MS-102 Automatic attack disruption Practice Question
Your organization uses Microsoft Defender XDR. You need to configure automatic attack disruption for SaaS applications. Which Microsoft 365 security solution provides this capability?
⚠ Common exam trap
Candidates often confuse Microsoft Defender for Cloud Apps with other Defender products. Remember that automatic attack disruption for SaaS is unique to Defender for Cloud Apps.

Why each option matters
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 Cloud Apps
Microsoft Defender for Cloud Apps (Option B) provides automatic attack disruption for SaaS applications by using risk indicators and automation to stop attacks in real time. Option A (Microsoft Defender for Identity) focuses on on-premises Active Directory and identity threats, not SaaS apps. Option C (Microsoft Defender for Office 365) protects email and collaboration tools. Option D (Microsoft Defender for Endpoint) secures endpoints like desktops and servers. Therefore, only option B delivers the required capability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft Defender for Identity
Why it's wrong here
Defender for Identity monitors on-premises Active Directory domain controllers for identity-based attacks; it cannot disrupt SaaS app sessions. It is tempting because identity signals feed attack disruption, but the SaaS-specific capability belongs to Defender for Cloud Apps, which correlates app sessions and suspends compromised accounts.
- ✓
Microsoft Defender for Cloud Apps
Why this is correct
Microsoft Defender for Cloud Apps delivers automatic attack disruption for SaaS apps by correlating signals from Microsoft Entra ID and Defender XDR to identify compromised sessions or malicious OAuth apps, then containing the threat mid-attack. This satisfies the stem's requirement for a Microsoft 365 security solution providing SaaS-specific disruption.
- ✗
Microsoft Defender for Office 365
Why it's wrong here
Defender for Office 365 protects email and collaboration workloads; it does not deliver automatic attack disruption for SaaS apps. It is tempting because it is part of Microsoft Defender XDR, and it is correct for phishing, malware and collaboration threat protection, but SaaS disruption requires Defender for Cloud Apps.
- ✗
Microsoft Defender for Endpoint
Why it's wrong here
Defender for Endpoint isolates and remediates devices, not SaaS application sessions; its automated response targets endpoints. It is tempting because attack disruption uses endpoint signals, but containing a compromised SaaS user requires Defender for Cloud Apps, which enforces session and app-level controls.
