Quick Answer
The answer is a session policy. This is correct because Microsoft Defender for Cloud Apps session policies use reverse proxy architecture to intercept and control user actions in real-time, allowing you to block downloads of highly confidential files to unmanaged devices based on device state tags like "unmanaged" or "compliant." On the MS-102 exam, this question tests your ability to distinguish between policy types: access policies control sign-in conditions, activity policies trigger alerts but don’t block in real-time, and app discovery policies identify shadow IT—only session policies enforce granular, real-time download blocks. A common trap is confusing session policies with access policies, but remember: session policies act on the session itself (like downloads), while access policies act on entry (like login). Memory tip: think “Session = Screen” for real-time control, not just entry or alerts.
This MS-102 practice question tests your understanding of manage security and threats by using microsoft defender xdr. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 has Microsoft Defender for Cloud Apps (MCAS) deployed. You need to create a policy that automatically blocks downloads of files classified as 'Highly Confidential' from SharePoint Online to unmanaged devices. Which policy type should you use?
Access policy
Why wrong: Controls sign-in conditions, not file downloads.
Activity policy
Why wrong: Monitors activities but does not block in real-time.
App discovery policy
Why wrong: Identifies shadow IT, not controls file downloads.
Session policy
Uses reverse proxy to control actions in real-time.

Correct answer & explanation
Session policy
Option B is correct because session policy uses reverse proxy to monitor and control user actions in real-time, allowing blocking of downloads based on device state. Option A is wrong because access policy controls sign-in conditions, not file downloads. Option C is wrong because activity policy monitors activities but does not block in real-time. Option D is wrong because app discovery policy identifies shadow IT, not controls file downloads.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.

Variation 1. Your organization uses Microsoft Defender for Cloud Apps. You discover that a user is accessing sensitive data from an unmanaged device. You need to automatically restrict the user's access to sensitive data until the device is compliant. What should you configure?
hardWhy A: Option D is correct because session control can block access based on device compliance. Option A is wrong because it doesn't restrict access. Option B is wrong because it's for conditional access to apps. Option C is wrong because it's for discovery.
