Microsoft 365 Certified: Administrator Expert (MS-102) Practice Test

This certification targets experienced IT professionals already working as Microsoft 365 administrators who serve as the integrating hub across all Microsoft 365 workloads. Ideal candidates coordinate with architects and workload-specific administrators responsible for infrastructure, identity, security, compliance, endpoints, and applications in enterprise environments.

Typical job titles pursuing this certification include Microsoft 365 Administrator, Cloud Administrator, Identity and Access Administrator, and IT Manager overseeing Microsoft cloud services. Candidates are expected to have hands-on administration experience with at least one Microsoft 365 workload — such as Exchange Online, Teams, SharePoint, or Endpoint Management — and functional familiarity with all workloads. Working knowledge of networking fundamentals, Active Directory Domain Services, DNS, and PowerShell scripting is also expected.

To earn the Microsoft 365 Certified: Administrator Expert credential, candidates must first hold at least one qualifying Microsoft associate-level certification. Accepted prerequisites include: Microsoft 365 Certified: Endpoint Administrator Associate, Microsoft 365 Certified: Messaging Administrator Associate, Microsoft 365 Certified: Teams Administrator Associate, Microsoft Certified: Identity and Access Administrator Associate, or Microsoft Certified: Information Protection and Compliance Administrator Associate. At least one of these must be obtained before the expert certification can be awarded upon passing MS-102.

Beyond formal certification prerequisites, candidates should have practical experience administering Microsoft 365 and Microsoft Entra ID in production or lab environments. Recommended technical knowledge includes hybrid identity synchronization (Microsoft Entra Connect Sync or Cloud Sync), PowerShell-based administration, Microsoft Defender security tools, and Microsoft Purview compliance solutions. Familiarity with DNS configuration, Active Directory, and enterprise networking concepts is strongly advised.

MS-102 is a proctored exam delivered through Pearson VUE, available both online and at authorized testing centers. The exam has a time limit of 120 minutes and requires a passing score of 700 on a scale of 100–1000. Question count typically ranges from 40–60 items, though the exact number varies per exam form. Question types include scenario-based multiple-choice (single and multiple answer), drag-and-drop, build-list/reorder, and active screen (lab simulations may appear).

The exam is available in English, Chinese (Simplified), German, Spanish, French, Japanese, and Portuguese (Brazil). Candidates taking a non-English version may receive 30 additional minutes. The certification is valid for one year and can be renewed annually at no cost by passing a free, unproctored online renewal assessment on Microsoft Learn. Microsoft's standard retake policy applies: 24-hour wait after the first failed attempt, 14-day wait for subsequent attempts, with a maximum of five attempts per exam in any 12-month period.
