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: B

Refer to the exhibit.

1. A. The Experience API implementation generates a correlation ID for each incoming HTTP request and passes it to the web store backend in the HTTP response, which includes it in all subsequent API invocations to the Experience APIThe Experience API implementation must be coded to also propagate the correlation ID to the Process API in a suitable HTTP request header<> ><> ><> >

1. A. EACH item VM message is processed AT MOST ONCE by ONE CloudHub worker, with workerschosen in a deterministic round-robin fashion Each of the four CloudHub workers can be expected toprocess 1/4 of the Item VM messages (about 50 items)
2. B. EACH item VM message is processed AT LEAST ONCE by ONE ARBITRARY CloudHub worker Each of the four CloudHub workers can be expected to process some item VM messages
3. C. ALL Item VM messages are processed AT LEAST ONCE by the SAME CloudHub worker where theparent flow was invokedThis one CloudHub worker processes ALL 200 item VM messages
4. D. ALL item VM messages are processed AT MOST ONCE by ONE ARBITRARY CloudHub workerThis one CloudHub worker processes ALL 200 item VM messages

Correct Answer: B

An API client is implemented as a Mule application that includes an HTTP Request operation using a
default configuration. The HTTP Request operation invokes an external API that follows standard
HTTP status code conventions, which causes the HTTP Request operation to return a 4xx status code.
What is a possible cause of this status code response?

1. A. An error occurred inside the external API implementation when processing the HTTP request thatwas received from the outbound HTTP Request operation of the Mule application
2. B. The external API reported that the API implementation has moved to a different external endpoint
3. C. The HTTP response cannot be interpreted by the HTTP Request operation of the Mule applicationafter it was received from the external API
4. D. The external API reported an error with the HTTP request that was received from the outboundHTTP Request operation of the Mule application

Correct Answer: D
