Summary
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.
