Salesforce Certified MuleSoft Developer II Sample Questions (Q24-Q29):

NEW QUESTION # 24
Two APIs are deployed to a two-node on-prem cluster. Due to a requirements change, the two APIs must communicate to exchange data asynchronously.

Answer: A

Explanation:
To communicate asynchronously between two APIs deployed to a two-node on-prem cluster, the developer can use the VM Connector if the two APIs use the same domain. The VM Connector allows passing messages between different Mule applications within a single Mule runtime instance or across different instances using shared memory or persistent storage. If two APIs are deployed under the same domain, they can share resources such as VM queues and communicate asynchronously using VM Connector operations. Reference: https://docs.mulesoft.com/mule-runtime/4.3/vm-connector https://docs.mulesoft.com/mule-runtime/4.3/shared-resources


NEW QUESTION # 25
Multiple individual Mute application need to use the Mule Maven plugin to deploy to CloudHub.
The plugin configuration should .. reused where necessary and anything project, specific should be property-based.
Where should the Mule Maven details be configured?

Answer: D

Explanation:
To reuse Mule Maven plugin configuration across multiple individual Mule applications, the developer should use a parent pom.xml file. A parent pom.xml file defines common configuration for one or more child projects that inherit from it. The developer can specify common properties and dependencies for all child projects in the parent pom.xml file, such as Mule Maven plugin configuration, and then reference them in each child project's pom.xml file using placeholders. Reference: https://docs.mulesoft.com/mule-runtime/4.3/mmp-concept#parent-pom https://maven.apache.org/guides/introduction/introduction-to-the-pom.html#Project_Inheritance


NEW QUESTION # 26
A Mule application deployed to multiple Cloudhub 2.0 replicas needs to temporarily persist large files over 10MB between flow executions, and routinely needs to query whether the file data exists on separate executions.
How can this be achieved?

Answer: D

Explanation:
To temporarily persist large files over 10MB between flow executions, and routinely query whether the file data exists on separate executions, the developer should store the contents of the file on separate storage, and store the key and location of the file object using Object Store v2. This way, the developer can avoid storing large files in memory or exceeding the size limit of Object Store v2 (10MB per object). The developer can also use Object Store v2 operations to query, retrieve, or delete the file object by its key. Reference: https://docs.mulesoft.com/object-store/osv2-faq#can-i-store-files-in-object-store-v2


NEW QUESTION # 27
A Mule application uses API autodiscovery to access and enforce policies for a RESTful implementation.

Answer: B

Explanation:
To use API autodiscovery to access and enforce policies for a RESTful implementation, flowRef must be set to the name of the flow that has HTTP listener to receive all incoming RESTful operation requests. This way, API autodiscovery can identify the API implementation and associate it with the corresponding API specification and policies in API Manager. The flow that has HTTP listener is usually the main flow that contains the APIKit Router. Reference: https://docs.mulesoft.com/api-manager/2.x/api-auto-discovery-new-concept#flowref


NEW QUESTION # 28
A Flight Management System publishes gate change notification events whenever a flight's arrival gate changes. Other systems, including Baggage Handler System. Inflight Catering System and Passenger Notifications System, must each asynchronously receive the same gate change notification to process the event according.
Which configuration is required in Anypoint MQ to achieve this publish/subscribe model?

Answer: A

Explanation:
To achieve a publish/subscribe model using Anypoint MQ, where each system receives the same gate change notification event, the developer should publish the gate change notification to an Anypoint MQ exchange, create different Anypoint MQ queues meant for each of the other subscribing systems, and bind the exchange with each of the queues. An exchange is a message routing agent that can send messages to different queues based on predefined criteria. By binding an exchange with multiple queues, each queue receives a copy of every message sent to that exchange. Therefore, each system can subscribe to its own queue and receive every gate change notification event. Reference: https://docs.mulesoft.com/anypoint-mq/3.x/anypoint-mq-exchanges
