Udemy gives AZ-802 candidates an inexpensive, self-paced starting point. "AZ-802: Administering Windows Server" 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 AZ-802 stays a manual job.
On Edureify, a baseline test covers Active Directory Domain Services, storage and file services, and monitoring and troubleshooting before any studying. AD DS is the heaviest AZ-802 area at 20–25%, so a diagnostic that exposes gaps in FSMO roles, trusts or Group Policy pushes those to the front of your roadmap, while storage and troubleshooting get their share too. Each session then updates your Readiness Score and predicted ready-by date.
