MuleSoft Certified Developer - Integration Professional (Mule 3) Exam

Description

MuleSoft Certified Developer - Integration Professional (Mule 3)A MuleSoft Certified Developer – Integration Professional should have extensive, real-world MuleSoft development experience and be able to develop and provide technical leadership on complex Anypoint Platform integration projects. The MCD – Integration Professional (Mule 3) exam validates that a developer has the required knowledge and skills to:

  • Create and configure flows, subflows, and flow processing strategies for reusability and performance.
  • Select and use appropriate types of transformers and modules to persist data and write MEL expressions to access and modify messages.
  • Write DataWeave expressions to transform data.
  • Control message content, flow, and processing by selecting and implementing appropriate connectors, routers, scopes, and filters.
  • Design and implement comprehensive error handling strategies for applications.
  • Implement and consume REST and SOAP web services.
  • Create and use custom Java components.
  • Use JUnit and MUnit to test Mule applications.
  • Configure and deploy Mule applications to CloudHub and/or single or clusters of customer-hosted Mule runtimes.
