B.  

Deactivate the API in API Manager so the Autodiscovery element will not find the application when it runs in Studio

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

Options:

A.  

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

B.  

Use the underlying HTTP request of Anypoint MQ to set the X-CORRELATION-ID header to the order ID

C.  

Set a custom Anypoint MQ user property to propagate the order ID and set the correlation ID in the receiving applications

Exhibit:

Options:

A.  

If the appointment date and customer name are invalid, a SCHEDULE:INVALID_APPOINTMENT_DATE error is raised

B.  

If only the email address is invalid, a VALIDATION:INVALID_EMAIL error is raised

C.  

If the email address is invalid, processing continues to see if the appointment date and customer name are also invalid
