The answer is to run a KQL query on EmailEvents and check the email’s status in Microsoft Defender for Office 365 Threat Explorer. These two actions are correct because the KQL query on EmailEvents allows the analyst to trace the phishing email’s delivery and identify the affected user, while Defender for Office 365 Threat Explorer provides the real-time threat verdict and any post-delivery actions taken, such as zero-hour auto purge. On the SC-200 exam, this scenario tests your ability to triage phishing incidents without jumping to remediation—common traps include prematurely resetting the user’s password or deleting the email before confirming compromise, which can destroy forensic evidence. Remember that investigation always precedes containment; the KQL query gives you the “who and what,” and Threat Explorer gives you the “status and risk.” A useful memory tip is “Query first, Explorer second—never delete or reset until the threat is fully assessed.”
