Question 1
- A company is planning to migrate its deployment environment from on-premises cluster to a Runtime Fabric (RTF) cluster. It also has a requirement to enable Mule applications deployed to a Mule runtime instance to store and share data across application replicas and restarts. How can these requirements be met?
  
  A : Anypoint object store V2 to share data between replicas in the RTF cluster
  
  B : Install the object store pod on one of the cluster nodes
  
  C : Configure Persistence Gateway in any of the servers using Mule Object Store
  
  D : Configure Persistent Gateway at the RTF
  
  Answer: A
Question 2
- 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?
  
  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 3
- An Order microservice and a Fulfillment microservice are being designed to communicate with their dients through message-based integration (and NOT through API invocations). The Order microservice publishes an Order message (a kind of command message) containing the details of an order to be fulfilled. The intention is that Order messages are only consumed by one Mute application, the Fulfillment microservice. The Fulfilment microservice consumes Order messages, fulfills the order described therein, and then publishes an OrderFulfilted message (a kind of event message). Each OrderFulfilted message can be consumed by any interested Mule application, and the Order microservice is one such Mute application. What is the most appropriate choice of message broker(s) and message destination(s) in this scenario?
  
  A :
  Order messages are sent to an Anypoint MQ exchange OrderFulfilled messages are sent to an Anypoint MQ queue Both microservices interact with Anypoint MQ as the message broker, which must therefore scale to support the load of both microservices
  
  B :
  Order messages are sent to a JMS queue. OrderFulfilled messages are sent to a JMS topic Both microservices interact with the same JMS provider (message broker) instance, which must therefore scale to support the load of both microservices
  
  C :
  Order messages are sent directly to the Fulfillment microservices. OrderFulfilled messages are sent directly to the Order microservice The Order microservice interacts with one AMQP-compatible message broker and the Fulfillment microservice interacts with a different AMQP-compatible message broker, so that both message brokers can be chosen and scaled to best support the load of each microservice
  
  D :
  Order messages are sent to a JMS queue. OrderFulfilled messages are sent to a JMS topic The Order microservice interacts with one JMS provider (message broker) and the Fulfillment microservice interacts with a different JMS provider, so that both message brokers can be chosen and scaled to best support the load of each microservice
  
  Answer: B
Question 4
- Additional nodes are being added to an existing customer-hosted Mule runtime cluster to improve performance. Mule applications deployed to this cluster are invoked by API clients through a load balancer. What is also required to carry out this change?
  
  A : A new load balancer must be provisioned to allow traffic to the new nodes in a round-robin fashion
  
  B : External monitoring tools or log aggregators must be configured to recognize the new nodes
  
  C :
  API implementations using an object store must be adjusted to recognize the new nodes and persist to them
  
  D :
  New firewall rules must be configured to accommodate communication between API clients and the new nodes
  
  Answer: B
Question 5
- According to MuleSoft's IT delivery and operating model, which approach can an organization adopt in order to reduce the frequency of IT project delivery failures?
  
  A : Decouple central IT projects from the innovation that happens within each line of business
  
  B : Adopt an enterprise data model
  
  C : Prevent technology sprawl by reducing production of API assets
  
  D : Stop scope creep by centralizing requirements-gathering
