Which Azure messaging service supports the AMQP protocol and provides enterprise-grade guaranteed message delivery with queues and topics?
Answer: Azure Service Bus
Azure Service Bus supports AMQP 1.0 and provides enterprise messaging with queues and topics/subscriptions for guaranteed, ordered delivery.
Which Azure service is best suited for reactive, event-based architectures where you need to route events from Azure services to event handlers?
Answer: Azure Event Grid
Azure Event Grid is designed for event-driven architectures, routing events from sources like Azure Blob Storage to handlers like Azure Functions using a publish-subscribe model.
What Azure Service Bus feature allows you to process related messages in a guaranteed order by a single consumer?
Answer: Message sessions
Message sessions enable ordered, exclusive processing of related message sequences by locking a session-aware consumer to messages sharing the same session ID.
In Azure Event Hubs, what is a 'consumer group'?
Answer: A view of the entire event hub that enables multiple consuming applications to read the stream independently
A consumer group is a view of an entire Event Hub that allows multiple consuming applications to each read the event stream at their own pace and offset independently.
Which Azure messaging service is designed for high-throughput data streaming and telemetry ingestion, such as IoT device data?
Answer: Azure Event Hubs
Azure Event Hubs is optimized for high-throughput data streaming scenarios like telemetry ingestion, capable of handling millions of events per second.
In Azure Service Bus, which feature provides a secondary sub-queue where messages are sent after exceeding the maximum delivery count?
Answer: Dead-letter queue
The dead-letter queue (DLQ) is a secondary sub-queue that automatically receives messages that exceed the maximum delivery count or are explicitly dead-lettered by the consumer.
What delivery model does Azure Event Grid use when sending events to subscribers?
Answer: Push model with configurable retry policies
Event Grid uses a push model where events are actively pushed to registered subscriber endpoints with configurable retry policies to handle delivery failures.
