A company plans to deploy Business Central.
The company has the following deployment requirements:
• Use the company hardware architecture to run the deployment.
• Use sandbox environments to develop extensions.
• Allow tenants to connect to Shopify with the standard connector.
• Use Microsoft Power Automate to create a workflow that calls a business event.
You need to identify the deployment type for each requirement.
Which deployment types should you use? To answer, move the appropriate deployment types to the correct requirements. You may use each deployment type once, more than once, or not at all.
정답:
Explanation:
Use the company hardware architecture to run the deployment: On-premises
Use sandbox environments to develop extensions: Online
Allow tenants to connect to Shopify with the standard connector: Online
Use Microsoft Power Automate to create a workflow that calls a business event: Online
When deploying Microsoft Dynamics 365 Business Central, there are two main deployment types to
consider: On-premises and Online.
On-premises Deployment:
The requirement to use the company's hardware architecture implies a need for an on-premises
deployment. This is because on-premises deployment allows for the application to be installed and
run directly from the company's in-house servers and computing infrastructure, giving full control
over the environment and data.
Online Deployment:
The use of sandbox environments for developing extensions is a feature provided in the online version of Business Central. Sandbox environments are a part of the service offered in the cloud-based version, which allows developers to test and develop without affecting the live environment. Connection to Shopify with the standard connector implies an online deployment. The standard connector is typically a cloud-based service that allows Business Central to connect with other cloud platforms like Shopify, which is more seamlessly integrated with the online version.
Lastly, the use of Microsoft Power Automate to create a workflow that calls a business event suggests an online deployment. Power Automate is a cloud-based service designed to create automated workflows between applications and services - which aligns with the services provided by the online version of Business Central.
Therefore, each requirement aligns with the deployment types as indicated above.
Question No : 2
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.
정답: Explanation:
In a single-tenant deployment architecture of Business Central on-premises, the following characteristics describe how the data is stored and how the Business Central Server is configured: The application and the business data are stored in the same database (B): In a single-tenant architecture, each tenant (which typically corresponds to a single customer) has its own dedicated database. This database contains both the application objects (such as pages, reports, codeunits, etc.) and the business data (such as customer, vendor, and transaction records). This setup ensures that each tenant's data is isolated and can be managed independently.
The application and business data are stored in separate databases (D): While (B) is a characteristic of a single-tenant deployment, it's important to clarify that in some configurations, the application objects can be stored in a separate database from the business data. This approach can be used for easier maintenance and upgrades of the application code without affecting the business data. However, each tenant still has its own set of databases, maintaining the single-tenancy model. The other options provided do not accurately describe a single-tenant architecture:
Each customer has their own Business Central Server (A): This statement might be misleading. In a single-tenant deployment, while each customer has their own database, they do not necessarily have their own Business Central Server instance. Multiple databases (tenants) can be hosted on a single server instance, although they are not shared across customers.
Multiple customers share a single Business Central Server (C) and Multiple customers share multiple Business Central Server instances (E): These options describe a multi-tenant architecture rather than
a single-tenant one. In a multi-tenant setup, multiple customers (tenants) can share the same server instance and even the same application database, with data isolation ensured at the application level.
Question No : 3
You are developing an app.
You plan to publish the app to Microsoft AppSource.
You need to assign an object range for the app.
Which object range should you use?
정답: Explanation:
When developing an app for Microsoft AppSource, it is essential to use an object range that is specifically designated by Microsoft to avoid conflicts with other apps and the base application.
The correct object range to use is:
An object range within the range of 70000000 to 74999999 that is requested from Microsoft (D): This range is reserved for AppSource apps. Developers need to request this range from Microsoft to ensure that the objects used in their extension do not conflict with those used by other extensions or by the base application. Using this reserved range helps maintain the integrity and compatibility of extensions published on AppSource.
It's important to note that the other ranges mentioned (A, B, C, and E) are not suitable for apps intended for AppSource. Ranges 50000 to 59999 and 50000 to 99999 are typically reserved for per-tenant customizations or partner solutions, not for distribution on AppSource. The standard range 1 to 49999 is reserved for the base application objects, and using an object range divided by countries (C) is not a standard practice for AppSource apps.

Topic 4, Misc. Questions
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.
정답: Explanation:
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.

Topic 3, Fabrikam Inc
Company background and technical environment
Current environment
Fabrikam Inc. is a medium-sized company that plans to implement Dynamics 365 Business Central as an ERP system. The company has a development department that will help with the ERP implementation.
Most employees work remotely from different countries or regions and speak different languages.
The various locations and languages cause issues with the current on-premises software.
