A solutions architect is designing a messaging solution where multiple independent backend services need to process the same order event, each performing a different task (e.g., send an email, update inventory, generate an invoice). Which Azure messaging pattern should the architect recommend to ensure each service receives its own copy of the event?

Azure Service Bus topic with multiple subscriptions

Azure Event Grid with a single subscriber

A company is modernizing a legacy on-premises order-processing system. The new solution will receive orders from a partner via a REST API, then process each order asynchronously. The processing logic is a long-running workflow that must be resilient to transient failures and must not lose messages. You need to recommend a messaging architecture that decouples the API from the processing workflow. What should you recommend?

Use Azure Relay to forward the REST API call directly to the on-premises workflow.

Use Azure Service Bus queues between the API and the workflow, with the API sending messages and the workflow consuming them.

Use Azure Event Hubs to ingest orders and have the workflow read from the event stream.

Use Azure Event Grid to deliver each order directly to the workflow via a webhook.

A healthcare company is building an event-driven system to process patient data. They have the following constraints: (1) The system must comply with data residency requirements, so all data must remain in a specific Azure region. (2) The processing must be near-real-time. (3) The team wants to use a serverless approach to minimize operational overhead. (4) They need to handle occasional large bursts of events. Which service should they use for event ingestion?

A solutions architect is designing a system where state changes in a business application (e.g., order created, payment received) need to trigger downstream processes in near real-time. The architect wants to decouple the producers from the consumers. Which Azure service is most appropriate for this event-driven architecture?
