The EX283 exam, officially titled Red Hat Certified Enterprise Microservices Developer exam, is the RedHat exam you pass to earn the Red Hat Certified Enterprise Microservices Developer certification, a credential at the Specialist / Professional level. Passing it confirms the skills defined in the official exam outline, and it is associated with related credentials such as Red Hat Certified Enterprise Application Developer (RHCEAD), Red Hat Certified JBoss Developer (RHCJD), Red Hat Certified Architect (RHCA).

The EX283 exam includes 15-20 performance-based tasks questions and gives you 150 minutes to finish them. That is a tight pace per question, so get used to reading each stem once, flagging anything uncertain, and moving on rather than getting stuck. Running timed practice tests in the Fast2test desktop or online test engine is the most reliable way to build that rhythm before exam day.

The passing score for the EX283 exam is 210 out of 300, and the official registration fee is Approx. $400 USD (varies by region). Keep in mind that a failed attempt means paying Approx. $400 USD (varies by region) again in full to retake it, so book your slot only when your scores on Fast2test practice tests sit consistently above the passing line.
