SC-200 Manage a security operations environment Practice Question
This SC-200 practice question tests your understanding of manage a security operations environment. 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.
Your organization uses Microsoft Defender for Endpoint and has enabled the 'Block at First Sight' feature. You notice that some legitimate executables are being blocked incorrectly. You need to temporarily allow these files while you submit them for analysis. What should you do?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an indicator of compromise (IoC) in Microsoft Defender for Endpoint to allow the file hash.
Option A is correct because creating an allow indicator (IoC) in Microsoft Defender for Endpoint explicitly overrides the cloud-based 'Block at First Sight' verdict for a specific file hash. This allows the legitimate executable to run while you submit it for analysis, without disabling the broader protection feature. The allow indicator takes precedence over automated blocking actions, providing a temporary, targeted exemption.
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.
✓
Create an indicator of compromise (IoC) in Microsoft Defender for Endpoint to allow the file hash.
Why this is correct
Allow indicators override automatic blocking for specific files.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Add an application control policy in Microsoft Intune to allow the files.
Why it's wrong here
Intune policies are not the primary method to override Defender for Endpoint blocks.
✗
Submit the files to Microsoft for analysis and wait for the verdict.
Why it's wrong here
Submitting does not immediately allow the files; they remain blocked until analysis completes.
✗
Disable the 'Block at First Sight' feature until the files are analyzed.
Why it's wrong here
Disabling the feature weakens protection and is not a targeted solution.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think disabling the feature entirely (Option D) is a quick fix, but the exam tests the understanding that targeted allow indicators are the correct, least-privilege approach to handle false positives without compromising overall security posture.
Detailed technical explanation
How to think about this question
Under the hood, 'Block at First Sight' uses cloud-based machine learning models to evaluate files in near real-time; an allow indicator with a file hash creates a custom detection rule that is evaluated before the cloud lookup, effectively whitelisting the hash in the Defender for Endpoint engine. This mechanism relies on the IoC's priority in the evaluation chain—allow indicators are processed first, then block indicators, then cloud verdicts. In a real-world scenario, this is critical for preventing false positives from disrupting business-critical applications while maintaining protection against unknown threats.

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.
