An organization uses Microsoft 365 Defender. The security team receives an alert about a potential malware outbreak on multiple endpoints, and they need an integrated view that correlates signals from various Microsoft security solutions. Which Microsoft 365 Defender portal component provides this unified view?
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
Defender for Cloud protects cloud workloads (VMs, SQL, etc.) but does not correlate endpoint and email signals.
B
Best answer
Microsoft 365 Defender portal (security.microsoft.com)
This portal provides a unified view of threats across endpoints, email, identities, and apps, with integrated incident response.
C
Distractor review
Azure Sentinel
Azure Sentinel is a separate SIEM that can ingest data but does not provide the native integration of Microsoft 365 Defender.
D
Distractor review
Microsoft Defender for Identity
Defender for Identity focuses on Active Directory signals; it does not unify endpoint or email threat data.
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 portal (security.microsoft.com) — The Microsoft 365 Defender portal (security.microsoft.com) is the central hub that aggregates signals from Microsoft Defender for Endpoint, Defender for Office 365, Defender for Identity, and Microsoft Cloud App Security. It provides incident management, automated investigation, and a unified queue of alerts. Microsoft Defender for Cloud (Option A) focuses on cloud workload protection. Azure Sentinel (Option C) is a cloud-native SIEM that can ingest data but is separate from the integrated Microsoft 365 Defender experience. Microsoft Defender for Identity (Option D) only covers identity-based threats. Therefore, the correct answer is the Microsoft 365 Defender portal.
