Answer :

Explanation:

Box 1: PreValidation -

PreValidation -

Pre-event/Pre-Validation -
This stage executes before anything else, even before basic validation if the triggering action is even allowed based on security. Therefore, it would be possible to trigger the plug-in code even without actually having permission to do so and great consideration must be used when writing a pre-validation plug-in. Also, execution in this stage might not be part of the database transaction.
Examples:- security checks being performed to verify the calling or logged on user has the correct permissions to perform the intended operation.
Note: Ideally, you should only cancel operations using synchronous plug-ins registered in the PreValidation stage. This stage usually occurs outside the main database transaction. Cancelling an operation before it reaches the transaction is highly desirable because the cancelled operation has to be rolled back.

Box 2: Synchronous -
When you throw an InvalidPluginExecutionException exception within a synchronous plug-in an error dialog with your message will be displayed to the user.

Box 3: Pre Image -


Box 4: Throw new InvalidPluginExecutionException("Your error message", ex);
When you throw an InvalidPluginExecutionException exception within a synchronous plug-in an error dialog with your message will be displayed to the user.

Background -
Adventure Works Cycles wants to replace their paper-based bicycle manufacturing business with an efficient paperless solution. They have one manufacturing plant in Seattle that produces bicycle parts, assembles bicycles, and distributes finished bicycles to the Pacific Northwest.
Adventure Works Cycles has a retail location that performs bicycle repair and warranty repair works. They also have six maintenance vans that repair bicycles at various events and residences.
Adventure Works Cycles recently deployed Dynamics 365 Unified Operations in a Microsoft-hosted environment for financials and manufacturing. They plan to leverage the Microsoft Power Platform to migrate all of their distribution and retail workloads to Dynamics 365 Unified Operations.
They use Dynamics 365 Customer Engagement for all customer activities, including field service.
Current environment. Retail store information
Adventure Works Cycles has one legal entity, four warehouses, and six field service technicians.
Warehouse counting is performed manually by using a counting journal. All warehouse boxes and items are barcoded.
The Adventure Works Cycles retail location performs bicycle inspections and performance tune-ups. Technicians use paper forms to document the bicycle

inspection performed before a tune-up and any additional work performed on the bicycle.
Adventure Works Cycles uses a PowerApps app for local bike fairs to attract new customers.
A canvas app is being developed to capture customer information when customer check in at the retail location. The app has the following features:
- Customer selects yes or no if they are on the mailing list.
- Customer select the amount of times they have visited the store.
- Customer select the type of service needed.
- The search result returns all last name records that match the search term.

Current environment. Technology -
A plug-in for Dynamics 365 Sales automatically calculates the total billed time from all activities on a particular customer account, including sales representatives visits, phone calls, email correspondence, and repair time compared with hours spent.
A shipping API displays shipping rates and tracking information on sales orders. The contract allows for 3,000 calls per month.
Ecommerce orders are processed in batch daily by using a manual import of sales orders in Dynamics 365 Unified Operations.
Microsoft Teams is used for all collaboration.
All testing and problem diagnostics are performed in a copy of the production environment.
Customer satisfaction surveys are recorded with Microsoft Forms Pro. Survey replies from customers are sent to a generic mailbox.

Requirements. Automation -
A text message must be automatically sent to a customer to confirm an appointment and to notify when a technician is on route that includes their location.
Ecommerce sales orders need to automatically integrate into Dynamics 365 Unified Operations.
A text alert must be sent to employees scheduled to assist in the repair area of the retail store if the number of repair check-ins exceeds eight.
Submitted customer surveys must generate an email to the correct department. Approval and follow-up must occur within a week.

Requirements. Reporting -
The warehouse manager"™s dashboard must contain warehouse counting variance information.
A warehouse manager needs to quickly view warehouse KPIs by using a mobile device.
Power BI must be used for reporting across the organization.

Requirements. User experience -
Warehouse counting must be performed by using a mobile app that scans barcodes on boxes.
All customer repairs must be tracked in the system no matter where they occur.
Qualified leads must be collected from local bike fairs.

A developer must register a step using the Plug-in registration tool.
You need to associate the correct Event Pipeline Stage of Execution with its purpose.
Which stage should you associate with each description? To answer, drag the appropriate stages to the correct descriptions. Each stage 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:




Answer :

Explanation:
The event pipeline allows you to configure when in the event the plug-in code will execute. The event pipeline is divided into the following events and stages:

Box 1: PreValidation -

Pre-event/Pre-Validation -
This stage executes before anything else, even before basic validation if the triggering action is even allowed based on security. Therefore, it would be possible to trigger the plug-in code even without actually having permission to do so and great consideration must be used when writing a pre-validation plug-in. Also, execution in this stage might not be part of the database transaction.
Examples:- security checks being performed to verify the calling or logged on user has the correct permissions to perform the intended operation.

Box 2: PreOperation -

Pre-event/Pre-Operation -
This stage executes after validation, but before the changes has been committed to database. This is one of the most commonly used stages.
Example uses:
If and "update" plug-in should update the same record, it is best practice to use the pre-operation stage and modify the properties. That way the plug-in update is done within same DB transaction without needing additional web service update call.

Box 3: PostOperation -
Plug-ins which are to execute after the main operation. Plug-ins registered in this stage are executed within the database transaction.
This stage executed after changes have been committed to database. This is one of the most used stages.
Example uses:
Most of the "Create" plugins are post-event. This allows access to the created GUID and creation of relationships to newly created record.
Incorrect Answers:
MainOperation:- main operation of the system, such as create, update, delete, and so on. No custom plug-ins can be registered in this stage.

HOTSPOT -
A company imports data from files.
The following code is created to import the files. (Line numbers are included for reference only.)


For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:



Answer :

Explanation:

Box 1: No -
Need to set ContinueOnError=True. ContinueOnError: When true, continue processing the next request in the collection even if a fault has been returned from processing the current request in the collection. When false, do not continue processing the next request.

Box 2: No -
ContinueOnError = true must be added before Requests = new OrganizationRequestCollection() on line 3.
Example:
// Create an ExecuteMultipleRequest object.
requestWithResults = new ExecuteMultipleRequest()
{
// Assign settings that define execution behavior: continue on error, return responses.
Settings = new ExecuteMultipleSettings()
{
ContinueOnError = false,

ReturnResponses = true -
},
// Create an empty organization request collection.
Requests = new OrganizationRequestCollection()
};

Box 3: Yes -
You can use the ExecuteMultipleRequest message to support higher throughput bulk message passing scenarios in Common Data Service.
ExecuteMultipleRequest accepts an input collection of message Requests, executes each of the message requests in the order they appear in the input collection, and optionally returns a collection of Responses containing each message"™s response or the error that occurred.

Box 4: No -
This is just for displaying the result.

Solution:
Enable change tracking for entities that will be synchronized.
Use the Data Export Service to sync data between the database and Dynamics 365 Sales.
Does the solution meet the goal?

  • A. Yes
  • B. No


Answer : A

Explanation:
Large organizations that synchronize their data with external data sources can now enable entities for change tracking. You can export or retrieve a selected set of data, and then keep the external data warehouse in sync.
The Data Export Service is an add-on service made available on Microsoft AppSource that adds the ability to replicate data from Common Data Service database to an Azure SQL Database store in a customer-owned Azure subscription.
The Data Export Service intelligently synchronizes the entire data initially and thereafter synchronizes on a continuous basis as changes occur (delta changes) in the system.
You can use the Data Export Service with model-driven apps in Dynamics 365, such as Dynamics 365 Sales and Dynamics 365 Customer Service.
