As a part of project , existing java implementation is being migrated to Mulesoft. Business is very tight on the budget and wish to complete the project in most economical way possible.
Canonical object model using java is already a part of existing implementation. Same object model is required by mule application for a business use case. What is the best way to achieve this?

1. A. Make use of Java module
2. B. Create similar model for Mule applications
3. C. Create a custom application to read Java code and make it available for Mule application
4. D. Use Anypoint exchange

Correct Answer: A
Mule 4 is built to:
•Minimize the need for custom code.
•Avoid the need for you to know or understand Java.
However, some advanced uses cases require integration with custom Java code, such as:
•Reuse of a library, such as a tax calculation library.
•Reuse of a canonical object model that is standard in the organization.
•Execution of custom logic using Java.

An insurance company is implementing a MuleSoft API to get inventory details from the two vendors. Due to network issues, the invocations to vendor applications are getting timed-out intermittently. But the transactions are successful upon reprocessing
What is the most performant way of implementing this requirement?

1. A. Implement a scatter-gather scope to invoke the two vendor applications on two different routeUse the Until-Successful scope to implement the retry mechanism for timeout errors on each route
2. B. Implement a Choice scope to invoke the two vendor applications on two different route Use the try-catch scope to implement the retry mechanism for timeout errors on each route
3. C. Implement a For-Each scope to invoke the two vendor applicationsUse until successful scope to implement the retry mechanism for the timeout errors
4. D. Implement Round-Robin scope to invoke the two vendor applications on two different routes Use the Try-Catch scope to implement retry mechanism for timeout errors on each route

Correct Answer: A

An organization has strict unit test requirement that mandate every mule application must have an MUnit test suit with a test case defined for each flow and a minimum test coverage of 80%.
A developer is building Munit test suit for a newly developed mule application that sends API request to an
external rest API.
What is the effective approach for successfully executing the Munit tests of this new application while still achieving the required test coverage for the Munit tests?

1. A. Invoke the external endpoint of the rest API from the mule floors
2. B. Mark the rest API invocations in the Munits and then call the mocking service flow that simulates standard responses from the REST API
3. C. Mock the rest API invocation in the Munits and return a mock response for those invocations
4. D. Create a mocking service flow to simulate standard responses from the rest API and then configure the mule flows to call the marking service flow

Correct Answer: C

What Is a recommended practice when designing an integration Mule 4 application that reads a large XML payload as a stream?

1. A. The payload should be dealt with as a repeatable XML stream, which must only be traversed (iterated-over) once and CANNOT be accessed randomly from DataWeave expressions and scripts
2. B. The payload should be dealt with as an XML stream, without converting it to a single Java object (POJO)
3. C. The payload size should NOT exceed the maximum available heap memory of the Mute runtime on which the Mule application executes
4. D. The payload must be cached using a Cache scope If It Is to be sent to multiple backend systems

Correct Answer: C
If the size of the stream exceeds the maximum, a STREAM_MAXIMUM_SIZE_EXCEEDED error is raised.

Refer to the exhibit.
A Mule application is being designed to expose a SOAP web service to its clients.
What language is typically used inside the web service's interface definition to define the data structures that the web service Is expected to exchange with its clients?

1. A. WSDL
2. B. XSD
3. C. JSON Schema
4. D. RAMI

Correct Answer: B
Correct Answer XSD In this approach to developing a web service, you begin with an XML schema (XSD file) that defines XML data structures to be used as parameters and return types in the web service operations.
