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?

  1. Set numberOfConsumers = 1
    Set primaryNodeOnly = false
  2. Set numberOfConsumers = 1
    Set primaryNodeOnly = true
  3. Set numberOfConsumers to a value greater than one
    Set primaryNodeOnly = true
  4. Set numberOfConsumers to a value greater than one
    Set primaryNodeOnly = false

A Mule application is synchronizing customer data between two different database systems.

What is the main benefit of using eXtended Architecture (XA) transactions over local transactions to synchronize these two different database systems?

  1. An XA transaction synchronizes the database systems with the least amount of Mule configuration or coding
  2. An XA transaction handles the largest number of requests in the shortest time
  3. An XA transaction automatically rolls back operations against both database systems if any operation falls
  4. An XA transaction writes to both database systems as fast as possible

Answer(s): B

An organization has implemented a continuous integration (CI) lifecycle that promotes Mule applications through code, build, and test stages. To standardize the organization's CI journey, a new dependency control approach is being designed to store artifacts that include information such as dependencies, versioning, and build promotions.

To implement these process improvements, the organization will now require developers to maintain all dependencies related to Mule application code in a shared location.

What is the most idiomatic (used for its intended purpose) type of system the organization should use in a shared location to standardize all dependencies related to Mule application code?

  1. A MuleSoft-managed repository at repository.mulesoft.org
  2. A binary artifact repository
  3. API Community Manager
  4. The Anypoint Object Store service at cloudhub.io

Answer(s): C



An organization has deployed both Mule and non-Mule API implementations to integrate its customer and order management systems. All the APIs are available to REST clients on the public internet.

The organization wants to monitor these APIs by running health checks: for example, to determine if an API can properly accept and process requests. The organization does not have subscriptions to any external monitoring tools and also does not want to extend its IT footprint.

What Anypoint Platform feature provides the most idiomatic (used for its intended purpose) way to monitor the availability of both the Mule and the non-Mule API implementations?

  1. API Functional Monitoring
  2. Runtime Manager
  3. API Manager
  4. Anypoint Visualizer
