Free MCD - ASSOC: MuleSoft Certified Developer - Integration and API Associate (Mule 3) Exam Questions and Answers
MCD - ASSOC: MuleSoft Certified Developer - Integration and API Associate (Mule 3) is part of Salesforce's MuleSoft credential track. Since Salesforce acquired MuleSoft these exams have run inside Salesforce's own Trailhead credentials system rather than a MuleSoft-branded one, which is why they are now listed as Salesforce Certified MuleSoft credentials. The ladder runs Integration Foundations, then Developer I and Developer II, then the Platform Architect and Integration Architect papers. Developer I is 60 closed-book questions in 120 minutes needing 70% to pass, $250, English only, and valid two years — but the architect papers differ in both length and threshold.
