What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST API's, Anypoint CLI or the Mule Maven plugin?

1. A. By default, the Anypoint CLI and Mule Maven plugin are not included in the Mule runtime
2. B. Access to Anypoint Platform API;s and Anypoint CLI can be controlled separately thruough the roles and permissions in Anypoint platform, so that specific users can get access to Anypoint CLI while others get access to the platform API's
3. C. Anypoint Platform API's can only automate interactions with CloudHub while the Mule maven plugin is required for deployment to customer hosted Mule runtimes
4. D. API policies can be applied to the Anypoint platform API's so that only certain LOS's has access to specific functions

Correct Answer: A
Correct answer is By default, the Anypoint CLI and Mule Maven plugin are not included in the Mule runtime Maven is not part of runtime though it is part of studio. You do not need it to deploy in order to deploy your app. Same is the case with CLI.

An API has been updated in Anypoint Exchange by its API producer from version 3.1.1 to 3.2.0 following accepted semantic versioning practices and the changes have been communicated via the API's public portal. The API endpoint does NOT change in the new version. How should the developer of an API client respond to this change?

1. A. The update should be identified as a project risk and full regression testing of the functionality that uses this API should be run.
2. B. The API producer should be contacted to understand the change to existing functionality.
3. C. The API producer should be requested to run the old version in parallel with the new one.
4. D. The API client code ONLY needs to be changed if it needs to take advantage of new features.

Correct Answer: D
* Semantic Versioning is a 3-component number in the format of X.Y.Z, where : X stands for a major version.
Y stands for a minor version:
Z stands for a patch.
So, SemVer is of the form Major.Minor.Patch Coming to our question , minor version of the API has been changed which is backward compatible. Hence there is no change required on API client end. If they want to make use of new featured that have been added as a part of minor version change they may need to change code at their end. Hence correct answer is The API client code ONLY needs to be changed if it needs to take advantage of new features.

An organization if struggling frequent plugin version upgrades and external plugin project dependencies. The team wants to minimize the impact on applications by creating best practices that will define a set of default dependencies across all new and in progress projects.
How can these best practices be achieved with the applications having the least amount of responsibility?

1. A. Create a Mule plugin project with all the dependencies and add it as a dependency in each application's POM.xml file
2. B. Create a mule domain project with all the dependencies define in its POM.xml file and add each application to the domain Project
3. C. Add all dependencies in each application's POM.xml file
4. D. Create a parent POM of all the required dependencies and reference each in each application's POM.xml file

Correct Answer: D

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

Correct Answer: D

An organization is designing an integration solution to replicate financial transaction data from a legacy system into a data warehouse (DWH).
The DWH must contain a daily snapshot of financial transactions, to be delivered as a CSV file. Daily transaction volume exceeds tens of millions of records, with significant spikes in volume during popular shopping periods.
What is the most appropriate integration style for an integration solution that meets the organization's current requirements?

1. A. Event-driven architecture
2. B. Microservice architecture
3. C. API-led connectivity
4. D. Batch-triggered ETL

Correct Answer: D
Correct answer is Batch-triggered ETL Within a Mule application, batch processing provides a construct for asynchronously processing larger-than-memory data sets that are split into individual records. Batch jobs allow for the description of a reliable process that automatically splits up source data and stores it into persistent queues, which makes it possible to process large data sets while providing reliability. In the event that the application is redeployed or Mule crashes, the job execution is able to resume at the point it stopped.
