Exam AZ-204 topic 19 question 4 discussion

* EventId is held by class EventGridController * You can add properties to telemetry by implementing ITelemetryInitializer which defines the Initialize method. * ITelemetry.Context.Properties is correct, but shouldnt be used any more as obsoloete public class IncludeEventId : ITelemetryInitializer { public void Initialize (ITelemetry telemetry) { telemetry.Context.Properties["EventId"] = EventgridController.EventId.Value; } } https://docs.microsoft.com/en-us/azure/azure-monitor/app/api-custom-events-metrics#sampling-filtering-and-processing-telemetry https://docs.microsoft.com/en-us/dotnet/api/microsoft.applicationinsights.datacontracts.telemetrycontext.properties?view=azure-dotnet#Microsoft_ApplicationInsights_DataContracts_TelemetryContext_Properties

Box 1: ITelemetryInitializer Box 2: Initialize Box 3: Telemetry.Context Box 4: EventGridController.EventId.Value Scenario: The application reacts to events from Azure Event Grid and performs policy actions based on those events. The application must include the Event Grid Event ID field in all Application Insights telemetry. \You can add properties to telemetry by implementing ITelemetryInitializer which defines the Initialize method. https://docs.microsoft.com/en-us/azure/azure-monitor/app/api-custom-events-metrics#sampling-filtering-and-processing-telemetry

1. public class IncludeEventId: ITelemetryInitializer 2. public void Initialize (ITelemetry telemetry) 3. telemetry.Context.Properties["EventId"] 4. EventGridController.EventId.Value

Box 1: ITelemetryInitializer Box 2: Initialize Box 3: Telemetry.Context Box 4: ((EventTelemetry)telemetry).Properties["EventID"]

anyone got this case study in exam?

The given answer is correct. Box 4 is inside a function which takes in a parameter called: telemetry. The telemetry parameter, serves a purpose: to be used in the function in: ((EventTelemetry)telemetry).Properties["EventID"].

Not correct. = > Use the EventId static prop of EventgridController

How static is the content of Event Grid Event ID... I agree with atomicicebreaker, bt doubt between "IProcess, Process, Context & EventHub" and "IInitialise, Initialise, Context & EventHub"

Box #4 is ok?
