Question #: 35
Topic #: 1
A Flight Management System publishes gate change notification events whenever a flight's arrival gate changes. Other systems, including Baggage Handler System. Inflight Catering System and Passenger Notifications System, must each asynchronously receive the same gate change notification to process the event according.
Which configuration is required in Anypoint MQ to achieve this publish/subscribe model?

Suggested Answer: D Vote an answer

Explanation
To achieve a publish/subscribe model using Anypoint MQ, where each system receives the same gate change notification event, the developer should publish the gate change notification to an Anypoint MQ exchange, create different Anypoint MQ queues meant for each of the other subscribing systems, and bind the exchange with each of the queues. An exchange is a message routing agent that can send messages to different queues based on predefined criteria. By binding an exchange with multiple queues, each queue receives a copy of every message sent to that exchange. Therefore, each system can subscribe to its own queue and receive every gate change notification event. References:
