MuleSoft Certified Integration Architect - Level 1 MAINTENANCE Questions and Answers

Question 1

A Mule application uses APIkit for SOAP to implement a SOAP web service. The Mule application has been deployed to a CloudHub worker in a testing environment.

The integration testing team wants to use a SOAP client to perform Integration testing. To carry out the integration tests, the integration team must obtain the interface definition for the SOAP web service.

What is the most idiomatic (used for its intended purpose) way for the integration testing team to obtain the interface definition for the deployed SOAP web service in order to perform integration testing with the SOAP client?

Options:

A.

Retrieve the OpenAPI Specification file(s) from API Manager

B.

Retrieve the WSDL file(s) from the deployed Mule application

C.

Retrieve the RAML file(s) from the deployed Mule application

D.

Retrieve the XML file(s) from Runtime Manager

Question 2

To implement predictive maintenance on its machinery equipment, ACME Tractors has installed thousands of IoT sensors that will send data for each machinery asset as sequences of JMS messages, in near real-time, to a JMS queue named SENSOR_DATA on a JMS server. The Mule application contains a JMS Listener operation configured to receive incoming messages from the JMS servers SENSOR_DATA JMS queue. The Mule application persists each received JMS message, then sends a transformed version of the corresponding Mule event to the machinery equipment back-end systems.

The Mule application will be deployed to a multi-node, customer-hosted Mule runtime cluster. Under normal conditions, each JMS message should be processed exactly once.

How should the JMS Listener be configured to maximize performance and concurrent message processing of the JMS queue?

B.

Set numberOfConsumers = 1

Set primaryNodeOnly = true

D.

Dealer D1 can use AUTO acknowledgement and dealer D2 must use manual acknowledgement and acknowledge the message

after successful processing

Question 7

An API implementation is being developed to expose data from a production database via HTTP requests. The API implementation executes a database SELECT statement that is dynamically created based upon data received from each incoming HTTP request. The developers are planning to use various types of testing to make sure the Mule application works as expected, can handle specific workloads, and behaves correctly from an API consumer perspective.

Integration testing

C.

Functional testing (black box)

D.

Performance testing
