- A
Create a Conditional Access App Control session policy
Why wrong: Conditional Access App Control is the technology, but the specific policy is a session policy with conditions
- B
Create a session policy in Defender for Cloud Apps that checks for device tags and blocks download
Session policies can inspect device tags (managed/unmanaged) and block sensitive actions like downloading
- C
Create a Microsoft Purview Data Loss Prevention policy for SharePoint
Why wrong: DLP policies classify and protect data at rest or in transit, but do not provide real-time session blocking based on device management status
- D
Create a Microsoft Intune compliance policy to block unmanaged devices
Why wrong: Intune compliance policies apply to device enrollment and access, not to session-level actions within an app
Quick Answer
The answer is to create a session policy in Microsoft Defender for Cloud Apps that checks for device tags and blocks downloads. This method is correct because Defender for Cloud Apps uses reverse proxy architecture to inspect device metadata—specifically the device tag indicating managed or unmanaged status—during a live session, allowing it to enforce real-time download blocks without altering the SharePoint file itself. On the Microsoft Cybersecurity Architect exam, this scenario tests your understanding of how Conditional Access App Control works as the underlying framework, but the specific policy type you configure is the session policy; a common trap is confusing this with a Data Loss Prevention policy in Purview, which handles classification and static rules, not dynamic session-level control. To remember, think “session policy = session-level control,” and note that device tags are the key signal for distinguishing managed from unmanaged devices in real-time.
SC-100 Practice Question: Design security solutions for applications and data
This SC-100 practice question tests your understanding of design security solutions for applications and data. 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.
A company uses Microsoft Defender for Cloud Apps to control data exfiltration from sanctioned SaaS apps. Security admins want to block downloading sensitive files from SharePoint Online to unmanaged devices. Which method should be used?

Correct answer & explanation
Create a session policy in Defender for Cloud Apps that checks for device tags and blocks download
Session policy with device tag check is the correct approach because Defender for Cloud Apps can inspect device tags during a session and block downloads if the device is unmanaged. Option A is wrong because Conditional Access App Control is the underlying framework, not a specific policy type. Option B is wrong because DLP policies in Purview are for classification, not real-time blocking in apps. Option D is wrong because compliance policies are for device compliance, not session-level control.
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
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
How to think about this question
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
