質問 # 26
You need to improve performance when ticketAPI is used to analyze the POS data. What should you do?
- A. Set the AceesByPermission property to Read on the ticketAPI API page.
- B. Enable read scale-out on the Business Central database.
- C. Set the DataAccesslntent property to Readonly on the ticketAPI API page.
- D. Set the ODataReadonlyGetEnabled parameter to True in the Business Central admin center.
正解：B
解説：
Read Scale-Out:
Read scale-out is a feature in Business Central that allows you to improve performance by distributing read-only queries (such as the ones from the ticketAPI) across multiple read replicas in the cloud database. This reduces the load on the primary database and helps improve the response time for read-intensive operations, like analyzing POS data through the ticketAPI.
Data Access Intent - ReadOnly:
When enabling read scale-out, you can configure the DataAccessIntent property of APIs to be ReadOnly. This directs the system to use read replicas to handle read-only queries, which enhances performance by offloading such queries from the primary database.
Why Not Other Options?
Option A (ODataReadonlyGetEnabled): This parameter is unrelated to read scale-out and primarily affects OData services behavior, not API performance tuning.
Option B (AccessByPermission): Setting the permission to Read does not directly affect the performance. It only controls access based on user permissions.
Option D (DataAccessIntent ReadOnly): While setting this property to ReadOnly helps in read-only operations, enabling read scale-out (option C) ensures the underlying infrastructure is optimized to handle such read operations, which is the fundamental action required.

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.
質問 # 27
A company is setting up a custom telemetry trace signal to send traces on failed customer statement emails.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
正解：
解説：
Explanation:
* The telemetry trace sends custom signals to an Application Insights resource specified in the extension's app.json file and on the tenant. = YES
* Dictionary keys for the extension name and version must be specified to identify the extension during analysis. = YES
* The telemetry trace sends events to Application Insights resources set up on the tenant. = YES Telemetry in Business Central allows developers to collect custom telemetry for extensions using Application Insights. The telemetry trace is used to send custom signals to an Application Insights resource. This resource is typically specified in the app.json file of the extension and must be configured on the tenant where the extension is installed.
The use of dictionary keys for the extension name and version is a best practice to identify the extension during analysis in Application Insights. These keys can be added to the telemetry trace to ensure that when the data is collected, it's clear which extension the data is associated with.
Finally, it is correct that the telemetry trace sends events to Application Insights resources that are set up on the tenant, enabling the collection and analysis of telemetry at the tenant level.
質問 # 28

質問 # 32
A company has a Business Central online environment.
You are exporting a file from a client by using the DownloadFromStream method.
You need to create an InStream data type to send the data
Which solution should you use?
- A. Use OeatelnStream method for BLOB field of "TempBlob" table.
- B. Use OeatelnStream method from codeunit "Temp Blob".
- C. Use CreatelnStream method for File type variable.
正解：B
解説：
When exporting a file from a client using the DownloadFromStream method in a Business Central online environment, you need to create an InStream data type to send the data. The solution is to use the CreateInStream method from codeunit "Temp Blob" (A). The Temp Blob codeunit provides temporary storage of BLOBs (Binary Large Objects) and is commonly used for handling files and streams in Business Central. By using the CreateInStream method on a Temp Blob, you create an InStream that can then be used with the DownloadFromStream method to send the file data to the client. This approach is efficient for file handling and transfer in Business Central, especially in scenarios involving data export or file manipulation.
質問 # 33
You create the following Vendor table and Item table in Business Central.
You require the following data set to assign vendors to items.
You need to create a query to assign the vendors.
Which three code blocks should you use to develop the solution? To answer, move the appropriate code blocks from the list of code blocks to the answer area and arrange them in the correct order.
NOTE: More than one order of answer choices is correct. You will receive credit for any of the correct orders you select.
