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?
Answer(s): B
· 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
A company is designing an integration Mule application to process orders by submitting them to a back-end system for offline processing. Each order will be received by the Mule application through an HTTP5 POST and must be acknowledged immediately.Once acknowledged the order will be submitted to a back-end system. Orders that cannot be successfully submitted due to the rejections from the back-end system will need to be processed manually (outside the banking system).The mule application will be deployed to a customer hosted runtime and will be able to use anexisting ActiveMQ broker if needed. The ActiveMQ broker is located inside the organization's firewall. The back-end system has a track record of unreliability due to both minor network connectivity issues and longer outages.Which combination of Mule application components and ActiveMQ queues are required to ensure automatic submission of orders to the back-end system while supporting but minimizing manual order processing?
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?
Answer(s): A
Mule 4 is built to:· Minimize the need for custom code.· Avoid the need for you to know or understand Java.However, some advanced uses cases require integration with custom Java code, such as:· Reuse of a library, such as a tax calculation library. · Reuse of a canonical object model that is standard in the organization.· Execution of custom logic using Java.Mule ref doc : https://docs.mulesoft.com/java-module/1.2/
An organization is building a test suite for their applications using m-unit. The integration architect has recommended using test recorder in studio to record the processing flows and then configure unit tests based on the capture eventsWhat are the two considerations that must be kept in mind while using test recorder (Choose two answers)
Answer(s): A,D
A corporation has deployed multiple mule applications implementing various public and private API's to different cloudhub workers. These API's arc Critical applications that must be highly available and in line with the reliability SLA as defined by stakeholders. How can API availability (liveliness or readiness) be monitored so that Ops team receives outage notifications?
