Question 131

As a part of project requirement, client will send a stream of data to mule application. Payload size can vary between 10mb to 5GB. Mule application is required to transform the data and send across multiple sftp servers. Due to the cost cuttings in the organization, mule application can only be allocated one worker with size of 0.2 vCore.

As an integration architect , which streaming strategy you would suggest to handle this scenario?

In-memory non repeatable stream
In-memory non repeatable stream
File based non-repeatable stream
File based non-repeatable stream
In-memory repeatable stream
In-memory repeatable stream
File based repeatable storage
File based repeatable storage
Suggested answer: D

Explanation:

As the question says that data needs to be sent across multiple sftp serves , we cannot use nonrepeatable streams. The non-repeatable strategy disables repeatable streams, which enables you to read an input stream only once.

You cant use in memory storage because with 0.2 vcore you will get only 1 GB of heap memory.

Hence application will error out for file more than 1 GB.

Hence the correct option is file base repeatable stream

Mule application muleA deployed in cloudhub uses Object Store v2 to share data across instances. As a part of new requirement , application muleB which is deployed in same region wants to access this Object Store.

Which of the following option you would suggest which will have minimum latency in this scenario?

Object Store REST API
Object Store REST API
Object Store connector
Object Store connector
Both of the above option will have same latency
Both of the above option will have same latency
Object Store of one mule application cannot be accessed by other mule application.
Object Store of one mule application cannot be accessed by other mule application.
Suggested answer: A

Explanation:

V2 Rest API is recommended for on premise applications to access Object Store. It also comes with overhead of encryption and security of using rest api. With Object Store v2, the API call is localized to the same data center as the

Runtime Manager app.

But in this case requirement is to access the OS of other mule application and not the same mule application.

You can configure a Mule app to use the Object Store REST API to store and retrieve values from an object store in another Mule app.

However, Object Store v2 is not designed for app-to-app communication.

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?

Make use of Java module
Make use of Java module
Create similar model for Mule applications
Create similar model for Mule applications
Create a custom application to read Java code and make it available for Mule application
Create a custom application to read Java code and make it available for Mule application
Use Anypoint exchange
Use Anypoint exchange
Suggested answer: A

Explanation:

Mule 4 is built to:

ï Minimize the need for custom code.

ï Avoid the need for you to know or understand Java.

However, some advanced uses cases require integration with custom Java code, such as:

ï Reuse of a library, such as a tax calculation library.

ï Reuse of a canonical object model that is standard in the organization.

ï Execution of custom logic using Java.

In one of the critical payment related mule application, transaction is being used . As an enhancement to implementation , scatter gather route is introduced which is also the part of transaction group. Scatter gather route has 4 routes.

What will be the behavior of the Mule application in case of error occurs in 4th route of the scattergather router and transaction needs to be rolled back?

Only errored route will be rolled back
Only errored route will be rolled back
All routes will be rolled back
All routes will be rolled back
Scatter Gather router cannot be part of transaction
Scatter Gather router cannot be part of transaction
Suggested answer: B

Explanation:

ï Scatter Gather: When running within a transaction, Scatter Gather does not execute in parallel. This means that the second route is executed after the first one is processed, the third after the second one, etc. In case of error, all routes will be rolled back

Which Mulesoft feature helps users to delegate their access without sharing sensitive credentials or giving full control of accounts to 3rd parties?

Secure Scheme
Secure Scheme
client id enforcement policy
client id enforcement policy
Connected apps
Connected apps
Certificates
Certificates
Suggested answer: C

Explanation:

Connected Apps

The Connected Apps feature provides a framework that enables an external application to integrate with Anypoint Platform using APIs through OAuth 2.0 and OpenID Connect. Connected apps help users delegate their access without sharing sensitive credentials or giving full control of their accounts to third parties. Actions taken by connected apps are audited, and users can also revoke access at any time. Note that some products do not currently include client IDs in this release of the Connected Apps feature. The Connected Apps feature enables you to use secure authentication protocols and control an app's access to user data. Additionally, end users can authorize the app to access their Anypoint

Platform data.

An organization has just developed a Mule application that implements a REST API. The mule application will be deployed to a cluster of customer hosted Mule runtimes.

What additional infrastructure component must the customer provide in order to distribute inbound API requests across the Mule runtimes of the cluster?

A message broker
A message broker
An HTTP Load Balancer
An HTTP Load Balancer
A database
A database
An Object Store
An Object Store
Suggested answer: B

Explanation:

Correct answer is An HTTP Load Balancer.

Key thing to note here is that we are deploying application to customer hosted Mule runtime. This means we will need load balancer to route the requests to different instances of the cluster.

Rest all options are distractors and their requirement depends on project use case.

A mule application is deployed to a Single Cloudhub worker and the public URL appears in Runtime Manager as the APP URL. Requests are sent by external web clients over the public internet to the mule application App url. Each of these requests routed to the HTTPS Listener event source of the running Mule application. Later, the DevOps team edits some properties of this running Mule application in Runtime Manager. Immediately after the new property values are applied in runtime manager, how is the current Mule application deployment affected and how will future web client requests to the Mule application be handled?

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?
