Question 200
In a production architecture assessment, the decisive constraint is: A production VPC needs inline stateful filtering of suspicious east-west and egress traffic. What is the most appropriate design under these constraints?
Explanation
Correct Answer
Route relevant paths through AWS Network Firewall endpoints and rule groups. The choice follows from the service boundary and operational constraint stated in the scenario.
Incorrect Answers
Evaluate AWS Shield Advanced and appropriate protected resources would address a different requirement: A public service must withstand large volumetric DDoS events and needs specialized incident support. Shield Advanced adds advanced DDoS capabilities and response support beyond standard protections.
This alternative, Use GuardDuty threat findings and an approved isolation response procedure, is appropriate when A container workload shows suspicious outbound calls to a known command-and-control address. GuardDuty detects suspicious account and network behavior for investigation.
For the separate situation A public API experiences HTTP request flooding and needs customizable managed request-rate blocking, Attach AWS WAF rate-based rules to the protected API or CloudFront distribution could be useful. AWS WAF filters HTTP-layer requests using configurable web ACL rules.
