You are developing an Azure solution to collect inventory data from thousands of stores located around the world. Each store location will send the inventory data hourly to an Azure Blob storage account for processing.
The solution must meet the following requirements:
✑ Begin processing when data is saved to Azure Blob storage.
✑ Filter data based on store location information.
✑ Trigger an Azure Logic App to process the data for output to Azure Cosmos DB.
✑ Enable high availability and geographic distribution.
✑ Allow 24-hours for retries.
✑ Implement an exponential back off data processing.
You need to configure the solution.
What should you implement? To answer, select the appropriate options in the answer area.

Shouldn't receiver be Azure service bus , we are not just sending event but also inventory data (Message type). https://docs.microsoft.com/en-us/azure/event-grid/compare-messaging-services#comparison-of-services

Also "Filter data based on store location information." indicates its a message right? Furthermore ServiceBus has the ability to filter message: https://docs.microsoft.com/en-us/azure/service-bus-messaging/topic-filters

An event handler is the place where the event is sent. The handler takes some further action to process the event. Several Azure services are automatically configured to handle events and Azure Service Bus is one of them. https://docs.microsoft.com/en-us/azure/event-grid/handler-service-bus

Indeed when you look at it from the perspective of the Event Grid the question seems answerable. Your link is good. Receiver is implicitly mentioned here: "Event sources. Currently, the following Azure services support sending events to Event Grid."

I'm going with Source -> blob storage Receiver -> Service Bus (because the data sent is not an event is just data) Handler -> logic app

Event Source: Azure Blob Storage. The inventory data from each store location is sent to an Azure Blob storage account. This is where the data originates, making it the event source. Event Receiver: Azure Event Grid. Azure Event Grid is a service that routes events based on event sources to event handlers. In this case, it would be used to trigger the processing of data when it's saved to Azure Blob Storage (based on Blob Storage events), making it the event receiver. Event Handler: Azure Logic App. The requirement is to trigger an Azure Logic App to process the data for output to Azure Cosmos DB. This makes the Azure Logic App the event handler, as it's the service that responds to the event.

Correct answers : Event Source -----> Azure Blob Storage Event Receiver ----> Azure Event Grid Event Handler -------> Azure Logic App. After the Azure Blob Storage (Event Source) receives the data, it triggers an event. Azure Event Grid (Event Receiver) is a routing service built to react to these events from Azure Blob Storage. It then directs the handling of these events to Azure Logic Apps (Event Handler) for processing and output to Azure Cosmos DB. This configuration indeed fulfills the requirements you listed

The answer is wrong. From microsoft: https://learn.microsoft.com/en-us/azure/event-grid/event-handlers The supported event handlers is logic app. And https://azure.microsoft.com/en-us/products/event-grid "Event Grid connects data sources and event handlers." So, event grid is the receiver and logic app is the event handler. By elimination, az storage is the event source.

Event Grid is a fully-managed event routing service and the first of its kind. Azure Event Grid greatly simplifies the development of event-based applications and simplifies the creation of serverless workflows. Using a single service, Azure Event Grid manages all routing of events from any source, to any destination, for any application.

I think that the right solution should be: Source -> blob storage Receiver -> event grid Handler -> logic app Because: 1)the source of the event, which means WHO has created the event and who is publishing this event, is the Blob Storage 2)The receiver of this event, which means who should receive this event, is the Event Grid. In the event Grid we can create Topic. Topic is where all publishers write messages --> so the Blob Storage write into a topic which is inside an Event Grid. 3)Handler of this event, which means who should handle this event, is the Logic App by creating a subscription in the event grid and connecting the Logic App to that subscription.
