Amazon GuardDuty
GuardDuty is a service that analyzes logs to detect suspicious activity and threats.
Its role is threat detection, not dedicated DDoS attack mitigation, so this is incorrect.
Which AWS service is specifically designed to protect applications on AWS from DDoS attacks that flood the service with large volumes of requests and cause it to stop responding?
A question asking to identify the service dedicated to DDoS attack protection.
Amazon GuardDuty
GuardDuty is a service that analyzes logs to detect suspicious activity and threats.
Its role is threat detection, not dedicated DDoS attack mitigation, so this is incorrect.
AWS Shield
This is correct. AWS Shield is a service specifically designed for protection against DDoS attacks. Shield Standard is automatically applied to all customers at no extra cost, and Shield Advanced provides more advanced protection and response support as a paid offering. It mitigates service disruption caused by large volumes of requests.
AWS KMS
KMS is a service for managing encryption keys.
Its role is data encryption, which is unrelated to DDoS mitigation, so this is incorrect.
Amazon Inspector
Inspector is a service that automatically scans EC2 instances and container images for vulnerabilities.
Vulnerability assessment is its role, and it is not dedicated to DDoS mitigation, so this is incorrect.
'DDoS' points to AWS Shield (Standard = automatic and free / Advanced = paid). Differentiate: web-application-layer attacks (SQLi/XSS) = WAF; threat detection = GuardDuty; vulnerability scanning = Inspector.
