The answer is to configure the session policy action as 'Block' and enable 'Notify user' with a customized message. This is correct because a session policy in Microsoft Defender for Cloud Apps applies real-time access and session controls to SaaS traffic, allowing you to block downloads from SharePoint Online to unmanaged devices while simultaneously requiring user acknowledgment of the policy violation through the notification prompt. On the SC-200 exam, this scenario tests your understanding of how session policies differ from access policies—access policies block sign-ins, while session policies control actions within an active session. A common trap is selecting 'Block' alone without enabling the notification, which would stop the download but fail to meet the requirement for user acknowledgment. Remember the mnemonic "Block and Talk" to recall that blocking must be paired with a notification to satisfy the full intent of the policy.
SC-200 Manage a security operations environment Practice Question
This SC-200 practice question tests your understanding of manage a security operations environment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 uses Microsoft Defender for Cloud Apps to monitor SaaS applications. You discover that a user is downloading a large number of files from SharePoint Online to an unmanaged device. You need to automatically block the download and require the user to acknowledge a policy violation. Which action should you configure in a session policy?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the action to 'Block' and enable 'Notify user' with a customized message.
Option C is correct because a session policy in Microsoft Defender for Cloud Apps can enforce real-time controls on SaaS app traffic. Setting the action to 'Block' stops the download immediately, and enabling 'Notify user' with a customized message both blocks the action and requires the user to acknowledge the policy violation, satisfying the requirement to automatically block and obtain acknowledgment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Set the action to 'Monitor only'.
Why it's wrong here
Incorrect. Monitor only does not block the download.
✗
Set the action to 'Redirect to Microsoft Entra ID conditional access'.
Why it's wrong here
Incorrect. Redirect is for MFA or device compliance, not for blocking downloads.
✓
Set the action to 'Block' and enable 'Notify user' with a customized message.
Why this is correct
Correct. Block stops the download and Notify user sends a message to acknowledge.

✗

Why it's wrong here
Incorrect. Block without notification does not require acknowledgment.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'Custom block message' (a static notification) with 'Notify user' (which includes an interactive acknowledgment), leading them to select Option D instead of the correct Option C.
Detailed technical explanation
How to think about this question
Session policies in Defender for Cloud Apps use reverse proxy architecture to intercept and inspect traffic to SaaS apps like SharePoint Online. When 'Block' is combined with 'Notify user', the proxy injects a custom HTML page that blocks the request and presents a notification with an acknowledgment button; the user must click to acknowledge before the session can continue, ensuring compliance with data protection policies. This differs from a simple block message, which is static and non-interactive.

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.
