Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Defender for Cloud Apps
Microsoft Defender for Cloud Apps is the correct component because it is specifically designed to provide visibility into shadow IT and enforce policies on cloud applications. Its 'Governance' actions include blocking downloads from risky apps by integrating with the cloud app's API to prevent data exfiltration, which directly addresses the requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Microsoft Defender for Endpoint
Why it's wrong here
Defender for Endpoint protects devices from malware and attacks but does not control cloud app usage.
✗
Microsoft Defender for Identity
Why it's wrong here
Defender for Identity monitors on-premises Active Directory for identity-based attacks.
✗
Microsoft Defender for Office 365
Why it's wrong here
Defender for Office 365 secures email and collaboration tools like SharePoint and Teams, not third-party cloud apps.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Microsoft Defender for Cloud Apps with Microsoft Defender for Office 365, assuming that Office 365's data loss prevention (DLP) covers all cloud apps, but DLP in Office 365 is limited to Microsoft 365 services, not third-party shadow IT apps.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft Defender for Cloud Apps uses the Cloud App Security Broker (CASB) model, connecting to cloud apps via their REST APIs to enforce policies like 'block download' as a governance action. This leverages app permissions to intercept and deny download requests in real time, often using conditional access app control (with Azure AD) to redirect traffic for session-level monitoring. A real-world scenario is blocking downloads from a newly discovered file-sharing app like Dropbox to prevent data leakage, while still allowing access for viewing.

→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.