Planned improvements
Fabrikam Inc. plans to implement new and modern software to manage the company. The company wants to use Business Central because it is cloud-based and meets all company requirements.
The company intends to improve reporting and integration functionality by using modern tools such as Power BI and APIs. To reduce the amount of information sent by email, the company plans to expose vendor information to be consumed from external users.
Technical specifications
The development department installed Visual Studio Code to create Business Central extensions so the ERP system could be customized according to company needs. All extensions must be developed for the Business Central 2024 wave 1 online version.
The development department plans to use telemetry to control the appropriate use of each new development and works directly in licensed sandbox environments supplied by Microsoft.
The following departments at Fabrikam Inc. have multiple requirements:
• Development
• Control
• Accounting
• Quality
Development department
The development department designed an extension for the purchase department. Because the developers plan to work with telemetry for monitoring operations, they need the Application Insights information. To accomplish this, the department must add a setting in the corresponding file. The quality department does not want to receive any warning about the Application Insights setting when the extension is compiled.
Control department
The control department requires customization to Business Central by using a per-tenant extension (PTE) named Subcontract Docs. The PTE includes a table named Subcontract Documents.
The table has the following fields:
• ID: A unique identifier
• Subcontract No.: Related to the standard Vendors table
• Description: A short description of a received document
• Document: A media type that has the document
• Comments: Comments about the document
• Date: When the document was imported
• Amount: Amount related with the imported document
• Posted Indicates if the document is managed
The extension must be in English - United States (ENU) and Spanish Traditional Sort (ESP) so the application can be used in both languages. The translations must be on the table, not on the page, to avoid repeating them. The control department does not want to use translation files.
The control department manager requires a brief guide for the Description and Comments fields when employees create a new record so users know what to include in the fields. The guide must disappear as soon as users add a value in the fields.
The Subcontract Documents table must be displayed on a new page named Subcontract Document List through an action from the standard Vendor page.
The Amount field, included in the Subcontract Document List, must be formatted in bold format when the record is posted (field Posted = true).
The control department also requires a report to display a list of subcontract documents named Subcontract Documents Excel List.
The report must meet the following requirements:
• Downloads a file only in Microsoft Excel.
• Includes a predefined format with two worksheets; one with the posted subcontract documents and another with the unposted subcontract documents.
Accounting department
The accounting department plans to use Power Bl to analyze information generated by the control department. The accounting department plans to expose an API named API Customer Lines. To improve the performance, the API must use read-only information and work with a Query object to summarize the data.
The accounting department must expose data such as the following.
The qty column must be the sum of the Outstanding quantity field of Sales Order Lines. It must be in descending order by quantity.
The department also exposes a page named Fabrikam Vendor API that includes vendor information from the Vendor table, such as number and name. The API must use the replica database to improve performance.
Because Fabrikam Inc. is based in multiple countries and regions, the company periodically must send accounting movements between two dates to the local tax offices named Fabrikam Accounting. The format for this file must be an XML file generated by an XMLport object. For security reasons, it is not possible to receive data from this XMLport.
The department has a version 1.0.0.1 installed for an extension named Quality Control. The department develops a new version 1.0.0.2 and uses a codeunit with the subtype Upgrade to update it. The department requires the values for AppVersion and DataVeision on the tnaaer OnUoaradePerCompany after using NavAocGetCurrentModulelnformation.
The generated XML file must have a schema like this:
Quality department
The quality department requires that every new app or extension is designed to meet standard company guidelines. The quality department plans to follow the standard Business Central data model. The quality development must be able to use triggers correctly.
The department must ensure that when a vendor is deleted, the system also removes each record in the Subcontract Documents table related to the vendor. If the subcontract document record has the field Posted = false, it must not be possible to delete the record.
HOTSPOT
You need to define the XML file properties for the accounting department.
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.
정답:
Question No : 15
HOTSPOT
You need to write an Upgrade codeunit and use the DataTransfer object to handle the data upgrade.
Which solution should you use for each requirement? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
정답:
Explanation:
Upgrade codeunit trigger: OnValidateUpgradePerDatabase
Since the question specifies that you are handling data upgrades, and you need to use validation before upgrading at the database level, the correct choice is OnValidateUpgradePerDatabase. This method ensures that the upgrade process is validated before applying to the entire database, making it more efficient when data affects multiple companies or structures. DataTransfer method to use: CopyRows
CopyRows is the appropriate method when you are handling large data transfers between tables, especially in an upgrade scenario where you are migrating or transferring data from one table to another. It copies entire rows of data and is optimal for bulk data operations during upgrades.
