A Flight Management System publishes gate change notification events whenever a flight's arrival gate changes. Other systems, including Baggage Handler System.

Which configuration is required in Anypoint MQ to achieve this publish/subscribe model?
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.

An API has been built to enable scheduling email provider. The front-end system does very little data entry validation, and problems have started to appear in the email that go to patients. A validate-customer'' flow is added validate the data.
What is he expected behavior of the 'validate-customer'' flow?
The validate-customer flow uses an until-successful scope to validate each field of the customer data. The until-successful scope executes its processors until they succeed or exhausts the maximum number of retries. If any processor fails, it raises an error and stops executing the remaining processors. Therefore, if only the email address is invalid, a VALIDATION.INVALID_EMAIL error is raised and the validation of appointment date and customer name is skipped.
