NEW QUESTION # 12
A company plans to integrate tests with its build pipelines.
The company has two Docket sandbox environments: SandboxA and SandboxB.
You observe the following:
* SandboxA is configured without the Test Toolkit installed.
* SandboxB must be configured from scratch. The Test Toolkit must be installed in SandboxB during configuration.
You need to configure the sandbox environments.
How should you complete the cmdlets? To answer, select the appropriate options in the answer area.
Answer:
Explanation:
Explanation:
Based on the PowerShell script snippet you've provided and the scenario described, you need to configure Docker sandbox environments for a company with specific requirements for Test Toolkit installations.
For SandboxA, since it is configured without the Test Toolkit installed, you would typically use the PowerShell cmdlet Install-TestToolkitToBcContainer to install the Test Toolkit into the Business Central Docker container.
For SandboxB, which must be configured from scratch with the Test Toolkit installed during configuration, you would include the Test Toolkit as part of the New-BcContainer script block that creates the container.
The relevant cmdlets and parameters for SandboxB would include:
* -includeTestToolkit: This parameter ensures that the Test Toolkit is included during the creation of the new container.
Given the limited context from the image, here's how you should complete the cmdlets for SandboxB:
* Add -includeTestToolkit in the New-BcContainer script to ensure the Test Toolkit is installed when creating SandboxB.
* Since you are setting up SandboxB from scratch, you don't need to run Install- TestToolkitToBcContainer separately as the toolkit will be included at the time of container creation with the -includeTestToolkit parameter.
For the New-BcContainer cmdlet, you would fill in the placeholders with the appropriate values for artifactUrl, imageName, and licenseFile if they are required for your specific setup.

NEW QUESTION # 19
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
Answer: A
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.
NEW QUESTION # 20
You create a table with fields.
You observe errors in the code
You need to resolve the errors.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
* In line 12, declare "Job Task" as a variable. = NO
* Add the property FieldClass = FlowField; for field 3. = YES
* Add the property FieldClass = FlowFilter; for field 3. = NO
* In line 23, assign the "User Setup" table to a field. = YES
For "In line 12, declare 'Job Task' as a variable": In the AL code provided, the "Job Task" appears to be part of a CalcFormula of a FlowField, which means it references a table and not a variable. The "Job Task" does not need to be declared as a variable because it is used to reference a table in a CalcFormula expression.
For "Add the property FieldClass = FlowField; for field 3": The line of code CalcFormula = sum("Job Task
"."Recognized Sales Amount" where("Job No." = field("No."))); indicates that this field is calculated from other table data, which is the definition of a FlowField. Therefore, adding the property FieldClass = FlowField; is necessary for the field to function correctly.
For "Add the property FieldClass = FlowFilter; for field 3": FlowFilters are used to filter data based on the value in a flow field. Since field 3 is using a CalcFormula to sum values, it is a FlowField and not a FlowFilter. Therefore, this statement is not correct.
For "In line 23, assign the 'User Setup' table to a field": The line TableRelation = "User Setup"; suggests that the "Project Manager" field has a relation to the "User Setup" table, which is a method of assigning a table to a field to ensure that the values in "Project Manager" correspond to values in the "User Setup" table.
Hence, this statement is true.
NEW QUESTION # 21
You need to define the data types for the fields of the N on-conformity table.
Which two data types should you use? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A. Code for the Non-Conformity Number field
- B. Date Time for the Non-Conformity Date field
- C. Char for the Non-Conformity Number field
- D. Integer for the N on-conformity Number field
- E. Date for the Non-Conformity Date field
Answer: A,C
Explanation:
In Business Central, fields in tables are assigned specific data types that determine the kind of data they can store. For the Non-conformity table mentioned in the case study, the following data types should be used:
* Date for the Non-Conformity Date field: This is because the Non-conformity Date field is required to store only the date when the non-conformity was recorded. The Date data type is appropriate for storing dates without times.
* Code for the Non-Conformity Number field: The Non-conformity Number field is described to use alphanumeric values with a format that includes "NC" and the year, like "NC24-001". In Business Central, the Code data type is used for fields that store alphanumeric keys. It is a text field with a limited length, which makes it suitable for number series that contain letters and numbers.
Other options are not suitable:
* A. Integer for the Non-conformity Number field: This would not be appropriate because the Non- conformity Number includes alphanumeric characters and not just integers.
* B. DateTime for the Non-Conformity Date field: This is not correct because there is no requirement to store the time alongside the date.
* C. Char for the Non-Conformity Number field: Char data type is not typically used in Business Central for number series or identifiers. The Code data type is preferred for this purpose.
NEW QUESTION # 22
You need to determine If you have unwanted incoming web service calls in your tenant during the last seven days.
Which two KQL queries should you use? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
- A.
- B.
- C.
- D.
- E.
Answer: B,C
Explanation:
The task is to identify unwanted incoming web service calls during the last seven days. To do this, we need to look at KQL (Kusto Query Language) queries that would filter out web service calls based on the timestamp (to ensure the calls are within the last seven days) and by certain characteristics that would indicate they are unwanted, such as the wrong type of protocol (SOAP in this case, as Contoso Ltd. plans to dismiss using it).
Looking at the options:
* Option A: This query selects all traces where the timestamp is within the last 7 days and where the custom dimension has a value of 'RT0008', and where the category is either 'ODataV4', 'ODataV3', or
'Api'. This query would show all API calls except SOAP, so it does not directly answer the question about unwanted calls.
* Option B: This query filters for traces with a timestamp within the last 7 days, where 'RT0008' is present, and specifically looks for the category 'SOAP'. This query is correct because it directly targets SOAP calls, which are the unwanted calls according to Contoso Ltd.'s plans.
* Option C: Similar to option B, this query filters for traces within the last 7 days and looks for 'RT0008' but uses the equality operator for the category 'SOAP'. This would also correctly return the unwanted SOAP calls.
* Option D: This query also filters for traces within the last 7 days, but it excludes the 'ODataV4' category, which doesn't necessarily target the unwanted SOAP calls.
* Option E: This query selects traces where the timestamp is within the last 7 days and the custom dimension has 'RT0008'. However, it filters out categories 'ODataV4' and 'Api', which does not directly help in identifying the unwanted SOAP calls.
Therefore, the queries that should be used to determine if there are unwanted incoming web service calls (SOAP calls) in the tenant during the last seven days are Options B and C. These queries are specific to identifying SOAP protocol usage, which is what Contoso Ltd. considers unwanted.
NEW QUESTION # 23

3 - Select the Application Insights instance, select Logs and then inspect the Traces table.
NEW QUESTION # 25
A company uses Business Central.
The company plans to use a translation file in an extension. The extension has a caption that should not be translated.
You need to prevent the caption from being translated.
What should you do?
- A. Use the CaptionML property and copy the same caption for each language used.
- B. Delete the Caption property.
- C. Add the Locked = true parameter to the Caption.
- D. Set the GenerateLockedTranslations feature in the appjson file.
- E. Copy the same caption for each language in the translation file.
Answer: C
Explanation:
To prevent a caption from being translated in an extension for Microsoft Dynamics 365 Business Central, you should add the Locked = true parameter to the Caption (C). This parameter explicitly marks the caption as locked for translation, ensuring that it remains unchanged across different language versions of the extension.
This approach is useful for specific terms, brand names, or other elements within the application that should remain consistent regardless of the user's language settings. Unlike the other options, which involve manual manipulation of the translation file or properties, setting Locked = true directly in the AL code provides a clear, maintainable, and error-proof method to exclude specific captions from the translation process.
