The answer is Microsoft Defender for Endpoint and Microsoft Defender for Office 365. These two components are included within the Microsoft 365 Defender integrated solution because the platform is designed to unify threat detection and response across an organization’s entire digital estate, specifically endpoints and collaboration workloads. Microsoft Defender for Endpoint provides advanced endpoint detection and response (EDR) for devices, while Microsoft Defender for Office 365 safeguards email, phishing, and collaboration tools. On the SC-900 exam, this question tests your understanding of the core pillars of Microsoft 365 Defender, often appearing as a select-all-that-apply item where a common trap is including Microsoft Defender for Identity or Cloud Apps as core components—though those are part of the broader suite, the question specifically asks for the two that form the integrated solution’s foundation. A helpful memory tip is to think of the phrase “Devices and Inboxes,” linking Endpoint to devices and Office 365 to inboxes, which covers the two primary attack surfaces unified in the Defender portal.

A company has deployed Microsoft 365 Defender to unify threat detection and response. Which two components are included within the Microsoft 365 Defender integrated solution? (Select all that apply.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Defender for Endpoint
Microsoft 365 Defender is an integrated threat protection suite that unifies detection and response across an organization's Microsoft 365 environment. It includes Microsoft Defender for Endpoint, which provides endpoint detection and response (EDR) capabilities for devices, and Microsoft Defender for Office 365, which protects against email, phishing, and collaboration threats. These two components work together within the Microsoft 365 Defender portal to correlate alerts and automate response across endpoints and Office 365 workloads.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Microsoft Defender for Cloud
Why it's wrong here
Defender for Cloud is a separate service for cloud infrastructure security and is not part of Microsoft 365 Defender.
✓
Microsoft Defender for Office 365
Why this is correct
Defender for Office 365 is included in Microsoft 365 Defender, protecting email and collaboration tools.
Related concept
Read the scenario before looking for a memorised answer.
✗
Microsoft Sentinel
Why it's wrong here
Sentinel is a cloud-native SIEM, not a component of Microsoft 365 Defender. It can integrate with Microsoft 365 Defender but is separate.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Microsoft Defender for Cloud (a cloud security solution) with Microsoft Defender for Cloud Apps (a CASB component of Microsoft 365 Defender), leading them to incorrectly select Defender for Cloud as part of the integrated solution.
Detailed technical explanation
How to think about this question
Microsoft 365 Defender uses a unified correlation engine that ingests signals from Defender for Endpoint, Defender for Office 365, Defender for Identity, and Defender for Cloud Apps to create a single incident timeline. For example, a phishing email detected by Defender for Office 365 can trigger automatic investigation and remediation on endpoints via Defender for Endpoint, without requiring manual correlation. This cross-workload integration is achieved through the Microsoft 365 Defender API and the common alert schema, enabling automated playbooks in Microsoft Sentinel if connected.

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.
