SAP-C02Domain 3: Continuous Improvement for Existing SolutionsArchitecture OptimizationmediumSingle choice
Across 300 accounts, which service analyzes CloudWatch utilization history and recommends right-sized EC2/EBS/Lambda configurations at scale?
A.AWS Trusted Advisor
Advisor flags underutilized instances — Compute Optimizer is the deeper ML-based rightsizer.
B.AWS Compute Optimizer
ML-based rightsizing recommendations. Correct.
C.AWS Cost Explorer
Explorer shows cost history — not configuration recommendations.
D.Amazon Inspector
Inspector scans vulnerabilities — unrelated to sizing.
Why this answer
Compute Optimizer uses ML over utilization metrics to recommend right-sizing for EC2, EBS, Lambda, ECS, and ASGs — including projected performance risk. Cost Explorer reports spend; Trusted Advisor gives broad best-practice checks.
