MuleSoft MCD-Level-1 Exam Questions Answered
The MCD-Level-1 exam leads to the MuleSoft Certified Developer - Level 1 (Mule 4) certification from MuleSoft. It is positioned at the Associate level. The exam validates the knowledge and skills expected of candidates preparing for MuleSoft Certified Developer - Level 1 (Mule 4).
Related certifications include:

The MCD-Level-1 exam includes 60 questions and allows 120 minutes. Before test day, divide the available time by the number of questions in a timed practice set to establish a steady per-question pace. If a difficult item starts consuming too much time, mark it for review and move forward instead of losing momentum. A full timed practice session can help you decide when to move on, when to return, and how much buffer to reserve for a final check.
The passing score for MCD-Level-1 is 70%, and the official exam fee is $250 USD. Because a retake requires paying the exam fee again, use timed practice results as a readiness check before scheduling your next attempt. If your performance remains inconsistent, continue reviewing weak domains and repeat a timed session before booking the exam.
No mandatory prerequisites; recommended completion of Anypoint Platform Development: Fundamentals (Mule 4) course
