C) Nothing, as error-level events are automatically logged
D) Configure <Logger level-'ERROR'/> inside the VM Connector configuration
2. Which pattern should be used to invoke multiple HTTP APIs in parallel and roll back failed requests in sequence?
A) A Parallel for Each scope with each HTTP request wrapped in a Try scope
B) A database as a transactional outbox and an Until Successful router to retry any requests
C) VM queues as a reliability pattern with error handlers to roll back any requests
D) Scatter-Gather as central Saga orchestrator for all API request with compensating actions for failing routes

How should a developer propagate the order ID as the correlation ID across each message?
A) Set a custom Anypoint MQ user property to propagate the order ID and set the correlation ID in the receiving applications.
B) Use the underlying HTTP request of Anypoint MQ to set the 'X-CORRELATION_ID' header to the order ID
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
5. Which statement is true when using XML SDK for creating custom message processors?
A) All operations are public
B) Operations can be reused in recursive calls
C) An XML SDK provides both inbound and outbound operations
D) Properties are fields defined by an end user of the XML SDK component and serve as a global configuration for the entire Mule project in which they are used
