AZ-104 Microsoft Azure Administrator — Complete Exam Prep vs Master Microsoft Azure Fundamentals: AZ-900 Exam Prep

The course is aligned to the five official AZ-104 exam domains: managing Azure Identities and Governance (Azure Entra ID, RBAC, subscriptions, resource groups), implementing and managing Storage (Blob, File, SAS tokens, lifecycle policies, backup), deploying and managing Compute Resources (virtual machines, scale sets, App Services, containers), implementing and managing Virtual Networking (VNets, NSGs, load balancers, VPN gateways), and monitoring and maintaining Azure Resources (Azure Monitor, Log Analytics, backups, alerts). The V6.0 May 2025 update added practice exam content, refreshed the Microsoft Entra ID modules, and expanded Azure Web Apps coverage. The curriculum totals approximately 17.5 hours of on-demand video — substantial enough to cover every exam objective at meaningful depth without the padding that inflates cheaper courses. Eleven downloadable resources and a free study guide PDF supplement the video content. The bonus "last-minute exam cram" is a three-hour focused review session specifically praised by learners who used it the day before their scheduled exam. The content limitation most frequently cited by learners is a structural consequence of Azure's continuous update cycle: Microsoft regularly changes the Azure portal interface, and some lab walkthroughs demonstrate configurations in interface versions that no longer match the current portal. Learners report that the underlying concepts remain accurate — the lab steps just require adaptation to the current UI when steps do not match.

Scott Duffy is a software architect and Microsoft Azure MVP (Most Valuable Professional) with the MVP award held continuously from 2022 to 2025. He has accumulated 1.5 million total students across his Udemy catalogue, making him one of the platform's most-enrolled cloud computing instructors. His background as a software architect rather than a pure trainer gives the course a practitioner's perspective — he explains architectural trade-offs and design rationale rather than simply narrating portal clicks. Learner feedback consistently describes Duffy as "well organized," with one opencourser.com review noting he "clarified a lot of issues in the first few lectures" in a way that set a strong conceptual foundation before moving into complex topics. His willingness to update the course repeatedly (six major versions, with V6.0 released May 2025) signals genuine investment in keeping the material current — a differentiator in a certification niche where many courses are recorded once and left to age. The criticism that appears across multiple three-star reviews is pacing: the course assumes some prior familiarity with cloud concepts, and learners who are new to Azure entirely may find some modules progress faster than they can absorb. Scott's AZ-900 (Fundamentals) course is the recommended prerequisite for those without prior Azure exposure.

The course lists at $119.99 but Udemy's promotional pricing structure means the effective purchase price is consistently $14–$15. At that price point, 17.5 hours of video plus a full practice exam, downloadable resources, a study guide PDF, and lifetime access with ongoing updates represents outstanding value in the certification preparation market. The AZ-104 certification itself costs $165 per exam attempt. A course that equips learners to pass on the first attempt — as documented by multiple first-attempt pass reports in blog coverage — has a total cost (course + exam) of approximately $180, compared to failing the exam once and retaking it ($330 total). The course's value calculation therefore extends beyond the purchase price to include avoided retake costs. The included practice exam was highlighted as a significant value addition in the V6.0 update. Prior versions required learners to purchase practice exams separately; having both preparation content and assessment in a single purchase at this price is notable. Learners who want more practice exams beyond the included set frequently cite Whizlabs or MeasureUp as well-regarded supplements at additional cost.

The AZ-104 certification maps to the Azure Administrator associate role — a job title with significant market demand across mid-size and enterprise organisations that have adopted Azure as their primary cloud platform. The course is therefore preparation for both a certification exam and a real job function. Multiple learners in blog coverage describe the course as directly applicable to their current administrative responsibilities: understanding the concepts in the networking module (VNets, NSGs, VPN gateways) is immediately useful for administrators managing Azure environments in production. The monitoring module (Azure Monitor, Log Analytics) addresses skills needed to maintain production systems rather than pass exam questions in isolation. The Malith Ileperuma documentation of passing the AZ-104 in fifteen days (studying four to six hours per day) while combining Duffy's course with hands-on Azure labs demonstrates the study pattern that produces the best outcomes: the course as conceptual framework, supplemented by actual Azure portal practice using Microsoft's free labs. Learners who only watch the videos without deploying resources in a real Azure subscription consistently report less confidence in exam and post-certification scenarios.

