MS-900 Describe Microsoft 365 apps and services Practice Question
This MS-900 practice question tests your understanding of describe microsoft 365 apps and services. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 user reports that they cannot access their email on their mobile device. The IT administrator suspects a device compliance issue. Which Microsoft 365 service can the administrator use to check the device's compliance status?
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 tool because it is the mobile device management (MDM) and mobile application management (MAM) component of Microsoft 365. It allows administrators to define compliance policies (e.g., requiring encryption, a minimum OS version, or a healthy device attestation) and then check a device's compliance status in real time. When a device is non-compliant, Intune can block access to corporate resources like email, which matches the user's reported issue.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the Microsoft Purview compliance portal (which handles regulatory compliance and data protection) with device compliance (which is a mobile device management function handled exclusively by Intune).
Detailed technical explanation
How to think about this question
Under the hood, Intune uses the Device Management Enrollment Protocol (DMEP) and Open Mobile Alliance (OMA) DM to apply compliance policies to devices. When a device attempts to access Exchange Online, Azure AD Conditional Access evaluates the device's compliance status (reported by Intune) and either grants or blocks access. In a real-world scenario, if a device is jailbroken or lacks a PIN, Intune marks it as non-compliant, and the user sees an access denied message with a link to the Company Portal to remediate.
KKey Concepts to Remember

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
