[All AZ-305 Questions]

You have an Azure subscription that contains two applications named App1 and App2. App1 is a sales processing application. When a transaction in App1 requires shipping, a message is added to an Azure Storage account queue, and then App2 listens to the queue for relevant transactions.
In the future, additional applications will be added that will process some of the shipping requests based on the specific details of the transactions.
You need to recommend a replacement for the storage account queue to ensure that each additional application will be able to read the relevant transactions.
What should you recommend?

  • A. one Azure Data Factory pipeline
  • B. multiple storage account queues
  • C. one Azure Service Bus queue
  • D. one Azure Service Bus topic

No doubt, the Service Bus Topic is exactly what you would need if multiple applications want to send messages to consumers.

Correct Answer - D: Azure Service Bus Topic - The key detail in the requirement is that in the future, multiple applications will process the shipping requests. This implies a need for a publish-subscribe model where multiple subscribers (applications) can independently process messages (transactions). - Azure Service Bus Topic: Topics in Azure Service Bus support the publish-subscribe pattern. Multiple subscribers can independently retrieve filtered or unfiltered messages from the topic. This is the best fit for the described requirement. https://learn.microsoft.com/en-us/azure/service-bus-messaging/service-bus-queues-topics-subscriptions

Selected Answer: D
D. one Azure Service Bus topic In this scenario, you should recommend using an Azure Service Bus topic. Topics provide a publish-subscribe messaging pattern that allows multiple subscribers to independently retrieve messages based on their specific needs. As you add more applications to process shipping requests, each application can subscribe to the topic and filter the messages based on the transaction details.

D is the answer. https://learn.microsoft.com/en-us/azure/service-bus-messaging/service-bus-queues-topics-subscriptions#topics-and-subscriptions A queue allows processing of a message by a single consumer. In contrast to queues, topics and subscriptions provide a one-to-many form of communication in a publish and subscribe pattern. It's useful for scaling to large numbers of recipients. Each published message is made available to each subscription registered with the topic. Publisher sends a message to a topic and one or more subscribers receive a copy of the message.

Answer is C. The shipping must be handled by only ONE receiver at a time. If you use D (Topic) several subscribers can receive the message and processes the shipment resulting in several shipments. Queue does not mean only one receiver but only ONE AT A TIME to process the message. https://medium.com/awesome-azure/azure-difference-between-azure-service-bus-queues-and-topics-comparison-azure-servicebus-queue-vs-topic-4cc97770b65 Queues Queues offer First In, First Out (FIFO) message delivery to one or more competing consumers. That is, receivers typically receive and process messages in the order in which they were added to the queue. And, only one message consumer receives and processes each message. https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-queues-topics-subscriptions

Sorry answer is D not because of having multiple consumers but because of the need of filtering based on the transaction details. Publisher sends a message to a topic and one or more subscribers receive a copy of the message, depending on filter rules set on these subscriptions.
