SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. 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.
Your organization needs to prevent sensitive data in SharePoint Online from being shared externally. Which Microsoft Purview solution should you use?

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Data Loss Prevention (DLP)
Data Loss Prevention (DLP) is the correct Microsoft Purview solution because it is specifically designed to detect and prevent the unauthorized sharing of sensitive data, such as credit card numbers or personally identifiable information (PII), by applying policies that can block external sharing in SharePoint Online. DLP policies can be configured to scan content in real-time and enforce actions like blocking access or sending notifications when sensitive data is detected in external sharing scenarios.
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 often confuse sensitivity labels with DLP, assuming labels alone can block sharing, but labels only apply protection (e.g., encryption) and require DLP policies to enforce sharing restrictions.
Detailed technical explanation
How to think about this question
DLP policies in Microsoft Purview use deep content analysis via exact data match (EDM), machine learning classifiers, and fingerprinting to identify sensitive data types, such as SWIFT codes or health records, even if the data is obfuscated. When a DLP policy is applied to SharePoint Online, it can evaluate sharing links in real-time and automatically block the creation of external sharing links or revoke existing ones if sensitive content is detected, leveraging the Microsoft 365 Activity API for near-instant enforcement.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- 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.
