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. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 gain visibility into the use of unsanctioned cloud applications (shadow IT) within their organization. The security team has access to network proxy logs that show traffic to various cloud services. They want to use a Microsoft security solution to analyze these logs and identify which cloud apps are being used, by whom, and how much data is being consumed. Which capability of Microsoft Defender for Cloud Apps should they use?
Why wrong: App governance focuses on managing and monitoring OAuth apps and their permissions, not on discovering unsanctioned cloud apps from traffic logs.
B
Cloud Discovery
Cloud Discovery uses log data to discover and evaluate cloud app usage, helping identify shadow IT and providing insights into usage patterns.
C
Conditional Access App Control
Why wrong: Conditional Access App Control provides real-time session control for cloud apps (e.g., blocking downloads), but does not discover shadow IT from logs.
D
App Connectors
Why wrong: App Connectors provide API-based integration with third-party cloud apps for visibility and control, but they are not used for analyzing proxy logs to discover unsanctioned apps.
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 in Microsoft Defender for Cloud Apps analyzes network proxy logs (or traffic logs from firewalls and proxies) to identify unsanctioned cloud app usage (shadow IT). It provides visibility into which cloud apps are being used, by which users, and how much data is consumed, directly matching the company's requirement to analyze logs for shadow IT detection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Conditional Access App Control
Why it's wrong here
Conditional Access App Control provides real-time session control for cloud apps (e.g., blocking downloads), but does not discover shadow IT from logs.

Why it's wrong here
App Connectors provide API-based integration with third-party cloud apps for visibility and control, but they are not used for analyzing proxy logs to discover unsanctioned apps.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse Cloud Discovery (log analysis for shadow IT discovery) with App Connectors (API-based integration for managed apps), leading them to select App Connectors because they think 'connecting' to apps is needed to see usage.
Detailed technical explanation
How to think about this question
Cloud Discovery works by ingesting traffic logs from network proxies or firewalls (e.g., in Common Log Format or W3C Extended Log Format) and then using the Defender for Cloud Apps catalog of over 31,000 cloud apps to identify and categorize the traffic. It can also integrate with Microsoft Defender for Endpoint to get direct traffic data from Windows devices, enabling user-level attribution without needing proxy logs. A subtle behavior is that Cloud Discovery can automatically generate risk scores for discovered apps based on factors like encryption, data residency, and compliance certifications.

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.
