Microsoft 365 Certified: Fundamentals (MS-900) Practice Test

MS-900 is designed for individuals seeking to demonstrate foundational cloud knowledge without prior deep technical expertise. Ideal candidates include IT support specialists, helpdesk technicians, junior cloud administrators, business analysts, and project coordinators who work alongside Microsoft 365 environments and want to formalize their understanding. It also suits students and career changers entering the IT field, as well as sales professionals, procurement managers, and non-technical stakeholders who need fluency in M365 capabilities to guide organizational decisions or engage with enterprise clients.

This certification serves as an on-ramp to Microsoft's broader role-based certification paths. Professionals aiming for credentials such as Microsoft 365 Administrator Expert (MS-102), Modern Desktop Administrator Associate, or Security, Compliance, and Identity Fundamentals often use MS-900 to build conceptual grounding before advancing to more technical exams.

Microsoft lists no formal prerequisites for MS-900. The exam is intentionally accessible to candidates who are new to Microsoft 365 or cloud services in general. No hands-on IT experience is required, and the exam can be taken without prior Microsoft certifications.

That said, candidates benefit most from having a basic familiarity with general IT concepts, such as the difference between on-premises and cloud environments, and some exposure to everyday Microsoft 365 tools like Outlook, Teams, or Word. Those completely new to cloud computing are advised to complete the free Microsoft Learn learning paths covering cloud concepts and Microsoft 365 services before scheduling the exam, as even foundational fluency with SaaS, IaaS, and PaaS distinctions is tested.

Exam MS-900 is a proctored assessment with a 45-minute time limit, delivered through Pearson VUE for general candidates or Certiport for students and educators. The exam may include a variety of question types such as multiple choice, drag-and-drop, and interactive scenario-based questions. Microsoft does not publish an exact fixed number of questions, but the format is consistent with other Microsoft fundamentals exams, typically ranging from 40 to 60 questions. Candidates requiring additional time due to language barriers (non-native speakers of available languages) may request an additional 30 minutes.

Scoring is on a scale of 100 to 1000, with a passing score of 700 required. If a candidate fails, a retake is permitted 24 hours after the first attempt; subsequent retakes follow Microsoft's standard retake policy with increasing wait periods. The exam is available in 12 languages: English, Japanese, Spanish, German, Chinese (Simplified), French, Korean, Portuguese (Brazil), Arabic (Saudi Arabia), Russian, Chinese (Traditional), and Italian.

• 1.Describe cloud concepts (5–10%): Covers SaaS, IaaS, and PaaS models and their Microsoft use cases; differences between Office 365 and Microsoft 365; public, private, and hybrid cloud models; cost and benefit comparisons between cloud, hybrid, and on-premises deployments; and the concept of hybrid and flexible work.
• 2.Describe Microsoft 365 apps and services (45–50%): The largest domain, covering core productivity apps (Word, Excel, PowerPoint, OneNote) and Microsoft 365 Copilot/Copilot Chat; project management tools (Project, Planner, Bookings, Forms, Lists, To Do, Loop); collaboration via SharePoint, OneDrive, Stream, Teams, Teams Phone, Exchange, Outlook, Viva apps, and Teams extensions (Whiteboard, Power Apps, Power Automate); endpoint and device management via Intune, co-management with Configuration Manager, Endpoint Analytics, Windows Autopilot, Windows Autopatch, Windows 365, and Azure Virtual Desktop; and Microsoft 365 administration capabilities including the Admin Center, user portal, and Copilot dashboard.
• 3.Describe security, compliance, privacy, and trust in Microsoft 365 (25–30%): Covers identity and access management through Microsoft Entra ID, including cloud, on-premises, and hybrid identity, MFA, SSPR, and Conditional Access; threat protection through Microsoft Defender XDR, Defender for Endpoint, Defender for Office 365, Defender for Identity, Defender for Cloud Apps, and Microsoft Secure Score; and compliance solutions including the Zero Trust Model, Microsoft Purview (insider risk, auditing, eDiscovery, sensitivity labels, data loss prevention), data residency for regulatory compliance, and Microsoft Priva.
• 4.Describe Microsoft 365 pricing, licensing, and support (10–15%): Covers pricing models for Microsoft cloud services (enterprise agreements, cloud solution providers, direct billing); billing and payment management options; license management including base and add-on licensing differences; support request processes; support tiers and options; service-level agreements (SLAs) and service credits; and checking service health status via the Microsoft 365 Admin Center or Microsoft Entra Admin Center.

• Follow the official Microsoft Learn learning paths mapped to MS-900 objectives — these free, self-paced modules are structured around the exact exam domains and are the most authoritative preparation resource available.
• Take the free official Practice Assessment on Microsoft Learn (Assessment ID 50) before and after your study period. It mirrors the actual exam's question style and difficulty and highlights specific knowledge gaps to address.
• Use the MS-900 Study Guide on Microsoft Learn to track which skills are covered by the April 30, 2025 version of the exam — pay attention to recently added topics like Microsoft 365 Copilot capabilities, Microsoft Priva, and the Copilot dashboard, as these reflect the latest update.
• Launch the Microsoft Exam Sandbox (available from the exam page) to experience the interactive question types — drag-and-drop and scenario-based items require familiarity with the interface to avoid time loss on exam day.
• Focus your heaviest study time on the 'Describe Microsoft 365 apps and services' domain (45–50%) and 'Describe security, compliance, privacy, and trust' domain (25–30%), as together they represent up to 80% of the scored content.
• For the security domain, map each Defender product (Defender for Endpoint, Defender for Office 365, Defender for Identity, Defender for Cloud Apps) to its specific threat scenario — Microsoft frequently tests candidates' ability to distinguish which tool addresses which type of threat.
• Review the Microsoft 365 Tech Community and the Exam Readiness Zone video series on Microsoft Learn for reinforcement of complex topics like Conditional Access, Microsoft Purview compliance tools, and licensing tier differences.

The MS-900 certification serves as an entry point into Microsoft's role-based certification ecosystem and signals foundational cloud literacy to employers in Microsoft 365-heavy environments. It supports career entry or transition into roles such as IT Support Specialist, Junior Cloud Administrator, Technical Support Engineer, M365 Systems Administrator, and technology-facing business roles including sales engineering and IT procurement. According to ZipRecruiter data, professionals in Microsoft 365-related roles earn an average of approximately $85,000 per year in the US, with entry-level positions ranging from $45,000 to $65,000 and junior administrator roles reaching $55,000 to $80,000. MS-900 holders who pair the credential with a role-based certification such as MS-102 (Microsoft 365 Administrator) report salary increases of 12–18%.

Although MS-900 is a foundational credential and does not independently qualify candidates for senior technical roles, it provides a meaningful career launchpad. It is a natural prerequisite stepping stone toward Microsoft Certified: Microsoft 365 Administrator Expert, Microsoft 365 Endpoint Administrator Associate, and Security, Compliance, and Identity Fundamentals. Candidates should note that the exam retires on March 31, 2026, after which Microsoft is expected to introduce updated AI-focused fundamentals credentials as part of its certification refresh initiative.
