A company uses Business Central online and wants to send telemetry to their own Azure Application Insights resource. They have already created the resource and obtained the connection string. What must they do in the Business Central administration center to start receiving telemetry?

Create a telemetry profile in the extension

Set the instrumentation key in the app.json manifest

Enable the 'Send telemetry to Microsoft' toggle

Enter the connection string in the Application Insights connection string field for the environment

As a key-value pair in the customDimensions parameter of LogMessage()

As a field in the eventId parameter

A partner is setting up telemetry for a customer with multiple environments. The customer wants to minimize costs while still being able to troubleshoot production issues. They also want to track custom events for a new feature. What is the most cost-effective approach?

Enable telemetry for all environments with full data retention

Disable telemetry and rely on user reports

Use a separate Application Insights resource for each environment

Enable telemetry only for the production environment and use sampling to reduce volume

A support engineer is analyzing telemetry to find the root cause of a recurring error in a specific codeunit. The error occurs intermittently and is not reproducible. The telemetry shows the error message but not the call stack. What should the engineer do to get more information?

Enable the 'Call stack' telemetry flag in the Telemetry Configuration page.

Use the built-in error telemetry that includes the full call stack.

Ask the user to reproduce the error and capture a debugger trace.

Add custom telemetry in the codeunit to log the values of key variables at the point of failure.

A developer wants to track the duration of a specific process in AL and send it as a custom telemetry signal. They have already started a stopwatch. What should they do to send the duration?

Use the GlobalLanguage() method to format the duration

Write the duration to a text file

Call LogMessage() with the duration as a custom dimension

Use the StrMenu() function to display the duration
