Free MB-820: Microsoft Dynamics 365 Business Central Developer (beta) Exam Questions and Answers

Correct answer: D, E

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.

Correct answer: A

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.

Correct answer: Yes; Yes; Yes

Correct answer: C

Explanation

The ToolTip property supplies the descriptive help text shown for a field when a user hovers over it, which is the typical way to provide explanatory values for fields like Description and Comments.

Correct answer: A, B

Explanation

In a single-tenant on-premises deployment each customer has a dedicated Business Central Server instance, and the application objects and the business data are stored together in one database.

Correct answer: E

Explanation

• Permission sets control access to objects (such as pages, tables, reports) in Business Central. By creating a new permission set that specifically excludes the critical table (or page) and assigning this permission set to the users in Department A, you can prevent them from accessing the page. • Option A (creating a different role center page) is incorrect because role centers control the user interface, but do not directly restrict access to specific pages or tables. • Option B and Option C (extending the base application permission set) are not the best options because extending permission sets typically involves adding permissions, not removing access. The question requires restricting access to a critical page, so simply including or excluding permission sets won't solve the issue at the table or page level. • Option D (creating an entitlement object) is not relevant here, as entitlements are used in more complex licensing scenarios or environments. Summary: Creating a permission set object that specifically excludes access to the critical table or page and assigning it to the users will solve the problem effectively.

Correct answer: C

Explanation

SharedLayout = false specifies that the view has its own custom layout instead of sharing the page layout. The Customer table exposes the local-currency balance as the "Balance (LCY)" field, so the filter is where("Balance (LCY)" = filter(> 500)).

Correct answer: E

Explanation

XMLport OverviewIn Microsoft Dynamics 365 Business Central, XMLports are used for importing and exporting data in XML, CSV, or other text formats. By default, XMLports are designed to work with XML data, but they can also handle delimited text formats like CSV (Comma-Separated Values). Requirement ClarificationThe requirement is to change the export format from XML to CSV. CSV is a text-based format, not an XML format. To accommodate this, you need to change how the XMLport handles data during export. Properties of XMLport • The Format property in XMLports controls whether the output format is XML or a text-based format such as CSV. • The VariableText option of the Format property specifies that the data should be exported in a variable text format, like CSV. • The XMLports default to an XML format, but by setting the Format property to VariableText, you can change the export to CSV format or another text-delimited format. of Correct Answer (E)To switch from XML to CSV export: • You need to change the Format property of the XMLport to VariableText. • The VariableText option allows for the export of data in a non-XML format, which is precisely what CSV represents (a comma-delimited text file). Why Other Options Are Incorrect • Option A (Change the Direction property to Both):The Direction property controls whether the XMLport is used for Import, Export, or Both (import and export), but it does not affect the file format (XML vs. CSV). Hence, this is irrelevant to the file format change. • Option B (Change the FormatEvaluate property to Legacy):The FormatEvaluate property is not related to changing the export format. It deals with the evaluation of the data format during the processing but doesn't change the format type (XML or CSV). • Option C (Change the XmlVeisionNo property to 1.1):The XmlVersionNo property defines the XML version used for the export (such as 1.0 or 1.1). This only applies to XML exports and does not change the format to CSV. • Option D (Fill the FileName property with Items.csv):While this option would specify the name of the file being exported (i.e., "Items.csv"), it doesn't control the format of the export itself. The actual format change is controlled by the Format property. Developer Reference from Microsoft DocumentationAccording to the official Microsoft documentation for XMLports in Business Central, the Format property is critical for determining how data is structured for export. To change the file format from XML to CSV, developers need to set the Format property to VariableText. This allows for export in a text-delimited format, which is ideal for CSV. • XMLport Properties - Format Property • How to: Export Data in Text Format Using XMLports

Correct answer: B

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.

Correct answer: C
