SC-200 Mitigate threats using Microsoft Sentinel Practice Question
This SC-200 practice question tests your understanding of mitigate threats using microsoft sentinel. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A SOC team uses Microsoft Sentinel. They need to correlate syslog events from on-premises firewalls with Microsoft Entra ID sign-in logs to detect VPN-based intrusions. The correlation requires joining two tables (Syslog and SigninLogs) on a common field (IP address) and running on a 10-minute schedule. Which type of analytics rule should the analyst configure?
Scheduled query rules support custom KQL queries that join multiple tables and can be scheduled at any interval, making them suitable for cross-source correlation.
B
Near-real-time (NRT) rule
Why wrong: NRT rules run near-continuously but have limitations on query complexity and are typically for simple single-table detections.
C
Fusion rule
Why wrong: Fusion rules are prebuilt for advanced multi-stage attack detection and cannot be customized with a KQL join.
D
Anomaly rule
Why wrong: Anomaly rules use built-in machine learning models and are not designed for custom KQL correlations.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Scheduled query rule
A scheduled query rule is correct because the requirement involves joining two tables (Syslog and SigninLogs) on a common field (IP address) and running on a 10-minute schedule. Scheduled query rules are designed for complex, multi-table correlations that run at fixed intervals (e.g., every 10 minutes) and can aggregate or join data across tables, making them ideal for this VPN intrusion detection scenario.
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 NRT rules with scheduled rules, but NRT rules cannot perform multi-table joins, which is explicitly required by the question's correlation of Syslog and SigninLogs.
Detailed technical explanation
How to think about this question
Scheduled query rules in Microsoft Sentinel use Kusto Query Language (KQL) to perform joins, aggregations, and lookups across tables like Syslog and SigninLogs. The 10-minute schedule is configured in the rule's 'Run query every' setting, and the query can use a time range (e.g., 'lookback 10m') to correlate events within that window. A real-world scenario might involve joining on the 'SourceIP' field from Syslog with 'IPAddress' from SigninLogs to flag users who authenticated from an IP that also triggered a firewall deny event within the same time window.
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 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.
