• Question 231:

  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?

  A. ReceiveMode

  B. BrokeredMessage

  C. EventHubReceiver

  D. EventHubSender

  Correct Answer: A

  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.

• Question 233:

  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.

  A. 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.

  B. Create a system view with the orders that have the Modified On field in the last month and run the integration on this subset.

  C. 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.

  C: The change tracking feature in Microsoft Dataverse provides a way to keep the data synchronized in an efficient manner by detecting what data has changed since the data was initially extracted or last synchronized. Deletions and creations are tracked.

  D: On modified Order Lines, not on Modified Orders.

• Question 235:

  You deploy a Power Platform plug-in to a production environment. The plug-in code contains detailed tracing information. You are a member of the Environment Maker security role for the environment.

  Users report unexpected results when they interact with confidential data by using the plug- in. You confirm that the plug-in works without errors in a development environment.

  You need to investigate the root cause of the plug-in errors.

  What should you do?

  A. Send a PUT request to enable plug-in tracing for the production environment.

  B. Send a GET request to retrieve the plugintracelogs records.

  C. Install Plug-in profiler in the production environment by using the Plug-in Registration tool.

  D. Reproduce and capture the errors, then debug from Visual Studio.

  Correct Answer: C

  Plug-in profiler is a solution that you can install on your environment that enables you to capture the execution context of a plug-in and then use that data to re-play the event within Visual Studio while debugging.

  There are two tools available from which to run the Plug-in Profiler:

  the Plug-in Registration Tool and Power Platform Tools for Visual Studio.
