  Import.json-moduls
• B.Add the JSON module dependency and add the validate-schema operation in the flow, configured to reference the schema

• B.Create a dedicated endpoint that responds with the API status and health of the server
• C.Use an existing resource endpoint of the API
• D.Create a dedicated endpoint that responds with the API status only

A Mule application deployed to a standardalone Mule runtime uses VM queues to publish messages to be consumed asynchronously by another flow.
In the case of a system failure, what will happen to in-flight messages in the VM queues that have been consumed?
