Mulesoft MCD-LEVEL-2 Exam Questions & Answers

Which statement is true when working with correlation IDS?

A. The HTTP Listener regenerates correlation IDs regardless of the HTTP request

B. The Anypoint MQ Connector automatically propagates correlation IDS

C. The HTTP Listener generates correlation IDS unless a correlation ID is received in the HTTP request

D. The VM Connector does not automatically propagate correction IDs

An order processing system is composed of multiple Mule application responsible for warehouse, sales and shipping. Each application communication usingAnypoint MQ. Each message must be correlated against the original order ID for observability and tracing.

How should a developer propagate the order ID as the correlation ID across each message?

A. Use the underlying HTTP request of Anypoint MQ to set the`X-CORRELATION_ID' header to the orderID

B. Set a custom Anypoint MQ user propertyto propagate the order ID and set the correlation ID in the receiving applications.

C. Use the default correlation ID, Anypoint MQ will sutomatically propagate it.

D. Wrap all Anypoint MQ Publish operations within a With CorrelationID scope from the Tracing module, setting the correlation ID to the order ID

A Mule application includes a subflow containing a Scatter.Gather scope. Within each log of the Scatter.Gatter. an HTTP connector calls a PUT endpoint to modify records in different upstream system. The subflow is called inside an Unit successful scope to retry if a transitory exception is raised.

A technical spike is being performed to increase reliability of the Mule application.

Which steps should be performed within the Mule flow above the ensure idempontent behavior?

A. Change the PUT requests inside the Scatter-Gather to POST requests

B. Ensure an error-handling flow performs corrective actions to roll back all changes if any leg of the Scatter-Gather fails

C. Remove the Put requests from the Scatter-Getter and perform them sequentially

D. None, the flow already exhibits idempotent behavior
