You need to configure telemetry for the SaaS tenant and test whether the ingested signals are displayed.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Correct Answer:
Explanation:
The correct sequence of actions to configure telemetry for the SaaS tenant and test whether the ingested signals are displayed would be:
* Create an Azure Application Insights instance by using the Azure Portal in the Customer's subscription.
* Select the environment in the Admin Center and place the connection string in the Application Insights Connection String field.
* Select the Application Insights instance, select Logs and then inspect the Traces table.
To set up telemetry for a SaaS tenant using Azure Application Insights, you need to follow these steps:
* Create an Azure Application Insights instance: This is the first step where you create an instance in Azure that will collect the telemetry data. This should be done in the customer's Azure subscription because it's their data that you're monitoring.
* Configure the SaaS tenant to use the created Application Insights instance: This involves entering the correct connection string in the Business Central Admin Center so that telemetry data from the tenant is sent to the Application Insights instance.
* Verify that telemetry is being collected: After configuring, you would check if the telemetry is arriving as expected by inspecting the Traces table in the Azure Application Insights instance. The 'Traces' table holds the telemetry data, which you can query to verify that the correct signals are being ingested.

You develop a table named Contoso Setup and a page.
You plan to use No. Series to automatically assign a unique number to data entries. You set up No. Series on the Vendor Nos. field of the Contoso Setup table.
You need to apply the No. Series Design Pattern to the trigger Onlnsert().
Which four code segments should you use to develop the solution? To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.

You need to apply the No. Series Design Pattern to the trigger Onlnsert().
Which four code segments should you use to develop the solution? To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.
Correct Answer:
Explanation:
Here is the correct sequence of the four code segments:
* if "No." = '' then begin
* ContosoSetup.Get();
* ContosoSetup.TestField("Vendor Nos.");
* NoSeriesManagement.InitSeries(ContosoSetup."Vendor Nos.", xRec."No. Series", 0D, "No.", "No.
Series"); end;
* Check for empty value: The standard pattern for OnInsert is to only assign a number automatically if the user has not manually entered one. Therefore, you start with if "No." = '' then begin.
* Retrieve Setup: You must retrieve the setup record to access the configured No. Series code. The singleton pattern for setup tables uses ContosoSetup.Get();.
* Verify Configuration: Before attempting to use the series code, best practice dictates you ensure it is actually populated in the setup table. ContosoSetup.TestField("Vendor Nos."); checks this field.
* Initialize Series: Finally, you call the InitSeries function.
* Argument 1 (Source): ContosoSetup."Vendor Nos." is the field containing the Series Code (as stated in the prompt).
* Argument 2 (Previous): xRec."No. Series" handles standard renaming/validation logic.
* Argument 4 & 5 (Targets): "No." and "No. Series" are the fields on the current record being updated.
* Note: The other available InitSeries block is incorrect because it tries to read a field named "No.
Series" from the ContosoSetup table, which does not match the prompt's description.

You need to create the configuration table and page for the non-conformity functionality.

Which table configurations should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point
Correct Answer:
Explanation:
Design pattern for the setup table:
* The correct selection here is Adapter. The Adapter design pattern is commonly used when you need to handle integration points or create a setup table that acts as an intermediary for data manipulation, which fits the requirement for the configuration of the non-conformity functionality.
Data type of the primary key field:
* The correct data type is Code. In Business Central, when creating a table with a primary key field, the Code data type is typically used for fields such as document numbers, codes, and identifiers. For a setup table, a Code field is appropriate for keys like "No." series or setup identifiers.
Property required to prevent users from adding records:
* The correct property is InitValue. This property is used to set initial values for fields and can be configured in such a way that users are prevented from adding records directly, typically enforcing control over record creation and editing in configuration scenarios.
