Question 780
A professional architect is reviewing two independent workstreams. Requirement A: Two Regions are deployed but customer requests stay routed to the failed primary endpoint indefinitely. Requirement B: A shared S3 estate has ballooning noncurrent versions, incomplete multipart uploads and forgotten small objects. Select TWO actions, one for each independently scoped requirement.
Explanation
Correct Answers
This action meets the independently stated requirement B: A shared S3 estate has ballooning noncurrent versions, incomplete multipart uploads and forgotten small objects. S3 analytics and lifecycle rules target recoverable storage waste when retention is respected. A direct acceptance check is: Identified buckets show smaller unnecessary version and multipart storage after retention-safe cleanup.
This action meets the independently stated requirement A: Two Regions are deployed but customer requests stay routed to the failed primary endpoint indefinitely. DNS failover needs a health-signal and routing policy that actually switches answers. A direct acceptance check is: After a simulated endpoint failure, new DNS queries return the secondary healthy Region.
Incorrect Answers
This action targets a different technical need: Service owners cannot separate API traffic incidents from infrastructure incidents across ten microservices. It does not replace either required solution in A or B. Meaningful dashboards align telemetry with system service boundaries and indicators; verify the two stated requirements independently rather than accepting an unrelated change.
This action targets a different technical need: Operations retains detached EBS volumes after instance termination and pays for unused storage for months. It does not replace either required solution in A or B. EBS storage billing continues for allocated volumes until they are deleted or otherwise changed; verify the two stated requirements independently rather than accepting an unrelated change.
This action targets a different technical need: An EKS service experiences 503 errors during rolling updates because pods accept traffic before dependencies initialize. It does not replace either required solution in A or B. Readiness and graceful termination controls reduce errors during normal rolling changes; verify the two stated requirements independently rather than accepting an unrelated change.
