Data Factory and Synapse pipelines natively integrate with Azure Event Grid, which lets you trigger pipelines on such events. the arrival or deletion of a file in Azure Blob Storage account

c is correct

custom trigger use Event-grid

Correct. C

Correct

Correct

To trigger an Azure Data Factory pipeline when a file arrives in an Azure Data Lake Storage Gen2 container, you should enable the Microsoft.EventGrid resource provider. Microsoft.EventGrid is an event-based publish/subscribe service that allows you to easily route events between different Azure services. By subscribing to the blob-created event in an Azure Data Lake Storage Gen2 container, you can trigger an Azure Data Factory pipeline whenever a file arrives in the container. Therefore, the correct answer is C. Microsoft.EventGrid.

Usually while triggering an event using ADF, there is event-based trigger. Apart from that, ADF is well integrated with Azure Event Grid, which lets us trigger pipelines on an event.

Why it's not Microsoft.Automation?

correct

Correct.

But EventHub does not support ADLS, only Blob storage

C. is correct. You need storage event trigger (for this Microsoft.EventGrid service needs to be enabled).

Why not eventhub?
