Answer options

• A. Rightsizing

Correct answer: A

Explanation

AWS Cost Explorer helps users analyze their spending and usage patterns to identify over-provisioned or idle resources, which directly supports the cloud concept of rightsizing to optimize costs. In contrast, reliability and resilience focus on a system's dependability and recovery capabilities, while modernization refers to upgrading legacy architectures to cloud-native solutions.
