Question 1

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?



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 2

You have a query object named Items Query. You write code using an Items Query query variable. You need to export the Items Query query data to a file. Which SaveAs function should you use?



Answer : D

SaveAsCsv is the correct function to export the query data to a CSV (Comma-Separated Values) file, which is a commonly used text format for data exports.

SaveAsExcel would export to an Excel file, SaveAsWord to a Word document, and SaveAsHtml to an HTML file, but since the requirement is to export to a file and the question doesn't specify any particular file format other than what fits standard data exports, CSV is the most fitting and efficient format for this scenario.

For more information, see the Query Object Functions in Business Central.


Question 3

A company has an on-premises Business Central instance named TEST The instance uses Windows authorization and a developer services port of 7149 Visual Studio Code is installed on the same server.

You create a new AL project but cannot download the symbols.

The launch json file contains the following code:

You need to download the symbols.

Which two actions should you perform? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.



Answer : A, B

You are working on an on-premises Business Central instance and unable to download symbols for a new AL project. The current configuration in launch.json does not allow you to download symbols, and you need to make corrections.

Key Points in the Scenario:

Instance name is TEST.

Developer services port is 7149.

Windows authentication is being used.

Correct Answers:

A . Change the server Instance parameter to TEST.

The serverInstance parameter must match the name of the Business Central instance, which is TEST in this scenario. You need to modify this to reflect the correct instance name.

B . Add the port: 7149 parameter.

Since the developer services are using port 7149, you need to specify this in the launch.json file by adding the port parameter with the value 7149.

Incorrect Options:

C . Change the name parameter to TEST: The name parameter is just a label and does not affect downloading symbols, so changing this won't help.

D . Change the authentication parameter to UserPassword: The authentication method is already set to Windows, which is valid for this scenario. Changing it to UserPassword is unnecessary unless specified by the system.

E . Check which server the instance is installed on and replace http://localhost with the correct IP address: Since the server is on the same machine as Visual Studio Code (as specified), localhost is correct.


Question 4

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.



Answer : B, D, E

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.


Question 5

You have a custom app.

A warning for the rule code named AAOXYZ appears in multiple app objects.

You need to change the severity of the rule from Warning to Info for only the current app.

Which three actions should you perform? Each correct answer presents part of the solution. Choose three.

NOTE: Each correct selection is worth one point.



Answer : B, F


Question 6

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?



Answer : D

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.


Question 7

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

A.

Does the solution meet the goal?
