Câu 1: Salesforce Certified MuleSoft Integration Architect I

Refer to the exhibits. An Order microservice and a Fulfillment microservice are being designed to communicate with their clients through message-based integration (and NOT through API invocations). The Order microservice publishes an Order message (a kind of command message) containing the details of an order to be filled. The intent is that Order messages are only consumed by one Mule application: the Fulfillment microservice. The Fulfillment microservice consumes Order messages, fills the orders described therein, and then publishes a Fulfillment message (a kind of event message). Each Fulfillment message can be consumed by any interested Mule application, and the Order microservice is one such Mule application. What is the recommended choice of message broker(s) and message destination(s) in this scenario?

1. A. Order messages are sent to a JMS queue.Fulfillment messages are sent to a JMS topic.Both microservices interact with the same JMS provider (message broker) instance, which must therefore scale to support the load of both microservices. — đáp án hiện tại
2. B. Order messages are sent directly to the Fulfillment microservice.Fulfillment messages are sent directly to the Order microservice. The order microservice interacts with one Advanced Message Queuing Protocol (AMQP)- compatible message broker and the Fulfillment microservice interacts with a different AMQP-compatible message broker so that both message brokers can be chosen and scaled to best support redelivery to each microservice and future auditing and integrations.
3. C. Order messages are sent to an Anypoint MQ exchange.Fulfillment messages are sent to an Anypoint MQ queue.Both microservices interact with Anpoint MQ as the message broker, which must therefore scale to support the load of both microservices.
4. D. Order messages are sent to a JMS topic.Fulfillment messages are sent to a JMS queue. The Order microservice interacts with one JMS provider (message broker) and the Fulfillment microservice interacts with a different JMS provider so that both message brokers can be chosen and scaled to best support the load of each microservice.
