MB-230 Extend Customer Service Practice Test 5 — 15 Questions

Question 1

You are extending Dynamics 365 Customer Service by creating a custom control using the Power Apps component framework (PCF). The control will be used on the Case form to display a timeline of customer interactions. You need to ensure the control can access data from the Case entity and update the form when a user selects an interaction. Which two actions must you perform? (Choose two.)

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Implement the updateView method to render the timeline based on the provided context.. To create a PCF control that displays a timeline of customer interactions on the Case form, you must implement the updateView method to render the timeline using the Case context. Additionally, you must use the Web API to retrieve related interaction records from a custom entity. These two actions enable the control to display data and update the form when an interaction is selected. Other options are either incorrect control types or insufficient for accessing related data.

Answer

Register the control as a dataset control and bind it to a view of interaction records.

Answer

Use the context.parameters property to access the Case entity fields directly.

Answer

Define the control as a field-level control in the form designer.

Question 2

You are a Dynamics 365 Customer Service consultant configuring a custom messaging channel. A JavaScript web resource on the Case form must call a custom API registered in the organization to retrieve the customer's preferred contact method from an external system. The web resource is loaded on the Case form in the Customer Service workspace. Which approach should you use to invoke the custom API from the JavaScript web resource?

Accepted Answer

Use Xrm.WebApi.online.execute to execute the custom API request. The supported and secure way to call a Custom API from a JavaScript web resource is Xrm.WebApi.online.execute. This method handles authentication, serialization, and error handling automatically, and it is the recommended approach for extending Customer Service forms. Other methods either bypass security, are deprecated, or introduce asynchronous complexity that is not suitable for synchronous form operations.

Answer

Use XMLHttpRequest to send a POST request to /api/data/v9.2/customapis(...)

Answer

Use a Power Automate flow triggered by a webhook and call it from JavaScript using fetch

Answer

Use the organization service endpoint via SOAP with a custom action

Question 3

You are configuring a custom channel in Omnichannel for Customer Service to handle inbound SMS messages. You need to ensure that the SMS channel can route conversations to the appropriate queue based on the customer's phone number. Which two actions must you perform? (Choose two.)

Accepted Answer

Add the SMS channel to a workstream and create a routing rule that checks if the customer's phone number exists in the Contact entity, then routes to a queue.. To route inbound SMS based on the customer's phone number, you must add the SMS channel to a workstream and create routing rules that evaluate the phone number against contact records. The workstream defines the channel and routing logic, while the routing rule uses the phone number to determine the queue. These two actions are essential and use native Omnichannel capabilities without custom development.

Answer

Configure the SMS channel's 'Phone Number' field in the channel settings to match the incoming messages to the correct queue.

Answer

Set up a Power Automate flow that triggers on incoming SMS and creates a case with the phone number as the customer identifier.

Answer

Enable the 'Phone Number Identification' setting in the Omnichannel administration app to automatically match incoming SMS to existing contacts.

Question 4

A customer service manager wants to add a custom button to the Case form that, when clicked, opens a new window with a pre-populated email to the customer. The button should be visible only to users with the 'Customer Service Manager' security role. What is the simplest way to achieve this?

Accepted Answer

Add a custom ribbon button using the Ribbon Workbench, configure its command to call a JavaScript function that opens the email, and set an enable rule based on the user's security role.. The simplest way to add a role-restricted button that opens a pre-populated email is to use the Ribbon Workbench to create a custom ribbon button. The button's command can call a JavaScript function that uses Xrm.Navigation.openUrl to open the default email client with pre-filled details. Enable rules can restrict visibility to users with the 'Customer Service Manager' security role, ensuring the button appears only for authorized users.

Answer

Create a Power Automate flow that sends an email when a case is updated, and add a button to the form that triggers the flow.

Answer

Use a Business Rule to show or hide a standard email field on the form and instruct users to click it to compose an email.

Answer

Create a JavaScript web resource that uses the Xrm.Navigation.openUrl method and add it to the form's OnLoad event.

Question 5

You are configuring a custom channel integration in Omnichannel for Customer Service. The channel uses a third-party messaging service that sends events via webhooks. You need to ensure that incoming messages create conversations in Omnichannel and are routed to the appropriate queue. What should you configure to receive the webhook events?

Accepted Answer

A webhook endpoint configured in the Omnichannel administration app for the custom channel.. To receive webhook events from a third-party messaging service and create Omnichannel conversations, you should configure a webhook endpoint in the Omnichannel administration app for the custom channel. This native feature handles the incoming events, authenticates them, and creates conversations that are routed to queues. Other options require custom development or do not provide the necessary integration with Omnichannel.

