Microsoft Azure IoT Developer is an official Microsoft exam, registered under the code AZ-220. A passing score earns you the Microsoft Certified: Azure IoT Developer Specialty certification, positioned at the Specialty level. The credential also connects to Microsoft Certified: Azure Developer Associate, Microsoft Certified: Azure Solutions Architect Expert, Microsoft Certified: Azure IoT Fundamentals, so it can anchor a broader certification path. Because Microsoft designs its exams around real job tasks, holding this certification signals practical skill rather than memorized theory.

Candidates face Approximately 40–60 questions inside a 120 minutes window on the Microsoft Azure IoT Developer exam. That ratio leaves little slack, which is why pacing deserves as much practice as the content itself. Learn to budget your minutes, park stubborn questions instead of wrestling them, and rehearse under a real clock: a few timed runs in the NewPassLeader test engine will make the official time limit feel routine rather than threatening.

The passing bar for Microsoft Azure IoT Developer is set at 700/1000, and registering for the exam officially costs USD $165 (varies by country/region). There is no reduced price for a second try: fail, and you pay USD $165 (varies by country/region) in full again. That makes honest self-testing the cheapest insurance available, so hold off on booking until your NewPassLeader practice scores sit clearly above the passing line, attempt after attempt.

Recommended: experience with Azure services, IoT solutions, and basic programming knowledge. Familiarity with Azure Fundamentals (AZ-900) is helpful but not required.

Vendor policies are revised from time to time, so double-check the eligibility details before registering on the official exam page.
