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 lo 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: In the MyTable object add the property InherentPermissions = Rl. Does the solution meet the goal?

Show Answer Hide Answer
Correct Answer: B

The property InherentPermissions is used to automatically grant permissions to the table object it is applied to, but setting it to Rl (which seems to be a typo and should likely be 'RL' for Read and Insert permissions) is not sufficient in this scenario. The issues reported by the users suggest that they need more than just read and insert permissions on MyTable. Since users are unable to post sales orders, they likely need Modify, Delete, or Execute permissions on certain tables or objects related to the sales order process. Additionally, the inability to access the list page created in MyTable could be due to lacking Read permissions on other related objects or pages. Therefore, merely setting InherentPermissions = RL on MyTable does not comprehensively address the users' permission issues, especially when considering the principle of least privilege. A more tailored approach to permissions, potentially involving adjustments to the app's code or configuration to ensure proper permissions are applied where necessary, would be needed.

Question No. 3

A company uses Business Central.

You plan to help users through the installation process by using Assisted Setup.

You need to create a wizard page.

Which two actions should you perform? Each correct answer presents a complete solution.

NOTE: Each correct selection is worth one point.

Show Answer Hide Answer
Correct Answer: A, B

A: In Business Central, wizard pages are created using the NavigatePage type because it allows step-by-step navigation, which is perfect for wizard-like user experiences.

B: The group control organizes the content for each step in the guide, and it's essential to add these controls to the layout's Content area for each step of the wizard.

C: Worksheet is used for pages designed to handle larger datasets, not for wizard or step-by-step flows.

D: Repeater controls are used for displaying multiple records, not for guiding users through steps, so it's incorrect for this scenario.

Question No. 4

You need to access the RoomsAPI API from the canvas app.

What should you do?

Show Answer Hide Answer
Correct Answer: C

API Publishing for Extensions:

In Business Central, when creating custom APIs like RoomsAPI, it is important to ensure that they are automatically published during the installation or upgrade of the extension.

To achieve this, you can include a codeunit of type Install in the extension that explicitly publishes the custom API (RoomsAPI) as a web service. This ensures that it is available for use immediately after the extension is deployed without requiring manual intervention.

Codeunit Type:

A codeunit of type Install runs when the extension is installed or upgraded. This type of codeunit can be used to perform setup tasks such as publishing web services or APIs like RoomsAPI.

Why Not Other Options?

Option A (default API configuration): This would not automatically publish the RoomsAPI. Default APIs do not cover custom APIs.

Option B (enable APIs for the environment): Enabling APIs in Business Central allows the standard APIs to be used, but custom APIs still need to be manually published.

Option C (publish via Web Services page): This would work but requires manual intervention to publish RoomsAPI, which does not fulfill the requirement of automatic publishing during installation.

Question No. 5

A company plans to set up a local Business Central Development Docker container. The environment will be used for testing new project ideas.

You need to ensure that the most recent Business Central artifact URL has been selected. Which command should you use?

Show Answer Hide Answer
Correct Answer: A

To ensure the most recent Business Central artifact URL is selected for setting up a local Business Central Development Docker container, the command to use is Get-BcArtifactUrl -type sandbox -select Current (A). This PowerShell command retrieves the URL for the latest available Business Central artifact for a sandbox environment, ensuring that the Docker container is set up with the most up-to-date version for testing new project ideas. The -select Current parameter is crucial as it specifies that the current, or latest, version of the artifact is to be retrieved, as opposed to selecting a version based on other criteria such as Closest, NextMinor, or NextMajor.