Answer

A custom connector in Power Apps that defines the webhook endpoint.

Answer

A Power Automate flow with an HTTP trigger.

Answer

An Azure Function with an HTTP trigger that calls the Omnichannel APIs.

Question 6

You are configuring a custom channel in Omnichannel for Customer Service. The channel must route incoming conversations to agents based on the customer's preferred language, which is stored in a custom field on the Contact entity. You have created a workstream and a routing rule set. Which component should you configure to ensure the language preference is evaluated during routing?

Accepted Answer

A custom routing rule with a condition that checks the Contact's preferred language field. To route based on a customer's preferred language stored on the Contact entity, you must create a custom routing rule that evaluates that field. Unified Routing supports conditions on related entities, so the rule can check the Contact's language field. This ensures the conversation is routed to the correct queue or agent based on the customer's preference.

Answer

A workstream queue that is assigned to agents with matching language skills

Answer

An agent skill rule that matches the language preference to the agent's skill score

Answer

A context variable that is populated from the Contact entity and used in a routing rule condition

Question 7

You are extending the Customer Service workspace by creating a custom session template that includes a Case form and a custom Power Apps component. You need to ensure that the component receives the case ID as a parameter when the session loads. Which method should you use to pass the case ID to the component?

Accepted Answer

Configure the component's input property to bind to the 'Case ID' field in the session template's context parameters.. Session templates in Customer Service workspace allow defining context parameters that hold record data, such as the case ID. Custom Power Apps components can have input properties bound to these parameters, enabling automatic data transfer when the session loads. This binding is the native, supported method for passing context to components, ensuring reliability and maintainability without custom code.

Answer

Use the component's 'OnLoad' event to query the current session context and extract the case ID from the global window object.

Answer

Write a JavaScript web resource that retrieves the case ID from the form and sets it on the component using the Xrm.Page API.

Answer

Create a Power Automate flow that passes the case ID to the component via a custom connector when the session opens.

Question 8

You are extending a Dynamics 365 Customer Service implementation by creating a custom entity that will store additional case-related data. You need to ensure that the custom entity can be used in Unified Routing to route cases based on its fields. Which configuration must you perform?

Accepted Answer

Create a relationship between the custom entity and the Case entity, and then add the custom entity's fields to the routing rule conditions.. Unified Routing evaluates conditions against the work item and its related entities. To route based on a custom entity's fields, you must create a relationship between that entity and the Case entity, then reference the related entity's fields in routing rule conditions. This allows the routing engine to access the data directly. Other options either invent non-existent settings or do not enable direct use in routing.

Answer

Register a plug-in on the Create message of the custom entity that updates the related case with the required data.

Answer

Enable the custom entity for Unified Routing by setting the 'Enable for routing' option in the entity configuration.

Answer

Add the custom entity to the Customer Service workspace app and enable it for Unified Interface.

Question 9

A Customer Service functional consultant is building a custom control for the Case form in Dynamics 365 Customer Service. The control must display a customer's open cases alongside real-time data from an external billing API, and it must be reused on both the Case form and the Account form without duplicating code. Which approach should the consultant use?

Accepted Answer

Create a PCF control using the Power Apps Component Framework and register it as a field-level component.. The Power Apps Component Framework is the only supported way to create reusable, code-based UI controls that can be placed on multiple forms and can call external services. A field-level PCF control can be bound to different fields on different forms, and it can use the browser's networking capabilities or connectors to fetch real-time data from an external billing API, satisfying both reuse and integration requirements.

Answer

Create a custom entity and add a subgrid to both forms to display the external data.

Answer

Build an HTML web resource and embed it in an IFRAME on both forms.

Answer

Write a JavaScript web resource and attach it to the OnLoad event of both forms.

Question 10

You are a functional consultant configuring a Microsoft Dynamics 365 Customer Service environment. Customer service representatives need to view a real-time dashboard on the Customer Service Hub that shows their own open cases and activities. The dashboard must be available to all representatives without modifying their security roles. What should you do?

Accepted Answer

Create a system dashboard and assign it to the Customer Service Representative role.. System dashboards are organization-owned and can be assigned to security roles, making them available to all users with that role. This approach satisfies the requirement to provide a dashboard to all representatives without altering their security role privileges. The dashboard can include views that filter records to the current user, showing their open cases and activities.

Answer

Create a Power BI dashboard and embed it in the Customer Service Hub.

Answer

Create a personal dashboard and share it with each representative.

Answer

Modify the default Customer Service Hub dashboard to include the required views.

