Question 1 of 61

HOTSPOT -

A company is building a new model-driven app.

The app must integrate with a number of on-premises and cloud solutions. No VPNs are in place.

You need to determine the method for each integration.

Which methods should you use? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Hot Area:

    Correct Answer:

    Box 1: Webhook -

    With Common Data Service, you can send data about events that occur on the server to a web application using webhooks. Webhooks is a lightweight HTTP pattern for connecting Web APIs and services with a publish/subscribe model.

    Box 2: Azure Event Hub -

    Azure Event Hubs is a big data pipeline. It facilitates the capture, retention, and replay of telemetry and event stream data. The data can come from many concurrent sources.

    It has the following characteristics:

    ✑ low latency

    ✑ capable of receiving and processing millions of events per second

    ✑ at least once delivery

    Box 3: Plugin -

Question 2 of 61

DRAG DROP -

You need to select the appropriate methods using the Azure Event Grid.

Which method should you use for each requirement? To answer, drag the appropriate methods to the correct requirements. Each method 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.

Select and Place:

    Correct Answer:

    Box 1: Event handler -

    Event handlers - The app or service reacting to the event.

    Box 2: Event subscriptions -

    Event subscriptions - The endpoint or built-in mechanism to route events, sometimes to more than one handler. Subscriptions are also used by handlers to intelligently filter incoming events.

    Note:

    There are five concepts in Azure Event Grid that let you get going:

    Events - What happened.

    Event sources - Where the event took place.

    Topics - The endpoint where publishers send events.

    Event subscriptions - The endpoint or built-in mechanism to route events, sometimes to more than one handler. Subscriptions are also used by handlers to intelligently filter incoming events.

    Event handlers - The app or service reacting to the event.

Question 3 of 61

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

A Common Data Service (CDS) environment has two custom entities named Building code and Work item. Building code has a code date custom field and Work item has an elapsed time custom field. Construction workers use a consolidated custom form with data from both entities to fill.in their daily work items.

A JavaScript library is used with these custom entities and fields to apply complex logic.

You need to ensure that the JavaScript library continues to function as originally designed if other developers expand the environment.

Solution: In form properties of the consolidated form, add the JavaScript library in the events tab and add the two custom fields to the dependent fields section of the non-event dependencies tab.

Does the solution meet the goal?

    Correct Answer: B

    In the form properties of the consolidated form, adding the JavaScript library in the events tab is a valid step. However, adding the two custom fields to the dependent fields section of the non-event dependencies tab is not sufficient to ensure the JavaScript library will function as designed if other developers expand the environment. The non-event dependencies tab is used to specify dependencies for the form itself, not the fields used in the JavaScript. Instead, it is necessary to specify dependencies directly within the JavaScript library to ensure it continues to function correctly by linking the Building code with the Code date and the Work item with the Elapsed time field directly in the JavaScript dependencies.

Solution: In the JavaScript library, add Building code with Code date and Work item with Elapsed time in the dependencies tab.

Does the solution meet the goal?

    Correct Answer: A

    A

    Within a solution you can define dependencies within solution components. Up until Dynamics 365 for Customer Engagement apps version 9.0 the main purpose of these dependencies was to prevent the deletion of a solution component when another solution component depended on it.

    The following image shows the dependencies tab within the web resource form. Dependencies between web resources are set in the top list.

Question 5 of 61

You have the following code:

You have a contact record that uses the GUID 2CFB1599-DEAD-425F-AB4A-76E6CAB51B09.

You need to assign the contact record as the primary contact for an account when you create the account.

Which two code segments can you use? Each correct answer presents a complete solution.

NOTE: Each correct selection is worth one point.

A.

B.

C.

D.

    Correct Answer:

    To assign the contact record as the primary contact for an account when creating the account, you can use the following two code segments: B and C. Both segments correctly structure the `primarycontactid` field necessary for the Web API request. Option B uses the format where the logicalname and id of the contact are specified separately, which is one correct method. Option C uses the @odata.bind annotation to bind the contact entity to the account, which is another correct method. The other options do not follow the correct syntax for creating such relationships in the API request.
