Question 1,118 of 1,639
How to Block a Malicious Process Not Detected by Antivirus Using Custom Indicators
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.
During an incident, you need to prevent a malicious process from running on all endpoints using Microsoft Defender for Endpoint. The process is not yet detected by antivirus signatures. Which action should you use?
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
✓
Add an indicator to block the process
Option B is correct because Microsoft Defender for Endpoint allows you to create custom indicators of compromise (IoCs) to block or allow specific processes, files, or behaviors. Since the malicious process is not yet detected by antivirus signatures, adding an indicator to block the process file hash or certificate is the most direct and immediate action to prevent it from running on all endpoints.
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
The trap here is that candidates often confuse 'collect investigation package' or 'Live Response' as proactive blocking tools, when in fact they are post-incident forensic or single-endpoint actions, not scalable prevention mechanisms.
Detailed technical explanation
How to think about this question
Indicators in Microsoft Defender for Endpoint can be based on file hashes (SHA256), certificates, or IP/URLs, and are enforced by the Microsoft Defender Antivirus cloud-delivered protection and the endpoint's behavior monitoring. When a block indicator is created, it is distributed via the cloud to all enrolled endpoints within minutes, and the process is terminated at the point of execution—even if the file is already in memory—by the Microsoft Defender for Endpoint's kernel-mode driver. In a real-world scenario, this is critical during a zero-day outbreak where no signature exists, allowing defenders to immediately halt a campaign based on a known malicious hash or certificate.
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.
TExam Day Tips
- 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.
