Question 1

An organization currently uses a multi-node Mule runtime deployment model within their datacenter, so each Mule runtime hosts several Mule applications. The organization is planning to transition to a deployment model based on Docker containers in a Kubernetes cluster. The organization has already created a standard Docker image containing a Mule runtime and all required dependencies (including a JVM), but excluding the Mule application itself. What is an expected outcome of this transition to container-based Mule application deployments?

Options :

A : Required redesign of Mule applications to follow microservice architecture principles

B : Required migration to the Docker and Kubernetes-based Anypoint Platform - Private Cloud Edition

C : Required change to the URL endpoints used by clients to send requests to the Mule applications

D : Guaranteed consistency of execution environments across all deployments of a Mule application

Answer: A

Question 2

According to MuleSoft, a synchronous invocation of a RESTful API using HTTP to get an individual customer record from a single system is an example of which system integration interaction pattern?

Options :

A : Request-Reply

B : Multicast

C : Batch

D : One-way

Answer: A

Question 3

An organization has implemented the cluster with two customer hosted Mule runtimes is hosting an application. This application has a flow with a JMS listener configured to consume messages from a queue destination. As an integration architect can you advise which JMS listener configuration must be used to receive messages in all the nodes of the cluster?

Options :

A : Use the parameter primaryNodeOnly= "false" on the JMS listener

B : Use the parameter primaryNodeOnly= "false" on the JMS listener with a shared subscription

C : Use the parameter primaryNodeOnly= "true" on the JMS listener with a nonshared subscription

D : Use the parameter primaryNodeOnly= "true" on the JMS listener

Answer: B

Question 4

A company is implementing a new Mule application that supports a set of critical functions driven by a rest API enabled, claims payment rules engine hosted on oracle ERP. As designed the mule application requires many data transformation operations as it performs its batch processing logic. The company wants to leverage and reuse as many of its existing java-based capabilities (classes, objects, data model etc.) as possible What approach should be considered when implementing required data mappings and transformations between Mule application and Oracle ERP in the new Mule application?

Options :

A :

Create a new metadata RAML classes in Mule from the appropriate Java objects and then perform transformations via Dataweave

B : From the mule application, transform via theXSLT model

C : Transform by calling any suitable Java class from Dataweave

D :

Invoke any of the appropriate Java methods directly, create metadata RAML classes and then perform required transformations via Dataweave

Answer: C

Question 5

A Mule application is deployed to a cluster of two(2) cusomter-hosted Mule runtimes. Currently the node name Alice is the primary node and node named bob is the secondary node. The mule application has a flow that polls a directory on a file system for new files. The primary node Alice fails for an hour and then restarted. After the Alice node completely restarts, from what node are the files polled, and what node is now the primary node for the cluster?

Options :

A :

Files are polled from Alice node Alice is now the primary node

B :

Files are polled form Bob node Alice is now the primary node

C :

Files are polled from Alice node Bob is the now the primary node

D :

Files are polled form Bob node Bob is now the primary node
