Question 1

A Mule API receives a JSON payload and updates the target system with the payload. The developer usesJSON schemas to ensure the data is valid.How can the data be validation before posting to the target system?

Options :

A : Use a DataWeave 2.09 transform operation, and at the log of the DataWeave script, add:%dw 2.0Import.json-moduls

B : Using the DataWeave if Else condition test the values of the payload against the examples included inthe schema

C : Apply the JSON Schema policy in API Manager and reference the correct schema in the policyconfiguration

D : Add the JSON module dependency and add the validate-schema operation in the flow, configured toreference the schema

C : Configure < Logger level-‘ERROR’/ > inside the VM Connector configuration

Question 4

A mule application exposes and API for creating payments. An Operations team wants to ensure that the Payment API is up and running at all times in production. Which approach should be used to test that the payment API is working in production?

Options :

A : Create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API

B : Configure the application to send health data to an external system

C : Create a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself

D : Monitor the Payment API directly sending real customer payment data

Answer: A

Question 5

A Mule application includes a subflow containing a Scatter.Gather scope. Within each log of theScatter.Gatter. an HTTP connector calls a PUT endpoint to modify records in different upstream system. Thesubflow 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?

Options :

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 theScatter-Gather fails

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

D : None, the flow already exhibits idempotent behavior
