46. Frage
You need to write the code to call the subcontractor's REST API.
How should you complete the code segment? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Antwort:
Begründung:
Explanation:
To correctly write the code to call the subcontractor's REST API, you would need to set the Authorization header with the base64 encoded username and password for basic authentication. The code segment indicates the use of the Base64Convert codeunit to convert the username and password to base64 format, which is then prefixed with "Basic " to form the proper Authorization header value.
The correct method to add the Authorization header to the RequestHeaders would be:
RequestHeaders.Add('Authorization', 'Basic ' + Base64Convert.ToBase64(Username + ':' + Password)); And the correct method to set the httpContent with the body of the request would be:
httpContent.WriteFrom(Body);
These are the necessary steps to form a well-structured HTTP request for basic authentication and to include the body of the request in the API call.
47. Frage
A company is deploying Business Central on-premises.
The company plans to use a single-tenant deployment architecture.
You need to describe how the data is stored and how the Business Central Server is configured.
In which two ways should you describe the single-tenant architecture? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
Antwort: A,D
Begründung:
Single tenant provides each customer with a distinct software instance running on infrastructure that is not shared with other users. Multi-tenant uses a shared infrastructure to provide access to the SaaS solution to multiple customers.
In a single-tenant deployment architecture, the application data and business (tenant) data are stored in the same database. That is, there's only one database. If you want to set up single- tenant deployment, you only have to create an application database.

48. Frage
You are developing an app that will be published to Microsoft AppSource.
The app requires code analyzers to enforce some rules. You plan to add the analyzers to the settings.json file.
You need to activate the analyzers for the project.
Which three code analyzers should you activate to develop the app for AppSource? Each correct answer presents part of the solution NOTE: Each correct selection is worth one point.
Antwort: A,B,E
Begründung:
When developing an app for Microsoft AppSource, it is crucial to adhere to specific guidelines and standards to ensure compatibility and compliance. The three code analyzers you should activate are:
CodeCop (A): This is the default analyzer for AL language extensions. It enforces the AL Coding Guidelines, ensuring that the code follows best practices for readability, maintainability, and performance. It checks for a wide range of issues, from syntax errors to best practice violations, making it essential for any AL development.
PerTenantExtensionCop (D): This analyzer is specifically designed for extensions that are intended to be installed for individual tenants. It includes rules that ensure the extension does not interfere with the per-tenant customizations and adheres to the guidelines for extensions that can be safely installed and uninstalled without affecting the underlying application.
AppSourceCop (E): This analyzer is tailored for extensions that are intended for publication on Microsoft AppSource. It enforces additional rules that are specific to AppSource submissions, such as checking for the use of reserved object ranges and ensuring that all prerequisite dependencies are correctly declared. This is crucial for ensuring that your app meets all the requirements for listing on AppSource.
By activating these three analyzers, developers can ensure their app adheres to the standards required for AppSource, as well as maintain high code quality and compatibility with Business Central.

Hotspot Question
A company plans to import and export data with Business Central.
You must configure an XMLport that provides the following implementation:
- Specifies import 01 export on the Request page at run time
- Formats the data in a non-fixed length CSV format
You need to create the XMLport.
How should you complete the code segment? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Antwort:
Begründung:
Explanation:
Box 1: Both
You are configuring an XMLport for Business Central with the following requirements:
Specifies import or export on the Request page at runtime.
Formats the data in a non-fixed length CSV format.
XMLport Configuration:
Specifies import or export on the Request page at runtime.
The Direction property must be set to Both.
This allows the XMLport to both import and export data depending on user selection during runtime.
Box 2: Format= VariableText
Formats the data in a non-fixed length CSV format.
The Format property must be set to VariableText.
VariableText is used for delimited text formats like CSV, which do not have a fixed length for fields.
50. Frage
A company is examining Connect apps and Add-on apps for use with Business Central.
You need to describe the development language requirements for Connect apps and Add-on apps.
How should you describe the app language requirements? To answer, move the appropriate app types to the correct descriptions. You may use each app type once, more than once, or not at all. You may need to move the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Antwort:
Begründung:
Explanation:
* Developed by using any coding language: Connect app
* Developed by using AL language in Visual Studio Code: Add-on app
In Microsoft Dynamics 365 Business Central, there are distinct types of applications that can be developed:
Connect apps and Add-on apps. Each has its own development language requirements:
* Connect apps:
* Connect apps are designed to connect Business Central with external services or applications.
They are often developed using a variety of programming languages, not limited to the AL language, and can be hosted outside of the Business Central environment. Therefore, when a description states that the app is developed using any coding language, it generally refers to a Connect app. This type of app integrates with Business Central through APIs and web services.
* Add-on apps:
* Add-on apps are built to extend the functionality of Business Central within the application itself.
These are developed using the AL language, which is the programming language for Business Central, and they are created and managed within the Visual Studio Code environment with the AL Language extension. An Add-on app is typically a Business Central extension that is directly installed into the Business Central environment.
The language and environment used for developing these apps are key differentiators between Connect apps and Add-on apps.
