Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Close the vulnerability that was exploited.
Option D is correct because closing the vulnerability prevents recurrence. Root cause analysis is part of post-incident, customer notification is legal/compliance, and system restoration is part of recovery.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
