The team will stop development EC2 instances outside working hours and review an oversized instance.
It wants to identify two actions that address these different sources of cost.
Choose TWO appropriate actions.
Rightsizing addresses capacity that exceeds requirements, while automation addresses resources that run longer than needed; both can reduce cost without indiscriminate deletion.
Detailed explanation
Scheduled automation reduces runtime outside the required schedule and avoids relying on manual memory.

Rightsizing targets oversized or otherwise unsuitable capacity using measurements and workload requirements.

Maximum sizing increases unnecessary capacity and conflicts with cost optimization.

Unplanned deletion can break workloads; cost optimization requires measurement and controlled changes.

Foundation review
Combine levers
Size, schedule, and commitment duration are separate cost levers that can be improved together.
Controlled change
Cost reduction should preserve required service behavior rather than remove resources indiscriminately.
