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
✓
AWS Shield Advanced subscription
Options A, D, and E are correct. AWS Shield Advanced requires an active subscription (A) to enable automatic application layer DDoS mitigation. It integrates with AWS WAF, so a web ACL (E) must be associated with the ALB, and a rate-based rule (D) is needed to trigger automatic mitigation. Option B (CloudFront) is not required because Shield Advanced can directly protect ALBs without a CDN. Option C (Route53) is also not required for this specific feature.
