Description

MuleSoft Certified Developer - Level 1 (Mule 4)A MuleSoft Certified Developer – Level 1 should be able to successfully work on basic Mule 4 projects with guidance and supervision. The MCD – Level 1 (Mule 4) test validates that a developer has the required knowledge and skills to design- build- test and debug- deploy- and manage basic APIs and integrations: moving from Anypoint Platform to Anypoint Studio and back. S/he should be able to:

- Use MuleSoft-hosted Anypoint Platform to take a basic API through all the steps of its lifecycle: design- build- deploy- manage- and govern.

- Use Anypoint Studio to build- test- and debug basic integrations and API implementations.

- Connect to a range of resources including databases- files- web services- SaaS applications- and JMS queues.

- Perform basic data transformations using DataWeave 2.

- Control event flow and handle errors.

- Process batch records.
