ANS-C01 Network Security, Compliance and Governance Practice Question

Answer choices
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
✓
Amazon CloudWatch
AWS Shield Advanced integrates with Amazon CloudWatch to emit DDoS detection metrics. You can create a CloudWatch alarm based on these metrics (e.g., DDoSDetected) to send notifications via SNS. Option A (AWS Config) is for resource configuration auditing, not DDoS notifications. Option C (VPC Flow Logs) captures network traffic metadata but does not provide Shield-specific alerts. Option D (Amazon GuardDuty) is a threat detection service, but it does not directly provide Shield Advanced event notifications.
