This MS-900 practice question tests your understanding of describe microsoft 365 apps and services. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses Microsoft 365 Business Premium and wants to enable secure remote access for employees using personal devices. Which Microsoft 365 app should they configure to enforce conditional access policies based on device compliance?
Microsoft Purview
Why wrong: This focuses on data governance and compliance, not device management.
Microsoft Intune
Intune manages device compliance and integrates with Entra ID for conditional access.
Microsoft Sentinel
Why wrong: This is a SIEM for security analytics, not device compliance.
Microsoft Defender for Cloud Apps
Why wrong: This is a CASB, not for device compliance.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Microsoft Intune
Microsoft Intune is the correct answer because it is the Microsoft 365 app that provides mobile device management (MDM) and mobile application management (MAM). It allows administrators to define device compliance policies (e.g., requiring encryption, PIN, or a minimum OS version) and integrate those policies with Microsoft Entra ID (formerly Azure AD) Conditional Access. When a user attempts to access corporate resources from a personal device, Conditional Access checks the device's compliance status reported by Intune before granting access.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Microsoft Sentinel
Why it's wrong here
This is a SIEM for security analytics, not device compliance.
Microsoft Defender for Cloud Apps
Why it's wrong here
This is a CASB, not for device compliance.
Common exam traps
The trap here is that candidates may confuse Microsoft Defender for Cloud Apps (a CASB) with device compliance enforcement, but Defender for Cloud Apps controls app access via session policies, not device health checks, which is Intune's role.
Detailed technical explanation
Under the hood, Intune uses the OMA-DM (Open Mobile Alliance Device Management) protocol to communicate with devices and enforce compliance settings. When a device is marked non-compliant, Intune reports this status to Microsoft Entra ID, which then enforces Conditional Access policies by blocking or limiting access (e.g., requiring multi-factor authentication or blocking email access). A real-world scenario: an employee's personal Android device lacks a screen lock; Intune marks it non-compliant, and Conditional Access prevents the user from accessing SharePoint Online until the device is remediated.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
