- A
Delete the confidential documents from SharePoint
Why wrong: Deleting files destroys evidence.
- B
Suspend the user account in Microsoft Entra ID
Suspending the account stops the download immediately.

How to Immediately Contain a Compromised User Account in Microsoft Defender for Cloud Apps
This SC-200 practice question tests your understanding of respond to security incidents. 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 uses Microsoft Defender for Cloud Apps and Microsoft Sentinel. An alert indicates that an external IP address is downloading large amounts of data from a SharePoint site containing confidential documents. The activity is coming from a valid user account that appears to be compromised. What should you do first to stop the data exfiltration?

Correct answer & explanation
✓
Suspend the user account in Microsoft Entra ID
The first priority is to immediately stop the ongoing data exfiltration by suspending the compromised user account in Microsoft Entra ID. This disables the attacker's access via that account, halting the download. Blocking the external IP address (Option C) is less effective because the attacker could switch IPs. Changing SharePoint permissions (Option D) or deleting documents (Option A) would not stop the current download session as quickly as suspending the account.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related SC-200 ACL questions on filtering logic and placement.

Same concept, more angles
2 more ways this is tested on SC-200
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Your organization uses Microsoft Defender for Cloud Apps. You discover that a user has been accessing sensitive data from an anonymous IP address. The user's account appears to be compromised. You need to prevent further data exfiltration. What should you do?
medium- A.Disable the user account in Microsoft Entra ID.
- B.Create an IP range policy in Defender for Cloud Apps to block the anonymous IP.
- C.Change the user's password and revoke sessions.
- ✓ D.Suspend the user in Microsoft Defender for Cloud Apps.
Why D: The correct answer is D because suspending the user in Microsoft Defender for Cloud Apps immediately blocks all access to cloud apps monitored by Defender for Cloud Apps, preventing further data exfiltration. Option A is incorrect because disabling the user account in Microsoft Entra ID is a broader action that may affect access to all Microsoft services, but it is not as immediate for cloud app access and does not directly stop an ongoing exfiltration through Defender for Cloud Apps. Option B is incorrect because creating an IP range policy to block the anonymous IP address would only block that specific IP, but the attacker could easily switch to a different IP, and it does not address the compromised user account. Option C is incorrect because changing the user's password and revoking sessions may not stop data exfiltration if the attacker has already established persistent access or if the sessions are not fully terminated; suspending the user in Defender for Cloud Apps is a more direct and effective method to stop access to cloud apps.
Variation 2. You are investigating a suspicious sign-in reported in Microsoft Defender for Cloud Apps. The activity shows that a user accessed a sensitive SharePoint site from an anonymous IP address. What is the most effective immediate response to prevent further access?
medium- ✓ A.Suspend the user account in Microsoft 365 Defender.
- B.Change the SharePoint site permissions to remove the user's access.
- C.Disable the user's device in Microsoft Intune.
- D.Add the anonymous IP address to the blocked IP address list in Conditional Access.
Why A: Option A is correct because suspending the user account immediately blocks access to all cloud apps, including SharePoint, regardless of the device or IP address. Option B is incorrect because changing permissions on the SharePoint site only restricts that specific site, but the compromised user account can still access other resources. Option C is incorrect because disabling the device does not prevent the attacker from using another device to access cloud services as the compromised user. Option D is incorrect because blocking the anonymous IP address may not be effective if the attacker rotates IPs or uses a different anonymous IP, and it does not address the underlying compromise of the user account.
