Which AWS service or traffic filter will meet these requirements with the MOST features for DDoS protection?

Explanations:

AWS Shield Advanced provides comprehensive DDoS protection, including near real-time visibility into attacks, detailed reporting, and access to DDoS cost protection. It also offers integration with AWS services like CloudFront and Route 53, and has advanced features such as anomaly detection and response features.

AWS Shield is a managed DDoS protection service, but it only provides basic DDoS protection without the advanced features like real-time visibility and detailed reporting that are available in Shield Advanced. It is primarily designed for standard DDoS protection.

Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior but does not specifically provide DDoS protection or near real-time visibility into DDoS attacks. It focuses more on general security threat detection rather than DDoS mitigation.

Network ACLs (Access Control Lists) provide basic network security by controlling inbound and outbound traffic at the subnet level, but they do not offer specialized DDoS protection features or real-time monitoring capabilities. They are not designed to protect against DDoS attacks specifically.