Question 11

A customer service manager wants to add a custom button to the Case form that, when clicked, opens a custom HTML web resource in a modal dialog. The button should only be visible when the case status is 'Active'. Which approach should you use to implement this?

Accepted Answer

Add a ribbon button using the Ribbon Workbench and configure an enable rule that checks the status.. To add a custom button to the command bar that conditionally appears based on the case status, you should use the Ribbon Workbench. It allows you to define enable rules that can evaluate the form context, such as the status field, to show or hide the button. This is the recommended no-code/low-code approach for extending the command bar in Dynamics 365.

Answer

Use a business rule to show or hide a custom button added via the form designer.

Answer

Create a custom HTML web resource and embed it in the form, then use JavaScript to show or hide it based on status.

Answer

Add a button using a PCF control and bind it to the status field.

Question 12

You are extending Customer Service by creating a custom action that will be called from a JavaScript web resource on the Case form. The action must perform a complex validation involving multiple related entities and return a result to the JavaScript. Which approach should you use?

Accepted Answer

Create a JavaScript function that uses Xrm.WebApi to query related entities and perform the validation directly in the web resource.. For complex validation that must return a result to JavaScript, the best approach is to perform the validation directly in JavaScript using Xrm.WebApi to query related entities. This allows asynchronous data retrieval and logic execution, with the result available to the calling script. Custom actions and plug-ins are server-side and do not return synchronous results to client-side scripts, making them unsuitable for this requirement.

Answer

Create a synchronous plug-in registered on the Update message of the Case entity that performs the validation and throws an exception if invalid.

Answer

Create a custom action using the Dynamics 365 workflow designer and call it using the Xrm.WebApi.online.execute method.

Answer

Create a custom action using a plug-in registered on the custom action's message, and call it using the Xrm.WebApi.online.execute method.

Question 13

You are extending a Dynamics 365 Customer Service environment. The contact center director wants a custom web resource on the Case form to display a live status of the customer's order without storing order data in Dataverse. The web resource must call an external REST API that requires an API key. Where should you configure the API key so that the web resource can authenticate without exposing the secret to agents?

Accepted Answer

Store the API key in an environment variable and retrieve it via the Web API from the web resource.. Environment variables are the supported, secure way to store configuration data and secrets in Dynamics 365. A client-side web resource can retrieve the value through the Web API if the user has the appropriate read privileges on the environment variable definition and value. This avoids embedding secrets in code and keeps the integration maintainable across environments.

Answer

Create a Dataverse table named API Keys, store the key in a record, and retrieve it using the Web API.

Answer

Create a custom connector in Power Platform and reference it from the web resource.

Answer

Hard-code the API key in the JavaScript web resource and restrict the web resource to a specific security role.

Question 14

A customer service manager wants to add a custom button to the Case form that, when clicked, opens a custom HTML web resource in a modal dialog. The web resource must display data from the case record. Which method should you use to pass the case data to the web resource?

Accepted Answer

Use the Xrm.Navigation.openWebResource method and pass the case ID as a query string parameter.. Xrm.Navigation.openWebResource is the supported method to open a web resource in a modal dialog. By passing the case ID as a query string parameter, the web resource can retrieve the case data using the Web API. Other options use incorrect methods or unsupported techniques that do not integrate with the Dynamics 365 client API.

Answer

Use the Xrm.Utility.openWebResource method and pass the case data as a JSON string in the URL.

Answer

Use the window.open JavaScript function and pass the case ID in the window features parameter.

Answer

Use the Xrm.Navigation.openForm method to open the web resource as an entity form.

Question 15

You are a functional consultant for a company using Dynamics 365 Customer Service. The company wants to create a custom API that retrieves a customer's outstanding balance from an external ERP system and displays it on the Account form when an agent opens a case. The external system uses OAuth 2.0. You need to ensure the API can be called from a custom JavaScript web resource on the form. What should you use?

Accepted Answer

Use the XMLHttpRequest object in JavaScript to call the external API directly, including the OAuth token in the header.. The scenario requires calling an external REST API from JavaScript on a form. While best practice would be to use a server-side intermediary like an Azure Function or custom connector, among the given options, using XMLHttpRequest directly is the only method that can technically work from client-side JavaScript. However, this approach has security risks if tokens are exposed. The other options either do not support direct JavaScript invocation or are not designed for this purpose.

Answer

Register a custom API in the Dataverse and call it from JavaScript using XMLHttpRequest.

Answer

Create a Power Automate cloud flow and call it from JavaScript using the Microsoft Dataverse Web API.

Answer

Create a custom connector in Power Apps and call it from JavaScript using the Power Apps client API.
