Frequently Asked Questions
How many questions are on the Salesforce MuleSoft Developer I exam?
Current public exam-guide mirrors align on 60 multiple-choice questions with a 120-minute testing window and a 70% passing score. Some deliveries also mention up to 5 unscored items, so practice should be built around roughly one minute and 50 seconds per scored question.
Which MuleSoft Developer I domains matter the most?
The exam is intentionally spread across 12 domains, but five 10% sections make up half of the blueprint: accessing and modifying Mule events, structuring Mule applications, using connectors, processing records, and transforming data with DataWeave. Strong candidates also stay comfortable with the 8% and 7% API, routing, error, and deployment sections because there is no true throwaway domain.
What changed for MuleSoft Developer I in 2026?
As of March 9, 2026, no brand-new public blueprint overhaul surfaced for MuleSoft Developer I, but Salesforce maintenance content keeps the credential current. The Winter 25 and Winter 26 maintenance updates emphasize Java 17 compatibility, use of Compatibility Tooling, CloudHub 2.0 and Hyperforce deployment awareness, and the broader Data Cloud to Data 360 naming change that affects ecosystem references.
Do you need another Salesforce certification first?
No formal prerequisite certification is publicly required for MuleSoft Developer I. In practice, however, candidates usually need hands-on Mule 4 experience with Anypoint Studio or Code Builder, API design in RAML, connectors, DataWeave, error handling, and CloudHub deployment basics.
How should you study for MuleSoft Developer I?
Plan for 80-140 hours across 8-12 weeks if you are building from light to moderate Mule 4 experience. Study by blueprint weight, build small API-led projects end to end, practice DataWeave and event anatomy daily, and finish with timed mixed sets that force you to distinguish similar Mule scopes, routers, connectors, and error handlers under pressure.
