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 all cloud applications being used by employees, including unsanctioned file sharing and collaboration apps. They plan to analyze traffic logs from their network firewall to identify usage patterns and assess each app's risk level. Which feature of Microsoft Defender for Cloud Apps should they enable?
Cloud Discovery uses log analysis to uncover all cloud app activity and assess risk, making it the correct feature for this scenario.
B
App Connectors
Why wrong: App Connectors use APIs to connect directly to specific cloud apps for deeper inspection and control, but they do not discover unknown apps via firewall logs.
C
Conditional Access App Control
Why wrong: Conditional Access App Control is a reverse proxy that enforces access policies on cloud apps in real time; it does not discover apps.
D
Information Protection
Why wrong: Information Protection applies classification and data loss prevention controls to data within recognized apps; it is not a discovery tool.
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 network firewalls and proxies to identify all cloud applications in use, including unsanctioned ones. It uses the Microsoft Defender for Cloud Apps catalog to assess each app's risk level based on factors like security posture, compliance certifications, and industry standards. This directly matches the scenario of discovering unsanctioned file sharing and collaboration apps from firewall logs.
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 Cloud Discovery (passive log analysis for unsanctioned app discovery) with App Connectors (active API integration for sanctioned app monitoring), leading them to choose B because they think 'connecting to apps' is needed to discover them.
Detailed technical explanation
How to think about this question
Cloud Discovery works by ingesting traffic logs via log collectors or directly from firewalls using protocols like FTP, Syslog, or API integrations. It then maps the traffic to over 31,000 cloud apps in the Defender for Cloud Apps catalog, scoring each app on over 80 risk factors such as encryption standards (e.g., TLS 1.2), data center locations, and regulatory compliance (e.g., GDPR, SOC 2). A real-world scenario is when a company discovers employees using a high-risk file-sharing app like WeTransfer, which Cloud Discovery flags due to lack of encryption at rest, allowing the security team to block it.

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.