The course covers all AZ-900 exam domains across approximately 7.5 hours of video: cloud concepts (IaaS, PaaS, SaaS, CapEx vs. OpEx), core Azure architecture (regions, availability zones, resource groups), compute, networking, storage, databases, identity and access management, security and compliance, governance, and Azure pricing models. Matt Ouellette at Packet Pilot noted it "had well built demonstrations and labs to follow along with your free Azure account or built in labs" and "did a good job at giving you a high level overview of AZ-900." The course is updated for January 2026 exam revisions and includes Version 4.0 with re-mastered audio and updated slides. The primary content critique across sources is that 7.5 hours covers the breadth of the exam at a necessarily high level — every reviewer who mentioned it recommended pairing the course with Microsoft Learn or a dedicated practice-test package to fill the gaps the compressed runtime cannot cover in depth.

Scott Duffy is consistently described across all analyzed sources as a clear, approachable instructor who excels at making cloud concepts accessible to both technical and non-technical learners. Reddit user WayneH_nz called him "an AMAZING trainer." The Javarevisited article by javinpaul ranked Duffy's course first among AZ-900 options specifically because he "explains Azure cloud concepts in an easy-to-understand way" with "real-world examples, hands-on exercises, and quizzes." Shafath Ahmed on Medium wrote that Duffy "does a pretty good job explaining the Azure fundamental contents." No reviewer across the 26 opinions analyzed raised concerns about teaching quality, pacing, or clarity — the instructor dimension is the strongest scoring element of this course.

The course sells on Udemy during frequent sales for approximately $12–$15, which Reddit users across r/cscareerquestions, r/sysadmin, and r/AZURE cite as one of its key selling points. User The_Real_Tupac on Reddit noted "it regularly sells for $12," and user geekinuniform suggested "spending $12 for the Azure course" specifically to learn cloud terminology. For that price the course includes 7.5 hours of video, a 24-page PDF study guide, downloadable audio files for offline listening, slides, and a 50-question practice test — a bundle that multiple reviewers described as exceptional value at the sale price. Lifetime access and free updates that track exam revisions (including the January 2026 update) further strengthen the value proposition.

The course includes one 50-question practice test, which reviewers consistently describe as a useful baseline gauge but insufficient standalone exam preparation. Reddit user flam3throw3r from r/AzureCertification specifically recommended pairing it with Tutorials Dojo practice tests for more exam-representative questions. User extra_specticles on r/AZURE described watching the course first, then taking practice tests from an external source to identify weak areas. The cyber4noobs.com guide noted that optional lab add-ons are available separately but not included in the base course price. The practice material is proportionate to the course's 7.5-hour scope — it functions as orientation rather than the comprehensive drill-and-review system that Udemy's dedicated practice-test packages offer.

The AZ-900 is a fundamentals-tier exam with a passing threshold of 700/1000, and every reviewer who reported an outcome after using this course passed, many on their first attempt. Reddit user jpanda206 on r/AZURE studied for "about 3 weeks with Udemy and Microsoft Learn" and passed with a score of 790. Shafath Ahmed on Medium passed after approximately two weeks of preparation using Scott Duffy's course alongside Microsoft CLX and Microsoft Learn, completing the exam in 20 minutes of the allotted 45 and scoring above 90% on final practice runs. The cyber4noobs.com reviewer passed after one week of intensive daily study. No reviewer in the analyzed set failed after completing this course, though most credited a multi-resource approach rather than this course alone.
