Frequently Asked Questions
Is the MS-900 certification worth it?
Yes, especially if you are transitioning into IT, working in tech sales, or managing a team. It provides a recognized baseline of cloud knowledge that is highly valued by employers moving to M365.
Do I need coding experience for the MS-900?
No. The MS-900 is strictly a conceptual and administrative fundamentals exam. There is no PowerShell or coding required.
What is the difference between MS-900 and AZ-900?
AZ-900 focuses on Microsoft Azure (IaaS and PaaS services like virtual machines, databases, and networking). MS-900 focuses on Microsoft 365 (SaaS applications like Teams, SharePoint, and Office apps).
How long is the MS-900 certification valid?
Like all Microsoft fundamentals certifications, the MS-900 does not expire. Once you earn it, it is valid for life.
Free Practice Questions & Detailed Rationale
Question 1: Cloud Concepts
Your company wants to migrate to a cloud solution where Microsoft is responsible for managing the physical infrastructure, the operating system, and the application software. Your company will only manage the data and access policies. Which cloud service model does this describe?
A. Infrastructure as a Service (IaaS)
B. Platform as a Service (PaaS)
C. Software as a Service (SaaS)
D. Database as a Service (DBaaS)
Answer: C
Explanation: In a Software as a Service (SaaS) model, the cloud provider hosts and manages the entire application stack, including hardware, OS, and software updates. Microsoft 365 is a prime example of a SaaS solution. Customers are only responsible for their data, devices, and user identities. In IaaS or PaaS, the customer manages the OS or the application code, respectively.
Question 2: Core M365 Services
Your organization needs a centralized location where employees can chat, hold video meetings, share files, and integrate third-party applications. Which Microsoft 365 service should you recommend?
A. Microsoft Exchange Online
B. Microsoft SharePoint Online
C. Microsoft Teams
D. Microsoft Intune
Answer: C
Explanation: Microsoft Teams is the hub for teamwork in Microsoft 365. It brings together chat, video meetings, calling, and file sharing into a single application. While SharePoint is used for document storage behind the scenes, Teams provides the unified user interface for collaboration.
Question 3: Security & Compliance
You need to ensure that users can only access Microsoft 365 services if they are logging in from a compliant corporate device and are physically located within the United States. What should you configure?
A. Microsoft Purview Data Lifecycle Management
B. Microsoft Entra Conditional Access
C. Microsoft Defender for Endpoint
D. Multi-Factor Authentication (MFA) standalone
Answer: B
Explanation: Conditional Access in Microsoft Entra ID (formerly Azure AD) evaluates “signals” (such as user location, device compliance state, and risk level) to make an access decision. If a user tries to log in from outside the US or from an unmanaged device, Conditional Access policies can block the authentication attempt entirely.
Question 4: Device Management
Your company has a “Bring Your Own Device” (BYOD) policy. You need to prevent employees from copying corporate data from their Outlook app and pasting it into their personal social media apps on their personal mobile phones. Which service provides this capability?
A. Microsoft Intune (Mobile Application Management)
B. Microsoft SharePoint Online
C. Azure Virtual Desktop
D. Microsoft Defender for Office 365
Answer: A
Explanation: Microsoft Intune provides Mobile Application Management (MAM) through App Protection Policies. These policies allow you to control corporate data at the application level on personal devices without taking full control of the user’s phone. You can restrict actions like copy/paste, save-as, or screen capture between corporate and personal apps.
Question 5: Pricing and Lifecycle
You are reviewing the lifecycle of Microsoft 365 features. A new feature has just been released for initial testing and feedback, but it is not yet fully supported by Microsoft Support and may change before final release. What is this phase called?
A. General Availability (GA)
B. Public Preview
C. Targeted Release
D. End of Life (EoL)
Answer: B
Explanation: Public Preview is the phase where Microsoft releases new features to a broad audience for evaluation and feedback. Features in Public Preview are not covered by standard SLAs and might not have official support. Once a feature is finalized and fully supported, it moves to General Availability (GA).
