HOTSPOT (Drag and Drop is not supported)
You need to package and deploy a Power Apps code component to an environment.
Which commands should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:


Box 1: pac solution init --publisher-name
Create a new solutions project using the following command. The solution project is used for bundling the code component into a solution zip file that is used for importing into Dataverse. pac solution init --publisher-name developer --publisher-prefix de

Box 2: pacauth create
Connecting to your environment.
Auth commands are used to authenticate to Dataverse.
Creates the authentication profile for your organization by passing the url parameter. Shows AAD dialog if sign in credentials are not specified.
Example: pacauth create --url https://Myorg.crm.dynamics.com
Box 3: pacpcf push --publisher-prefix

Deploying code components
After you have successfully created an authentication profile, you can start pushing the code components to the Dataverse instance with all the latest changes.
The push capability speeds up the inner-developer cycle development because it bypasses the code component versioning requirements and does not require that you build your solution (cdsproj) to import the code component.

To use the push capability, do the following:
1. Ensure that you have a valid authentication profile created.
2. Navigate to the directory where the sample component file is located.
3. Run the command.
pacpcf push --publisher-prefix <your publisher prefix>
Incorrect:
Commands for working with Dataverse solution projects include:

Parameter init
Initializes the solution project. It has the following parameters: publisher-name: Publisher name of the organization. publisher-prefix: Publisher prefix of the organization.

HOTSPOT (Drag and Drop is not supported)
An online store has a custom web page that allows customers to place their orders against a Microsoft Dataverse database that uses custom products. The custom web page uses Web API patterns to create and update records.
Customers report that orders can be placed for out-of-stock items.
You need to update the page code to ensure that inventory is available before confirming an order.
Which pattern should you use for each step? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:


Box 1: IsOptimisticConcurrencyEnabled
On a multi-threaded and multi-user system like Power Apps, operations and data changes often happen in parallel. A problem arises when two or more update or delete operations on the same piece of data happen at the same time. This situation could potentially result in data loss. The optimistic concurrency feature provides the ability for your applications to detect whether a table record has changed on the server in the time between when your application retrieved the record and when it tries to update or delete that record.

Box 2: If-Match: Etag
Use If-Match and If-None-Match headers with ETag values to check whether the current version of a resource matches the one last retrieved, matches any previous version or matches no version. These comparisons form the basis of conditional operation support. Dataverse provides ETags to support conditional retrievals, optimistic concurrency, and limited upsert operations.

A company is creating a one-way integration from Microsoft Dataverse to an external system. Data will be sent from a webhook to an Azure Function.
You need to configure the Azure Function to handle data from the webhook.
Which class and data type must the Azure Function handle?

  1. RemoteExecutionContext in .NET binary format
  2. RemoteExecutionContext in JSON format
  3. RemoteExecutionContext in XML format
  4. IPluginExecutionContext in JSON format
  5. IPluginExecutionContext in XML format

Answer(s): B

Explanation:

The body will contain string that represents the JSON value of an instance of the RemoteExecutionContext class.

As part of the month-end financial closing process, a company uses a batch job to copy all orders into a staging database.
The staging database is used to calculate any outstanding amounts owed by clients, and must process all historical data.
You need to ensure that only the data affected during the month is included in the integration process.

What are two possible ways to achieve this goal? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

  1. Use change tracking on the orders and run the integration to retrieve new orders and the orders that have the total amount changed in the last month.
  2. Create a system view with the orders that have the Modified On field in the last month and run the integration on this subset.
  3. Use change tracking on the order lines and run the integration every week and retrieve only the order lines that have been created or deleted in the last month.
  4. Create a system view with the order lines that have the Modified On field in the last month and run the integration on this subset.

Answer(s): A,D



You are creating a Power Automate flow.
You create an Azure Service Bus listener app that receives requests from a third-party application.
When the flow calls the message queue, it must delete the message as soon as it is read.
You need to ensure that the queue is cleared properly.
Which method or class should you use?

  1. ReceiveMode
  2. BrokeredMessage
  3. EventHubReceiver
  4. EventHubSender

Answer(s): A

Explanation:

ReceiveMode enumerates the values for the receive mode. The default is PeekLock.
Fields:
PeekLock: Specifies the PeekLock receive mode. This is the default value for ReceiveMode.
ReceiveAndDelete: Specifies the ReceiveAndDelete receive mode.

Note: You can specify two different modes in which Service Bus receives messages.
-Receive and delete. In this mode, when Service Bus receives the request from the consumer, it marks the message as being consumed and returns it to the consumer application.
-Peek lock.
