Exam DP-100 topic 2 question 82 discussion

First one is event grid https://learn.microsoft.com/en-us/azure/data-explorer/create-event-grid-connection?tabs=portal-adx%2Cportal-2 the last one is logic apps: https://learn.microsoft.com/en-us/azure/machine-learning/v1/how-to-trigger-published-pipeline?view=azureml-api-1

Event Grid, Logic Apps

Given answer seems correct. Event grid needs to be filled explicitly (by someone), it does not happen by itself. you need some kind of function. Therefore detecting whether or not there is new data can be done by a timed based triggered function which pushes an event to an event grid. Then trigger the retraining based on the event grid entry.

The other way around, 1: event grid to monitor event of new data 2: triggering functions to re-train the model

Event Hubs: Used for high-volume, streaming data ingestion. Event Grid: Used for reactive programming based on event-driven architectures, distributing event notifications.

Identify when new data is uploaded: You can use Event Grid to subscribe to events that are emitted when new data is uploaded to Azure Blob Storage. Event Grid will send an event to your subscription whenever a new blob is created or modified. Trigger re-training: Logic Apps can be a good choice for linking data to blob storage and then to ML Studio. Logic Apps are a more complex solution than Functions, but they offer more flexibility and integration capabilities. I think Logic Apps would be a better choice over Functions for triggering as the question asks for linking different services together. As far as I know, Logic Apps can be used to integrate with other Azure services, such as Azure Notification Hubs and Azure Service Bus and if we need to integrate with other Azure services, then Logic Apps may be a better choice.

Trigger re-training can be use Functions and Logic Apps. In this problem it sound like simple process so I think Functions is better than Logic Apps.

Azure Event Grid: Azure Event Grid can be used to monitor events in Azure Blob Storage. You can configure Event Grid to trigger an event when new data is uploaded to Azure Blob Storage. Azure Functions: Azure Functions is a serverless compute service that can be used to run your re-training code in response to the event triggered by Azure Event Grid. You can write your re-training logic as a function and configure it to be executed when the event is received. By combining Azure Event Grid and Azure Functions, you can create an automated re-training pipeline that triggers the re-training process whenever new data is uploaded to Azure Blob Storage, without the need for extensive coding or manual intervention.

Identify when new data is uploaded >> Event Grid Trigger re-training >> Azure Logic Apps basta 😅

Answer is reverse. you can configure Azure Blob Storage to trigger an event in Azure Event Grid when new data is uploaded. Then, you can create an Azure Function that listens for the event and initiates the re-training process

I think this is Event Grid + Event Grid?

Could also be Event Grid + Event Grid

I think this is Event Grid + Logic Apps?
