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 SOC uses Microsoft Defender XDR. You need to create a custom detection rule that triggers when a specific process is executed on multiple devices within an hour. Which feature should you use?

Correct answer & explanation
✓
Microsoft Defender XDR custom detection rule
Microsoft Defender XDR custom detection rules are built on top of Advanced Hunting and allow you to define conditions that trigger an alert when a specific process is executed across multiple devices within a defined time window (e.g., one hour). This feature is native to Defender XDR and does not require a separate SIEM like Sentinel, making it the correct choice for creating a detection rule that operates within the Defender XDR environment.
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 Advanced Hunting (a query tool) with the custom detection rule feature (which uses Advanced Hunting queries as a foundation but is a distinct rule-creation capability), leading them to select Option A instead of D.
Detailed technical explanation
How to think about this question
Custom detection rules in Microsoft Defender XDR use Kusto Query Language (KQL) to define conditions, and they can aggregate events across devices using the `DeviceProcessEvents` table. The rule can be configured with a time window (e.g., 1 hour) and a threshold (e.g., more than 5 devices) to trigger an alert, which is then surfaced in the Microsoft 365 Defender portal. This approach is more efficient than running ad-hoc Advanced Hunting queries because it automates monitoring and alerting without manual intervention.
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.
