Why each option

To optimize costs, the CSA should identify overprovisioned resources and reduce their instance size to align with actual utilization.

AChange the MW01, MW02, and MW03 servers to the MEDIUM instance type.

Changing MW servers to MEDIUM would increase costs if they are currently smaller or keep costs the same if they are already medium and properly utilized, not necessarily reducing overall costs optimally as intended by the question.

BChange the PROXY01 server to the MEDIUM instance type.
CChange the DB01 server to the LARGE instance type.
DChange the WEB01 server to the SMALL instance type.Correct

Changing the WEB01 server to a SMALL instance type suggests that WEB01 is currently overprovisioned (e.g., a MEDIUM or LARGE instance) and consistently operates with low resource utilization. Downsizing to a smaller instance type directly reduces infrastructure costs while maintaining adequate performance for the application's web tier, achieving optimal sizing.
