The Salesforce Salesforce-MuleSoft-Developer-II Exam, Question by Question
Salesforce Certified MuleSoft Developer II is an official exam run by Salesforce / MuleSoft under exam code Salesforce-MuleSoft-Developer-II. Passing it awards the Salesforce Certified MuleSoft Developer II certification, which sits at the Professional / Advanced Developer tier. It also counts toward related credentials such as Salesforce Certified MuleSoft Developer I, MuleSoft Certified Integration Architect. Certified professionals remain in shorter supply than the market wants, which is precisely why this exam keeps showing up in conversations about better roles and better pay.
The Salesforce Certified MuleSoft Developer II exam gives you 120 minutes to work through 60 (plus up to 5 unscored items) questions. That is a tight ratio, and it punishes candidates who get emotionally attached to any single item. The fix is mechanical: answer what you know, flag what you do not, and keep moving. A few full-length timed runs in the Actual4Exams test engine, with its randomized question order, will calibrate your pace far better than untimed reading ever could.
The official fee for Salesforce Certified MuleSoft Developer II is $400 USD (retake fee: $100 USD), and 70% is what passing takes. The uncomfortable part: retakes cost the full $400 USD (retake fee: $100 USD) again, which makes preparation the cheapest line item in this whole project. Before booking, put yourself through repeated scored sessions with the Actual4Exams practice tests and compare results over time; a stable margin above the passing line, not a single lucky run, is when you are ready.
