In today's fast-changing digital world, more people need to know about Microsoft 365. The MS-900 (Microsoft 365 Fundamentals) certification is key for those wanting to show they're experts in cloud computing and more. It covers cloud computing, productivity suites, and how to keep data safe in Microsoft 365.
This guide dives deep into the MS-900 certification. It helps you learn how to use Microsoft 365 confidently. It's great for IT pros, business leaders, or anyone interested in tech. You'll learn why getting the MS-900 certification is good and how to prepare for the exam.
The MS-900 (Microsoft 365 Fundamentals) focuses on SaaS productivity services like Teams, Exchange, SharePoint, and Microsoft 365 licensing, while the az-900 (Azure Fundamentals) covers core Azure cloud infrastructure, compute, storage, and networking services. Both exams contain 40-60 questions, require a passing score of 700/1000, and cost $99 USD. Candidates pursuing a broad Microsoft cloud foundation often take both, though neither is a prerequisite for the other.
If your role centers on end-user productivity, collaboration, or Microsoft 365 administration, start with MS-900; if you work with cloud infrastructure, virtual machines, or Azure services, begin with az-900. Many IT professionals complete MS-900 first because its content is more concrete and business-focused, making it an easier entry point before tackling Azure's technical depth.
Both MS-900 and az-900 share foundational cloud concepts including the shared responsibility model, cloud service types (IaaS, PaaS, SaaS), and deployment models (public, private, hybrid). They also overlap on Microsoft's trust, privacy, compliance, and identity principles, particularly around Microsoft Entra ID (formerly Azure Active Directory), which underpins both Microsoft 365 and Azure authentication.

Prepare for the MS-900 - Microsoft 365 Fundamentals Certification exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: What is the MOST effective way for new MS-900 professionals to build competency?
Answer: B. Combining formal education, mentored practice, and ongoing professional development
Explanation:
The correct answer is combining formal education, mentored practice and ongoing professional development. Each part covers a gap the others leave: courses give structure, practice with a mentor turns it into judgement, and continued learning keeps it current.
Studying certification materials exclusively is wrong because it builds recall without applying it to real situations. Learning through trial and error is wrong because mistakes go unnoticed or uncorrected without guidance, and it is slow. Focusing solely on advanced topics is wrong because it skips the fundamentals that advanced ideas rest on.
Rule to remember: when a question asks for the most effective approach, prefer the answer that combines methods over the one that relies on a single method or an extreme.
Question: When planning a project in Microsoft 365 Fundamentals Certification, which element should be established FIRST?
Answer: B. Clear objectives, scope, and success criteria
Explanation:
The correct answer is clear objectives, scope and success criteria. Until you know what the project is meant to achieve and how success will be judged, you cannot sensibly set a budget, choose people or fix a schedule.
Budget allocation is wrong as a starting point because it needs a defined scope to be realistic. Team member assignments are wrong because the skills you need depend on the goals. Project timeline is wrong because durations come from the work to be done, which the scope defines.
Rule to remember: in planning questions, the item that the other items depend on comes first. Define the what and the why before the who, how much and when.
Question: What type of technical support is included with all Microsoft 365 business and enterprise subscriptions?
Answer: B. 24/7 phone and web support for critical issues
Explanation:
The correct answer is 24/7 phone and web support for critical issues. The question describes support that comes with paid business and enterprise subscriptions, and round-the-clock access for the most serious problems is the baseline it points to.
On-site support only during business hours is wrong because it is limited in both place and time, and it does not match remote support for urgent issues. Email support only with 48-hour response times is wrong because it excludes phone and web channels and would be too slow for critical problems. Community forum access only is wrong because forums are a self-help extra, not a support entitlement.
Rule to remember: paid plans include direct support channels, and the severity of the issue affects how quickly help is expected.
Start with the official skills outline on Microsoft Learn and read the four content areas so you know what is in scope. Then take one practice set per area as a cold diagnostic, without notes, and write down every question you missed along with the reason: you did not know the term, you confused two products, or you misread the question.
Work through the weakest area next. Read the matching Microsoft Learn module, then retake that set and read each explanation, including those for questions you got right. If you guessed correctly, treat it as a miss.
The pricing, licensing and support area and the security and compliance area tend to reward careful comparison, so build a short table of similar-sounding services with one line on what each is for. The extra sets on identity and access, deployment and device management, analytics and reporting, and service health help you see how the areas connect in real situations.
In the last few days, stop learning new material. Redo the sets you missed most, practise reading questions slowly, and keep an eye on the clock, since the exam is timed. Remember that our questions are written by us with AI tools and are not real exam questions, so use them to test understanding, not to memorise answers.
