- A
Isolate the affected device
Isolation stops the malware from spreading.
- B
Run a full scan on the device
Full scan detects and helps remove malware.
- C
Create a custom detection rule for the malware
Why wrong: This is for future detection, not immediate response.
- D
Delete the user account
Why wrong: Deleting the account is excessive and not part of standard response.
- E
Reset the user's password
Why wrong: Password reset does not stop malware already running.

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Isolate the affected device
Options A and B are correct. Option A: Isolating the affected device immediately contains the outbreak and prevents lateral movement to other endpoints. Option B: Running a full scan ensures all malware components and artifacts are identified and removed. Option C is wrong because creating a custom detection rule is a proactive measure for future detections, not an immediate response to a confirmed outbreak. Option D is wrong because deleting the user account is extreme and does not address the malware on the device. Option E is wrong because resetting the user's password helps with credential compromise but does not stop active malware.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

Same concept, more angles
3 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. Which TWO actions should a security analyst take to contain a ransomware outbreak on a Windows server that has Microsoft Defender for Endpoint installed?
medium- ✓ A.Run a full scan with Microsoft Defender Antivirus
- B.Reset the local administrator password
- ✓ C.Initiate device isolation
- D.Uninstall Microsoft Defender for Endpoint and reinstall
- E.Restore the system from a backup
Why A: Options B and D are correct. B isolates the device to prevent lateral movement, and D runs a scan to remove the ransomware. Option A is wrong because resetting the password does not stop the ransomware. Option C is wrong because uninstalling would remove protection. Option E is wrong because a full restore might reintroduce the malware.
Variation 2. Which TWO response actions are available in Microsoft Defender for Endpoint for a compromised device? (Choose two.)
easy- A.Disable the user account
- ✓ B.Run a full antivirus scan
- C.Change the Windows Firewall rules
- ✓ D.Isolate the device from the network
- E.Reset the device to factory defaults
Why B: Options B and D are correct because Microsoft Defender for Endpoint includes predefined response actions such as running a full antivirus scan and isolating a device from the network. Option A is incorrect because disabling the user account is an identity mitigation action in Azure AD, not a device response in Defender for Endpoint. Option C is incorrect because changing Windows Firewall rules is not a standard response action in Defender for Endpoint. Option E is incorrect because resetting a device to factory defaults is not a supported response action.
Variation 3. Which TWO remediation actions are available in Microsoft Defender for Endpoint when responding to a malware infection?
hard- ✓ A.Run a full antivirus scan
- B.Disable the user account
- C.Reset the device to factory settings
- D.Block the application in Defender for Cloud Apps
- ✓ E.Isolate the device from the network
Why A: Option A is correct because Microsoft Defender for Endpoint allows running a full antivirus scan as a remediation action for malware infections. Option E is correct because isolating the device from the network is a built-in remediation action to contain the threat and prevent lateral movement. Option B is incorrect because disabling the user account is an identity-related action typically performed in Microsoft Entra ID, not within MDE's remediation capabilities. Option C is incorrect because resetting to factory settings is not a standard remediation action in MDE; it would be a post-remediation step. Option D is incorrect because blocking the application in Defender for Cloud Apps is a cloud app security control, not a remediation action within Endpoint.
