The answer is to revoke all active sessions for the user and suspend the user account in Microsoft Defender for Cloud Apps. These two actions provide immediate containment by cutting off the compromised user’s current access and preventing any new authentication attempts, directly addressing the core risk of data exfiltration. On the SC-200 exam, this scenario tests your ability to prioritize rapid incident response over slower or less effective measures like blocking a single IP address, which can be easily bypassed by a determined attacker. A common trap is choosing to run a full scan or report to Microsoft, but those are post-containment steps, not immediate actions. Remember the containment mnemonic: “Cut and Lock” — cut sessions, lock the account.
SC-200 Respond to security incidents Practice Question
This SC-200 practice question tests your understanding of respond to security incidents. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which TWO actions should be taken to respond to a potential data exfiltration incident detected by Microsoft Defender for Cloud Apps?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Suspend the user account in Microsoft Entra ID.
Suspending the user account and revoking active sessions are immediate containment actions. Blocking IP is good but may not be sufficient if the user is compromised. Reporting to Microsoft is not immediate. Running a full scan is not for cloud apps.
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.
✗
Block the IP address of the user's device at the firewall.
Why it's wrong here
Blocking IP addresses may be useful but is not as direct as suspending the account; the user could use another device.
✓
Suspend the user account in Microsoft Entra ID.
Why this is correct
Suspending the account stops the user from accessing any cloud apps immediately.

✗
Report the user to Microsoft for investigation.
Why it's wrong here
This is not an immediate response action.
✓
Revoke all active sessions for the user in Defender for Cloud Apps.
Why this is correct
Revoking sessions forces the user to reauthenticate and stops ongoing exfiltration.

✗
Run a full antivirus scan on the user's device.
Why it's wrong here
Not relevant to cloud app exfiltration; the device may not be involved.
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.

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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