正解：
解説：
Explanation:
To create a query that assigns vendors to items in Business Central, use the following code blocks in sequence:
* dataitem(Vendor; Vendor)
* dataitem(Item; Item)
* DataItemLink = "Vendor No." = Item.Vendor_No;
Creating a query:
In Business Central, a query object is used to combine data from multiple tables. You start by specifying each table as a data item. In this case, you would start with the Vendor table and then the Item table. After specifying the data items, you need to link them together. The DataItemLink property is used to establish a relationship between two data items based on a common field. Here, you are linking the Vendor and Item tables on the "Vendor No." field, which is present in both tables. This link ensures that the query will return a dataset that includes related records from both tables based on the vendor number. The order of the code blocks ensures the logical flow and relationships between tables as required for the query.
質問 # 34

You need to create the Install codeunit that is requited in the extension used for installing or updating the Housekeeping app.
Which data type or declaration should you use? To answer, select the appropriate options in the answer area.
NOTE; Each correct selection is worth one point.
正解：
解説：
Explanation:
For the Install codeunit required for the extension used for installing or updating the Housekeeping app, you should use the following data type and declaration:
* Data type for information: ModuleInfo
* Start of the declaration of the method or procedure to perform the tasks: local procedure In AL language, which is used for developing extensions in Business Central, an Install codeunit is a special type of codeunit that is used to handle installation or upgrade logic for an extension.
* ModuleInfo is a data type that contains information about the current extension, such as its version. It is typically used within the OnInstallAppPerCompany or OnUpgradePerCompany triggers of an Install codeunit to determine if the app is being installed for the first time or upgraded.
* A local procedure within an Install codeunit is a method that is only accessible within the codeunit itself. It is not visible to other objects or extensions. This is suitable for tasks that are internal to the installation process and should not be exposed globally.
These selections align with the requirements of handling installation and update procedures in a controlled and encapsulated manner within Business Central extensions.
Topic 1, Case Study Alpine Ski House
Alpine Ski House is a company that owns and operates hotels, restaurants, and stores. Currently, the company uses the following software and interlace:
* Property management software (PMS) to manage hotel rooms
* On-premises accounting software to generate sales invoices and create purchase orders
* An API that allows restaurants and stores to obtain necessary information Restaurants and stores use standalone software for point of sale (POS) devices. Each day, the POS terminals generate a text file of sales data and save the files in a serval folder. An account assistant must manually import the files to the current software tables to be processed by the system.
The general manager receives several reports monthly from department managers. The reports take too much time to prepare.
The company is moving from a different system to Business Central online to manage the whole company.
The company plans to increase efficiency in every department by using APIs to obtain or share information between the different systems.
Each department involved in purchasing must be able to make purchase requests automatically and easily.
The departments do not need access to the full ERP management system.
Alpine Ski House requires the development of several extensions for the planned improvements. Business Central design patterns must be used to develop all extensions.
Alpine Ski House must develop the following pages:
* Pages that provide multiple configurations in a multistep dialog, like a wizard, to provide required information when the extensions are first installed
* Department-specific Role Center pages to show relevant information and pages with additional information The IT department plans to use Power 61 to analyze departmental information. The database must be configured to provide optimal performance.
The housekeeping department requires the following to increase efficiency and help avoid data entry errors:
* A Housekeeping Role Center to minimize navigation to relevant areas In Business Central online and to show relevant information in it
* Pages to embed into a new Room page to show additional information about the Room entity
* A table named Room Incident for the housekeeping team to enter room issue information
* A Housekeeping canvas app that connects to an extension
The department requires the development of an extension with a new API page named RoomsAPI.
* The housekeeping team will use RoomsAPI to publish room details, update when work is complete, or provide repair notifications from the canvas app.
* This custom API page must expose a custom table named Rooms and have an ID 50000. The table must be able to update from the PMS. The PMS team must know the end to connect to the custom API.
* A developer provides the following details for the API page:
APIPublisher = 'alpine';
APIGroup - 'integration';
APIVersion - 'v2.6';
fntityName # 'room';
EntitySetName = 'rooms';
* The extension must be published in Business Central online and include a list page named Room List that includes all hotel rooms.
