Which of these is an example of "rightsizing" in AWS cost optimization?
AProvisioning EC2 instances in every AWS Region for resilience
BBuying the largest instance type available for every workload
CMatching an EC2 instance type to actual CPU and memory needs of the workload
DUsing only Reserved Instances regardless of workload pattern
Answer & Solution
Correct answer: C. Matching an EC2 instance type to actual CPU and memory needs of the workload
Rightsizing means selecting an instance family and size that matches a workload's actual utilization profile rather than over- or under-provisioning. The other options describe over-provisioning patterns.
