Question # 1
You need to determine why the debugger does not start correctly.
What is the cause of the problem? | A. The "userld" parameter must have the GUID of the user specified, not the username. | B. The "breakOnNext" parameter is not set to -WebServiceClient". | C. The "userld" parameter is specified, and the next user session that is specified in the 'breakOnNext" parameter is snapshot debugged. | D. The "executionContext* parameter is not set to "Debug". |
A. The "userld" parameter must have the GUID of the user specified, not the username.
Explanation:
In Microsoft Dynamics 365 Business Central, when configuring snapshot debugging, it is crucial that the parameters in the configuration file are correctly set. From the options provided, the issue with the debugger not starting correctly is most likely due to an incorrect "userId" parameter.
Option A is the cause of the problem. The "userId" parameter must be the GUID of the user, not the username. The snapshot debugger needs the exact GUID to attach to the right session for debugging.
Option B is incorrect because "breakOnNext" set to "WebClient" is a valid setting. This tells the debugger to break on the next client action in the web client, which is a typical scenario.
Option C is not the cause of the problem. The "userId" parameter is meant to specify which user session to debug, and this works in conjunction with the "breakOnNext" parameter.
Option D is incorrect as the "executionContext" parameter does not need to be set to "Debug" for snapshot debugging to work. "DebugAndProfile" is a valid value for the "executionContext" parameter, as it allows for debugging and collecting performance information.
Therefore, the reason why the debugger does not start correctly is due to Option A: The "userId" parameter must have the GUID of the user specified, not the username.
Question # 2
You plan to write unit test functions to test newly developed functionality in an app.
You must create a test codeunit to write the functions.
You need to select the property to use for the test codeunit.
Which property should you use to ensure that the requirements are fulfilled? | A. SubType | B. Access | C. Description |
A. SubType
Explanation:
When creating a test codeunit in Microsoft Dynamics 365 Business Central to write unit test functions, the SubType property (A) of the codeunit should be set to Test. This property is crucial for defining the codeunit's purpose and behavior within the application. By setting the SubType property to Test, you are indicating that the codeunit contains test functions intended to validate the functionality of other parts of the application, such as customizations or new developments. This distinction ensures that the testing framework within Business Central recognizes the codeunit as a container for test functions, allowing it to execute these functions in a testing context, which can include setting up test data, running the tests, and cleaning up after the tests have completed.
Question # 3
You need to improve performance when ticketAPI is used to analyze the POS data. What should you do? | A. Set the ODataReadonlyGetEnabled parameter to True in the Business Central admin center. | B. Set the AceesByPermission property to Read on the ticketAPI API page. | C. Enable read scale-out on the Business Central database. | D. Set the DataAccesslntent property to Readonly on the ticketAPI API page. |
C. Enable read scale-out on the Business Central database.
Explanation:
Read Scale-Out:
Read scale-out is a feature in Business Central that allows you to improve performance by distributing read-only queries (such as the ones from the ticketAPI) across multiple read replicas in the cloud database. This reduces the load on the primary database and helps improve the response time for read-intensive operations, like analyzing POS data through the ticketAPI.
Data Access Intent - ReadOnly:
When enabling read scale-out, you can configure the DataAccessIntent property of APIs to be ReadOnly. This directs the system to use read replicas to handle read-only queries, which enhances performance by offloading such queries from the primary database.
Why Not Other Options?
Option A (ODataReadonlyGetEnabled): This parameter is unrelated to read scale-out and primarily affects OData services behavior, not API performance tuning.
Option B (AccessByPermission): Setting the permission to Read does not directly affect the performance. It only controls access based on user permissions.
Option D (DataAccessIntent ReadOnly): While setting this property to ReadOnly helps in read-only operations, enabling read scale-out (option C) ensures the underlying infrastructure is optimized to handle such read operations, which is the fundamental action required.

Question # 4
You are cleaning up sandbox environments for a company.
The company requires data to be cleared from the environments each time an extension is published.
You need to configure the launch.json file.
Which schemaUpdateMode property should you set? | A. ForceUpgrade | B. ForceSync | C. Synchronize | D. Recreate |
D. Recreate
Explanation:
In the context of cleaning up sandbox environments for a company where data needs to be cleared each time an extension is published, the schemaUpdateMode property in the launch.json file should be set to Recreate (D). Setting this property to Recreate ensures that every time the extension is published, the existing tables and data are dropped, and then the tables are recreated based on the current extension's schema. This mode is particularly useful in development and testing environments where you need a clean slate for testing each version of the extension without the remnants of previous data affecting the outcomes. It's important to use this setting cautiously, as it results in the loss of all existing data in the tables defined by the extension, which is suitable for a sandbox environment but not for production environments.
Question # 5
You are exporting data from Business Central.
You must export the data in a non-fixed length and width in CSV format.
You need to generate an XMLport to export the data in the required format
Which Format property value should you use? | A. XML | B. VariableText | C. FixedText |
B. VariableText
Explanation:
When exporting data from Business Central and the requirement is for the data to be in a non-fixed length and width CSV format, the Format property of the XMLport should be set to VariableText (B). The VariableText format is designed for handling data exports where the fields are separated by a delimiter, such as a comma or tab, which is typical of CSV (Comma-Separated Values) files. This format allows for the flexibility needed when dealing with varying field lengths, as it does not enforce a fixed width for each field, making it ideal for CSV data exports. Setting the Format property to FixedText (C) would enforce a fixed width for each field, which is not suitable for CSV files, while the XML format (A) is used for exporting data in an XML structure, which is different from the CSV format requirements.
Question # 6
You are creating an entitlement object in Business Central to enable transactability for AppSource apps.
You must map the entitlement object to a plan in Partner Center.
You need to select the value of the Type property to use in the entitlement object.
Which value should you use? | A. PerUserServicePlan | B. Implicit | C. Unlicensed | D. Role |
A. PerUserServicePlan
Explanation:
In Business Central, when creating an entitlement object to enable transactability for AppSource apps and mapping it to a plan in Partner Center, the Type property of the entitlement object should be set to PerUserServicePlan (A). The PerUserServicePlan type is used to define an entitlement that is based on a service plan, which is typically how transactability features are managed for apps distributed through AppSource. This type of entitlement allows for the mapping of specific features or capabilities of the app to a service plan in Partner Center, enabling granular control over what users are entitled to use based on their subscription. The other values, such as Implicit (B), Unlicensed (C), and Role (D), are used in different contexts and do not apply to the scenario of mapping an entitlement object to a plan for AppSource apps.
Question # 7
A company has a test application.
A user observes the following error messages when running the test:
• "Unhandled Ul: Message'
• "Unhandled Ul: Confirm"
You need to resolve the errors. Which action should you take?
| A. Create a separate test runner codeunit that has Message Handler and Confirm Handler methods. | B. Create the Message Handler and Confirm Handler methods in the test runner codeunit. | C. Create a separate test codeunit that has Message Handler and Confirm Handler methods. | D. Create the Message Handler and Confirm Handler methods in the test codeunit. |
B. Create the Message Handler and Confirm Handler methods in the test runner codeunit.
Explanation:
A user observes error messages such as:
"Unhandled UI: Message"
"Unhandled UI: Confirm"
These messages indicate that the test code is not handling system prompts like Message and Confirm dialogs, which can appear during test execution.
Options Explanation:
Message Handler and Confirm Handler methods are used to intercept and handle these UI prompts during automated testing.
These methods should be added to the test runner codeunit, which is responsible for running the tests and handling these system-level interactions.
