Free Microsoft MB-820 Exam Actual Questions

Note: Premium Questions for MB-820 were last updated On Mar. 12, 2026 (see below)

Question #1

A company has extended Business Central.

You plan to submit the extension to AppSource.

You need to ensure that an application meets the technical requirements before submitting it for validation.

Which three actions should you perform? Each correct answer presents a complete solution.

NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution
Correct Answer: B, C, E

B. Include extension translation files with the submission.

AppSource submissions require that the extension be localized to different languages, and including translation files is part of the requirement.

C. Ensure the app file is digitally signed.

Digitally signing the app file is a security requirement for AppSource submissions to ensure the integrity and authenticity of the app.

E. Use data classification on all tables and extension fields.

Microsoft requires that all data, especially personal data, be classified using the data classification feature to comply with GDPR and other data privacy regulations.


Question #2

A company plans to set up a local Business Central Development Docker container. The environment will be used for testing new project ideas.

You need to ensure that the most recent Business Central artifact URL has been selected. Which command should you use?

Reveal Solution Hide Solution
Correct Answer: A

To ensure the most recent Business Central artifact URL is selected for setting up a local Business Central Development Docker container, the command to use is Get-BcArtifactUrl -type sandbox -select Current (A). This PowerShell command retrieves the URL for the latest available Business Central artifact for a sandbox environment, ensuring that the Docker container is set up with the most up-to-date version for testing new project ideas. The -select Current parameter is crucial as it specifies that the current, or latest, version of the artifact is to be retrieved, as opposed to selecting a version based on other criteria such as Closest, NextMinor, or NextMajor.


Question #3

You ate creating a test codeumt for a company that uses Business Central. The company requites the following list of choices while posting a sales order:

* Ship

* Invoice

* Ship & Invoice

You must create a test codeunit that automatically selects one of these options. You need to create the test codeunit Which handler should you use?

Reveal Solution Hide Solution
Correct Answer: D

StrMenuHandler is used to simulate the selection of an option from a string-based menu, such as the 'Ship,' 'Invoice,' or 'Ship & Invoice' options when posting a sales order. This handler allows you to programmatically select an option during automated testing.

Other handlers, such as SessionSettingsHandler or SendNotificationHandler, do not simulate the selection of menu choices, which is specifically required in this scenario.

For more details on StrMenuHandler and how it simulates user interaction with menu choices, refer to the Test Handlers in Business Central.


Question #4

You need to define the tables used for the non-conformity entity.

What should you use?

Reveal Solution Hide Solution
Correct Answer: B

Table Structure in Business Central: When creating entities such as 'non-conformity' entities in Business Central, you use document tables to represent entities that have a header and line structure. In this case, the non-conformity entity has:

A header with common information (Non-conformity Number, Date, Vendor No., etc.).

One or more lines representing the detailed information for each non-conforming item.

Document Table Usage:

Document Table: A document table is the correct table type for scenarios where you have a header (with general information like vendor details) and lines (with detailed, item-specific information).

Document tables are typically used for entities such as Sales Orders, Purchase Orders, or any other transactional data where you have both header and line information.

Supplemental Table (Option C):

Supplemental tables are usually used to add supplementary information to existing data in Business Central. In this case, we need to store detailed line information, which is a core part of the entity rather than supplementary data, so a supplemental table would not be appropriate here.

Document History Table (Option A):

Document history tables are used to track changes and historical data for entities but are not suitable for the main introduction of the entity and its lines. This option is also not appropriate.

Reference Documentation:

Introduction to Business Central Tables

Document Tables in Business Central


Question #5

A company plans to optimize its permission sets.

The company has the following permission sets:

You need to provide the following implementation for a third permission set:

* Create a new Permission Set C that is a composite of Permission Set A and Permission Set B.

* Assign Permission Set C to a user.

You need to ensure that the user has only read access to the Job table.

Solution: Set the IncludedPermissionSets property to Permission Set B and the ExcludedPermissionSets property to Permission Set A.

Does the solution meet the goal?

Correct Answer: B
