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.
An organization has users who frequently collaborate on documents across departments. They want to ensure that when a document is shared with external partners, the external users must authenticate using Azure AD credentials and cannot download or print the document. Which combination of Microsoft 365 features should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SharePoint external sharing with 'Specific people' and Microsoft Purview Information Protection with 'View Only' permission
Option C is correct because SharePoint 'Specific people' external sharing restricts access to explicitly invited users who must authenticate with Azure AD credentials, while Microsoft Purview Information Protection's 'View Only' permission prevents downloading, printing, and copying of the document. This combination meets both requirements: enforced authentication and restricted document actions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Microsoft Teams guest access and Microsoft Defender for Cloud Apps session policies
Why it's wrong here
Teams guest access does not inherently restrict download/print; Defender for Cloud Apps session policies would be an additional step.
✗
OneDrive sharing settings with 'Anyone' links and Microsoft Purview Data Loss Prevention
Why it's wrong here
'Anyone' links do not require authentication.
✓
SharePoint external sharing with 'Specific people' and Microsoft Purview Information Protection with 'View Only' permission
Why this is correct
Specific people requires authentication; View Only restricts download/print.

✗
SharePoint anonymous sharing links and Microsoft Purview Sensitivity Labels
Why it's wrong here
Anonymous sharing does not require authentication.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse SharePoint external sharing settings (which control access) with Microsoft Purview Information Protection (which controls usage rights), and mistakenly think that simply restricting sharing to 'Specific people' alone prevents download/print, or that Sensitivity Labels alone enforce authentication.
Detailed technical explanation
How to think about this question
SharePoint 'Specific people' external sharing uses Azure AD B2B collaboration to issue a guest account for each external user, ensuring authentication. Microsoft Purview Information Protection (formerly Azure Information Protection) applies Azure Rights Management (Azure RMS) encryption, where the 'View Only' usage right explicitly denies the EXTRACT, PRINT, and EDIT rights in the AD RMS policy template, enforced at the client level (e.g., Office apps) and via the Information Rights Management (IRM) service. In a real-world scenario, if a user tries to open a view-only protected document in a browser, the Office Online server enforces the policy, blocking download and print options even if the user has a local copy.

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.
