Question

Drag and Drop Question You need to design an architecture to capture the creation of users and the assignment of roles. The captured data must be stored in Azure Cosmos DB. Which Azure services should you include in the design? To answer, drag the appropriate services to the correct targets. Each service may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point. Answer:

Correct arrangement

  • Azure Event Hubs
  • Azure Functions

Explanation

Azure Event Hubs is the correct service to capture user creation and role assignment events at scale, as it is a high-throughput event ingestion service designed to capture streaming data from applications and services. Azure Functions then acts as the processing layer, triggered by Event Hubs, to transform and write the captured event data into Azure Cosmos DB. This Event Hubs → Functions → Cosmos DB pattern is a standard serverless data pipeline for event-driven ingestion and storage.
