✑ 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.
