Question

Drag and Drop Question You have an Azure subscription that contains an Azure Service Bus named Bus1. Your company plans to deploy two Azure web apps named App1 and App2. The web apps will create messages that have the following requirements: - Each message created by App1 must be consumed by only a single consumer - Each message created by App2 will be consumed by multiple consumers. Which resource should you create for each web app? To answer, drag the appropriate resources to the correct web apps. Each resource 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

  • A Service Bus queue
  • A Service Bus topic

Explanation

A Service Bus queue is correct for App1 because queues implement point-to-point messaging, ensuring each message is delivered to and consumed by only one consumer. A Service Bus topic is correct for App2 because topics use subscriptions to deliver a copy of each message to multiple consumers (publish-subscribe pattern), making it ideal for scenarios where multiple consumers need to process the same message independently. These are the two core Azure Service Bus messaging patterns designed specifically for these scenarios.
