MS-900 Practice Question: Describe security, compliance, privacy, and trust in Microsoft 365
This MS-900 practice question tests your understanding of describe security, compliance, privacy, and trust in microsoft 365. 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 wants to ensure that only IT administrators can install browser extensions in Microsoft Edge. Which Microsoft 365 security feature should be used?
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 choice because it provides mobile device management (MDM) and mobile application management (MAM) capabilities that allow administrators to configure Microsoft Edge settings via configuration profiles. Specifically, Intune can enforce the 'Installation of browser extensions' policy to restrict extension installation to IT administrators only, using the Administrative Templates for Edge within the Settings Catalog.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Conditional Access
Why it's wrong here
Conditional Access controls access to cloud apps based on conditions, not device configuration like browser extensions.
✓
Microsoft Intune
Why this is correct
Intune can manage device policies to restrict browser extension installations through configuration profiles.

✗
Microsoft Defender for Cloud Apps
Why it's wrong here
Defender for Cloud Apps is a CASB for monitoring cloud app usage, not for device configurations.
✗
Microsoft Entra ID Identity Protection
Why it's wrong here
Identity Protection detects risky sign-in behaviors, not endpoint settings.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Conditional Access (which controls access to resources) with device management policies (which control software behavior on the device), leading them to incorrectly select Conditional Access instead of Intune.
Detailed technical explanation
How to think about this question
Under the hood, Intune uses the Open Mobile Alliance (OMA) Uniform Resource Identifier (URI) protocol to push configuration service provider (CSP) policies to managed devices. For Microsoft Edge, the 'ExtensionInstallBlockList' and 'ExtensionInstallAllowList' policies are defined via the Policy CSP, allowing granular control over which extensions can be installed and by whom. In a real-world scenario, an organization might combine this with a device compliance policy to ensure only domain-joined or Intune-enrolled devices can access corporate resources, preventing unauthorized extension installations that could exfiltrate data.

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.
