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.
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.
You need to determine If you have unwanted incoming web service calls in your tenant during the last seven days.
Which two KQL queries should you use? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

A company has a task that is performed infrequently. Users often need to look up the procedure to complete the task.
The company requires a wizard that leads users through a sequence of steps to complete the task.
You need to create the page to enable the wizard creation.
Which page type should you use?
For a task that is performed infrequently and requires users to follow a sequence of steps, a wizard-like interface is ideal. In Microsoft Dynamics 365 Business Central, the NavigatePage page type (A) is best suited for this purpose. NavigatePage is designed to guide users through a series of steps or pages, allowing them to complete a task by making choices or entering data in a structured manner. This page type is often used for setup wizards, data migration tasks, or any other process that benefits from a step-by-step approach. Unlike the other page types like Card (B), RoleCenter (C), or List (D), NavigatePage specifically supports the navigation and decision-making flow required for wizard creation, making it the optimal choice for this requirement.
