly. To enable the Command Checker, you must append a parameter &ribbondebug=true to your D365 application URL. For example: https://yourorgname.crm.dynamics.com/main.aspx?appid=9ab590fc- d25e-ea11-a81d-000d3ac2b3e6&ribbondebug=true Box 2: Use the Ribbon Workbench Adding Buttons to Ribbons Download and install Ribbon Workbench. Select a suitable ICON for your button Create a solution. Edit the button in Ribbon Workbench. Publish and test.

DRAG DROP

You need to select connectors for the app. Which types of connectors should you use? To answer, drag the appropriate connectors to the correct requirements. Each connector may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

NOTE: Each correct selection is worth one point.

A.

Requirement Connectors
View full registration records. Create a custom connector.
View customer names. Use an AppSource connector.
View daily registrations. Use a native application function.

Requirement	Connectors
View full registration records.	Create a custom connector.
View customer names.	Use an AppSource connector.
View daily registrations.	Use a native application function.

Correct Answer: A

Explanation:

Box 1: Create a custom connector A custom connector is a wrapper around a REST API (Logic Apps also supports SOAP APIs) that allows Logic Apps, Power Automate, or Power Apps to communicate with that REST or SOAP API. Box 2: Use an AppSource connector You can only retrieve the Customer, UnifiedActivity, and Segments entities through the Power Apps connector. Other entities are shown because the underlying connector supports them through triggers in Power Automate. Scenario: Customer information is stored in the Accounts entity. Box 3: Use a native application function You must produce a report that details the number of registrations for a day and send the report as a PDF to the management team.

(Mapped Connectors & Options)
Requirement Mapped Connector Unused Options
