Full question →hardmultiple choiceObjective-mapped
A security operations center (SOC) receives a high volume of low-fidelity alerts from various security tools. They need a solution that can automatically correlate alerts into incidents, use built-in machine learning to reduce false positives, and provide a unified console for investigation and response across Azure, on-premises, and Microsoft 365. Which Microsoft security solution should they use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Microsoft Defender for Cloud
While it provides security posture and threat protection, it does not correlate alerts from multiple disparate sources into a single incident like a full SIEM.
B
Best answer
Microsoft Sentinel
Sentinel is a SIEM/SOAR that correlates alerts, reduces noise with ML, and provides a unified investigation and response console.
C
Distractor review
Microsoft Defender for Endpoint
This solution focuses on endpoint detection and response, not ingesting and correlating alerts from multiple non-endpoint sources.
D
Distractor review
Microsoft Defender for Cloud Apps
This is for cloud app security (discovery, DLP, shadow IT), not for unifying alerts from various security tools across the organization.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this SC-900 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Microsoft Sentinel — Microsoft Sentinel is a cloud-native Security Information and Event Management (SIEM) and Security Orchestration Automated Response (SOAR) solution. It ingests data from multiple sources, uses machine learning to correlate alerts into incidents, and provides a unified console for investigation and automated response. Microsoft Defender for Cloud provides posture management and threat protection but does not have the full SIEM/SOAR capabilities. Defender for Endpoint is for endpoints. Defender for Cloud Apps is for cloud applications. Sentinel is the correct choice for this need.
