Salesforce Certified MuleSoft Developer Exam Prep Questions

About the Salesforce Certified MuleSoft Developer Exam

The Salesforce Certified MuleSoft Developer exam targets professionals who’ve worked on basic Mule 4 projects with guidance or supervision.

A certified MuleSoft Developer can design, build, test, debug, deploy, and manage basic APIs and integrations, moving between Anypoint Platform and Anypoint Studio as needed.

This certification is a prerequisite for the Salesforce MuleSoft Developer II credential.

Candidate Profile: Knowledge & Skills

Successful candidates are able to:

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

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

• Connect to databases, files, web services, SaaS apps, and JMS queues.

• Perform basic DataWeave 2.0 transformations, control event flow, handle errors, and process batch records.

Out of Scope (Not Expected)

This exam does not require you to:

• Implement production-ready Mule integrations in a DevOps environment.

• Expose production-ready Anypoint Platform–managed APIs from Mule apps.

• Build maintainable, modular applications and Maven builds for large-scale projects.

• Implement monitoring for Mule apps.

• Optimize for performance and reliability.

• Secure data at rest and in transit.

Typical Job Roles

• Developer

• Architect

• Administrator
