Câu 35: MCIA-LEVEL-1: MuleSoft Certified Integration Architect - Level 1

Refer to the exhibit. A Mule application is deployed to a multi-node Mule runtime cluster. The Mule application uses the competing consumer pattern among its cluster replicas to receive JMS messages from a JMS queue. To process each received JMS message, the following steps are performed in a flow:Step 1: The JMS Correlation ID header is read from the received JMS message. Step 2: The Mule application invokes an idempotent SOAP webservice over HTTPS, passing the JMS Correlation ID as one parameter in the SOAP request. Step 3: The response from the SOAP webservice also returns the same JMS Correlation I D. Step 4: The JMS Correlation ID received from the SOAP webservice is validated to be identical to the JMS Correlation ID received in Step 1. Step 5: The Mule application creates a response JMS message, setting the JMS Correlation ID message header to the validated JMS Correlation ID and publishes that message to a response JMS queue. Where should the Mule application store the JMS Correlation ID values received in Step 1 and Step 3 so that the validation in Step 4 can be performed, while also making the overall Mule application highly available, fault-tolerant, performant, and maintainable?

1. A. Both Correlation ID values should be stored in a persistent object store
2. B. The Correlation ID value in Step 1 should be stored in a persistent object store The Correlation ID value in Step 3 should be stored as a Mule event variable/attribute
