Udemy gives DP-900 candidates an inexpensive, self-paced starting point. "DP-900 Microsoft Azure Data Fundamentals Certification" is one of the instructor-made video courses on the marketplace, ratings and reviews help you compare options, and eligible courses carry a 30-day refund window.
Where it differs from Edureify is feedback on your own progress. Udemy has no baseline test, readiness score or study plan that adapts to you; separately purchased practice-test courses report per-attempt scores by domain, so judging when you're ready for DP-900 stays a manual job.
On Edureify, a baseline test covers core data concepts, analytics workloads, and relational data on Azure before any studying. DP-900 is short, so the roadmap is short too: if the diagnostic shows you already know relational basics, your 20-odd hours go to analytics workloads, file formats and non-relational storage instead. Each session then updates your Readiness Score and predicted ready-by date.
