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.
You plan to call a web service by using the data type HttpClient from a Business Central AL extension
You must provide the following implementation for the web service call:
* The web service must authenticate the client with a certificate.
* The certificate must include a password.
* The password must be hidden when you debug the code
You need to include the certificate in the web service call. Which instruction should you use?
ou plan to call a web service using HttpClient from a Business Central AL extension. The web service must authenticate using a certificate that includes a password, and the password must be hidden during debugging.
Options
The question asks for the correct implementation where the certificate and password are provided and where the password is hidden when debugging.
SecretText is a special data type in Business Central that hides sensitive data (like passwords) during debugging.
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question set might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear on the review screen.
A company creates a Business Central app and a table named MyTable to store records when sales orders are posted.
Users report the following issues:
* The users receive permission errors related to MyTable.
* Users are no longer able to post sales orders since installing the new app.
* The users cannot access the list page created in MyTable.
You need to resolve the user issues without creating new permission sets. You must use the principle of least privilege.
Solution: Decorate the event subscriber used for inserting data in MyTable by entering (lnherentPermissions(PermissionOb]ectType:TableData. Database:MyTable. 'R')]
Does the solution meet the goal?
Using InherentPermissions in an event subscriber with the specified syntax could potentially resolve the permission issues related to MyTable, provided that the permissions specified (in this case, 'R' for Read) align with the minimum necessary for the users to perform their tasks. This approach allows the app to grant permissions dynamically based on the context of the event subscriber, which in this case is involved with inserting data into MyTable. By granting Read permission at the event level, it ensures that users have the necessary permissions to interact with MyTable in the context of the operations facilitated by the event subscriber, without needing to alter existing permission sets or grant broader permissions than necessary. This solution adheres to the principle of least privilege by ensuring that permissions are granted only within the narrow scope needed for specific operations, thereby potentially resolving the reported user issues in a secure and controlled manner.
You need to allow debugging in an extension to view the source code. In which file should you specify the value of the allowDebugging property?
To enable debugging in an extension and allow the source code to be viewed, the allowDebugging property should be specified in the app.json file (C). The app.json file serves as the manifest for an AL project in Microsoft Dynamics 365 Business Central, defining the project's properties, dependencies, and features. By setting the allowDebugging property to true in this file, developers enable the debugging of the extension's source code, facilitating troubleshooting and development. This is essential for analyzing the behavior of the extension and identifying issues during the development process.
A company uses Business Central Users in DepartmentA are assigned a base application permission set.
The company observes that Departments can display a critical page that should be unavailable to the department.
You need to resolve the system control issue.
What should you do?
Permission sets control access to objects (such as pages, tables, reports) in Business Central. By creating a new permission set that specifically excludes the critical table (or page) and assigning this permission set to the users in Department A, you can prevent them from accessing the page.
Option A (creating a different role center page) is incorrect because role centers control the user interface, but do not directly restrict access to specific pages or tables.
Option B and Option C (extending the base application permission set) are not the best options because extending permission sets typically involves adding permissions, not removing access. The question requires restricting access to a critical page, so simply including or excluding permission sets won't solve the issue at the table or page level.
Option D (creating an entitlement object) is not relevant here, as entitlements are used in more complex licensing scenarios or environments.
Summary:
Creating a permission set object that specifically excludes access to the critical table or page and assigning it to the users will solve the problem effectively.
