Quick Answer
The answer is the investigation package, because it is the Microsoft 365 Defender feature specifically designed to collect and present all evidence needed to identify compromised accounts after a credential phishing attack. When a user clicks a malicious link and enters credentials on a phishing page, the investigation package aggregates related emails, URL clicks, sign-in logs, and user actions into a single, downloadable ZIP file, allowing you to trace exactly which accounts were affected. On the MS-102 exam, this question tests your ability to distinguish between features that handle automated remediation (like automated investigation and response), device-level analysis, or file-level analysis versus the comprehensive evidence collection required for post-phishing account compromise. A common trap is confusing the investigation package with the device investigation feature, but remember: phishing targets user credentials, not devices. Memory tip: think of the investigation package as the “evidence locker” for user-level phishing incidents—it packages up everything you need to see who logged in after the phish.
