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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 security team wants to discover which cloud applications (such as Dropbox, Salesforce, or unsanctioned file-sharing apps) are being used by employees, even if those apps are not sanctioned by IT. They need to analyze usage patterns, risk levels, and identify potential shadow IT. Which feature of Microsoft Defender for Cloud Apps should they enable?
Why wrong: App Connectors connect to cloud apps via APIs for deep visibility and control, but require the app to be known and connected; they are not the primary tool for discovering unknown apps.
B
Cloud Discovery
Cloud Discovery uses traffic logs to identify all cloud apps in use, providing a comprehensive view of shadow IT.
C
Conditional Access App Control
Why wrong: Conditional Access App Control enforces session policies on managed apps but does not discover unmanaged or unknown apps.
D
Microsoft Defender for Endpoint
Why wrong: Defender for Endpoint provides endpoint detection and response but is not designed to discover cloud app usage across the organization.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cloud Discovery
Cloud Discovery is the correct feature because it analyzes traffic logs from firewalls and proxies to identify cloud app usage, including unsanctioned apps like Dropbox or Salesforce, without requiring API integration. It provides risk scores, usage patterns, and shadow IT detection by comparing discovered apps against Microsoft's cloud app catalog of over 31,000 apps.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
✗
App Connectors (API connectors)
Why it's wrong here
App Connectors connect to cloud apps via APIs for deep visibility and control, but require the app to be known and connected; they are not the primary tool for discovering unknown apps.
✓
Cloud Discovery
Why this is correct
Cloud Discovery uses traffic logs to identify all cloud apps in use, providing a comprehensive view of shadow IT.

✗
Conditional Access App Control
Why it's wrong here
Conditional Access App Control enforces session policies on managed apps but does not discover unmanaged or unknown apps.
✗
Microsoft Defender for Endpoint
Why it's wrong here
Defender for Endpoint provides endpoint detection and response but is not designed to discover cloud app usage across the organization.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Cloud Discovery (passive log analysis for unsanctioned apps) with App Connectors (active API integration for sanctioned apps), assuming both can discover shadow IT, but only Cloud Discovery identifies apps not already connected via API.
Detailed technical explanation
How to think about this question
Cloud Discovery works by ingesting log files from network proxies or firewalls (e.g., via FTP or syslog) and using the Cloud App Catalog to fingerprint app traffic based on destination IPs, domains, and HTTP headers. It can also integrate with Microsoft Defender for Endpoint to collect traffic from Windows 10/11 devices, enabling agentless discovery of cloud app usage even without a proxy. The risk score is calculated using over 80 risk factors, including regulatory compliance, data encryption, and user base.
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.
