Sample Practice Questions (MB-820: Microsoft Dynamics 365 Business Central Developer)

Try these sample questions before moving to the full interactive quiz below. Each question includes the correct answer and explanation to help you understand the concepts tested in a MB-820: Microsoft Dynamics 365 Business Central Developer exam.

1 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 Integer for the N on-conformity Number field
B Date Time for the Non-Conformity Date field
C Char for the Non-Conformity Number field
D Date for the Non-Conformity Date field
E Code for the Non-Conformity Number field
Answer: D, E
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.

2 You need to access the RoomsAPI API from the canvas app. What should you do?

A Use the default API configuration in Business Central
B Enable the APIs for the Business Central online environment.
C Open the Web Services page and publish the RoomsAPI page as a web service.
D Include in the extension a codeunit of type Install that publishes RoomsAPI.
Answer: D
API Publishing for Extensions: In Business Central, when creating custom APIs like RoomsAPI, it is important to ensure that they are automatically published during the installation or upgrade of the extension. To achieve this, you can include a codeunit of type Install in the extension that explicitly publishes the custom API (RoomsAPI) as a web service. This ensures that it is available for use immediately after the extension is deployed without requiring manual intervention. Codeunit Type: A codeunit of type Install runs when the extension is installed or upgraded. This type of codeunit can be used to perform setup tasks such as publishing web services or APIs like RoomsAPI. Why Not Other Options? Option A (default API configuration): This would not automatically publish the RoomsAPI. Default APIs do not cover custom APIs. Option B (enable APIs for the environment): Enabling APIs in Business Central allows the standard APIs to be used, but custom APIs still need to be manually published. Option C (publish via Web Services page): This would work but requires manual intervention to publish RoomsAPI, which does not fulfill the requirement of automatic publishing during installation.

Main exam topic areas

The MB-820 certification covers six official skill areas.

  • Describe Business Central, 10 to 15 percent. It covers architecture, apps, update lifecycle, and the difference between online and on-premises features.
  • Install, develop, and deploy for Business Central, 10 to 15 percent. It covers the development environment, configuration files, debugging, deployment, and multilanguage setup.
  • Develop by using AL objects, 35 to 40 percent. It covers tables, pages, reports, XMLports, codeunits, permissions, queries, and extensions.
  • Develop by using AL, 15 to 20 percent. It covers UI work, standards, custom code, variables, errors, and access control.
  • Work with development tools, 10 to 15 percent. It covers testing, the test toolkit, and telemetry.
  • Integrate Business Central with other applications, 10 to 15 percent. It covers REST, JSON, APIs, OData actions, and read scale-out.

Those are the areas to study if you want a focused review of the current exam shape.

How to register for the exam

If you are using Microsoft MB-820 Dumps as a study aid, keep the live booking rules separate from the practice material. The MB-820 certification is not tied to a class list, so you book an open appointment instead of waiting for a limited vacancy. You can usually book up to 90 days ahead, so the exam runs when you reserve a slot.

The exam scheduling page explains the booking flow, and it sends you to the provider site where you pick the date, delivery mode, and payment step.

For a study path before you book, the practice home page , the exam category page , and the timed quiz simulator give you a simple starting set. The price depends on the country or region where the test is proctored, and there is no fixed class date because you choose from the calendar when a seat is open.

Where you can take the exam

When you move from Microsoft MB-820 Dumps study notes to the live test, you can choose either an online proctored appointment or a test center visit for the MB-820 certification. In the United States, the scheduler shows which delivery mode is open for your date, so the best choice depends on the slot you pick and the setup you prefer. If you choose online, run the system precheck before exam day so the computer is ready.

Exam format, timing, and scoring

For Microsoft MB-820 Dumps study, keep in mind that the live exam is proctored and may include interactive items. The MB-820 certification uses a scaled score, and the published passing score is 700 or higher.

Microsoft MB-820 Dumps should help you map the topic mix, but it cannot replace the live scoring rules. Plan for 100 minutes of test time and about 120 minutes of seat time, because the full session includes the setup and review steps.

You only need to pass MB-820 once for this path, and the question count can change from one sitting to another.

Who this exam fits best

If you build or support Business Central solutions, Microsoft MB-820 Dumps can help you see where your applied knowledge is thin. Microsoft MB-820 Dumps also make more sense for people who already work with AL, extensions, or deployment, because the exam expects hands-on understanding.

The exam guidance does not list a degree requirement, but it does expect applied knowledge of Business Central, the AL language, the development environment, and related tools. If you already work with ALM, source control, and continuous delivery, the material will feel more practical.

Developers, support engineers, solution architects, and business analysts often fit the content best.

How hard the exam feels

Microsoft MB-820 Dumps can make the outline look simple, but the real exam still asks you to connect many moving parts. There is no published pass rate to use as a shortcut, so the better way to judge difficulty is to compare the exam with your own daily work.

It feels easier when you already build extensions and debug issues in Business Central, but it gets harder if you only read theory and do not practice in the tool.

Professional value after you pass

Microsoft MB-820 Dumps review can help you organize the work you already do into clear study notes. Later, Microsoft MB-820 Dumps can also help you speak about Business Central with more control in meetings, interviews, and project talks.

That matters because the exam covers the same kinds of tasks you meet in real jobs, such as extensions, troubleshooting, testing, telemetry, and integration.

A practical plan to prepare

A focused plan built around the study guide, hands-on labs, and Microsoft MB-820 Dumps review can keep your study time tight. The MB-820 certification becomes easier to read when you pair that review with the Certification-Exam Simulator and Mobile App, because short repeats help memory stick.

Before your final pass, read the study guide page and compare it with the PDF study guide and the timed quiz simulator . The quiz flow works like a timed mock exam, and the question bank lets you go back through the same ideas without rushing.

If you have time, use the quiz simulator and the mobile app in short blocks, then do one longer run to see how your timing holds up.

Practice with Certification-Exam quiz features

After you understand the official exam structure, you can strengthen your prep with Certification-Exam practice quizzes that simulate real test conditions. If you want a fast run, the timed quiz simulator keeps the same browser flow, so you can focus on timing and recall.

The total number of available practice questions is 117. Each complete practice session uses a time limit of 120 minutes. The average success or completion trend is 70 percent. The scoring system works like this: 1 point for a correct answer, 0 points for an incorrect answer, and 0 points for an unanswered question.