* Installation or updates to this extension must meet the following requirements:
o Some web services must be published automatically.
o The version of the specified application's metadata must be obtained in AL language.
o The code required to perform tasks cannot be accessible from other parts of the application.
The Room Incident table information must include the following fields:
* Incident entry: An incremental number
* Room No.: A room from the Room table
* Incident Date: The work date
o The table definition in the Room Incident table must autofill the Incident Date when the housekeeping team inserts a new record, o The value for Incident Date must be the work date configured in the Business Central online client.
* Status: Includes the following options lo identify the status of the incident:
o Open: When the Room Incident is created
o In Progress: When someone starts repair work
o Closed: When the incident is solved
* Incident Closing Date: Auto-updating field (when the status passes to Closed, the field will update with the work date)
* Incident Description: Text
* Image. Media data type
o The stored picture must be downloadable from a menu action.
o A Room Incident page must be developed to contain the download action.
To increase efficiency, the new system must manage the generated data from the restaurants and stores directly by using the API on the POS terminals.
* The company requires a code unit called from a job queue to read the information from the POS terminal APIs.
* The POS terminal information must be stored in a table named POS Information, have an ID 50100. and be editable on a page.
* The account manager requires an option on the menu of the page to run the process manually.
To analyze the information received from the POS terminals, the company requires:
* A custom API named ticketAPI to export the information to Power BI
* Use of the Read Scale-Out feature to improve database performance
The purchasing department requites a new entity in Business Central online to log non-conformities of goods received from vendors. The entity must be set up as follows:
* The non-conformity entity must have two tables:
o a header with common information
o one or more lines with the detailed received items that are non-conforming
* The entity requires a page named Non-conformity and a subpage named Non-Conformity Lines to store the information.
When a purchase order with incorrect quantity 01 quality issues is received, the entity must create a non- conformity document in the system. The following information must be nick the document:
* Non-conformity Number: must use the No. Series table from Business Central online to manage this field and use these features:
o Alphanumeric values
o Number format that includes "NO and the year as part of the number: for example, NC24-001
* Non-conformity Date: stores only the creation date
* Vendor No.: stores the number of the vendor that sent the items; only vendors from the company must be included
* Owner: code of an employee defined in the company
* Receipt No.: must meet the following conditions:
o Be an existing receipt No.
o Be received from the vendor indicated in the Vendor No. field
* Comments: can include comments with rich text and pictures to illustrate quality problems
* Status: includes nonconformity statuses, such as:
o Open
o Notified
o Closed
* Lines must contain the following details:
o Item No.: item received (for existing inventory items only)
o Description: item description
0 Quantity: non-conforming quantity
0 Non-conformity Type:
# Quality
# Quantity
# Delivery date
The serial numbers of the non-conformities and the period in which they can be created must be in a configuration table and its corresponding page to allow them to be modified for the users.
質問 # 38
You have a per tenant extension that contains the following code.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
正解：
解説：
Explanation:
* Codeunit "Discount Mgmt." compiles successfully. = NO
* VariantLine in line 17 must be changed to Line and the DiscountAmount removed for the codeunit to compile. = NO
* The DiscountIsValid method must be defined in the interface for the code to compile. = YES The codeunit "Discount Mgmt." will not compile successfully as is because the DiscountIsValid method is not defined in the "IDiscount Calculation" interface, yet it is being declared in the codeunit which implements this interface. AL requires that all procedures in the codeunit that implements an interface must be defined in the interface itself.
The VariantLine in line 17 does not need to be changed to Line, nor does the DiscountAmount need to be removed for the codeunit to compile. These are valid declarations in AL and they are correctly implemented in the codeunit. The Variant data type in AL is used to handle various data types and DiscountAmount is a valid return type for a procedure.
For the code to compile successfully, the DiscountIsValid method must be included in the interface because AL enforces that any codeunit implementing an interface must implement all the methods defined in that interface.
