A security operations team investigates a multi-stage attack that began with a phishing email, then moved to credential compromise, and finally to lateral movement on endpoints. They need a single pane of glass to view the entire attack story, including the initial email, the compromised user's sign-in activities, and processes on affected devices. Which Microsoft security solution provides this unified investigation experience?

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 Sentinel

Sentinel is a cloud-native SIEM that can ingest logs from various sources, but it does not provide native, pre-built correlation across all M365 workloads like Microsoft 365 Defender does.

B

Distractor review

Microsoft Defender for Cloud

Defender for Cloud protects cloud workloads but does not unify email and identity threat data.

C

Best answer

Microsoft 365 Defender

Microsoft 365 Defender unifies alerts and incidents from Microsoft Defender for Endpoint, Defender for Office 365, Defender for Identity, and Defender for Cloud Apps into a single view.

D

Distractor review

Microsoft Defender for Identity

Defender for Identity focuses on on-premises Active Directory threats; it does not provide the full cross-domain investigation.

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 365 Defender — Microsoft 365 Defender (the unified portal) correlates signals across email, endpoint, identity, and cloud apps to provide a consolidated incident view. Microsoft Sentinel is a SIEM that aggregates logs from multiple sources but does not natively provide the same deep integration with Microsoft 365 services as Microsoft 365 Defender.
