Question 580
What outcome would most directly confirm the intended AWS benefit? A team runs a large general-purpose compute instance even though monitoring shows minimal CPU and memory use.
Explanation
Correct Answer
Resource cost falls while application service requirements remain met. The case involves: A team runs a large general-purpose compute instance even though monitoring shows minimal CPU and memory use. The central AWS principle is that rightsizing means choosing resources aligned to actual workload needs. What matters is: Look for consistently low utilization and excessive instance capacity. Recommended direction: Select a smaller suitable resource after evaluating demand and headroom. Expected indication of success: Resource cost falls while application service requirements remain met. Caveat: Averages can hide short peaks, so rightsize using representative metrics.
Incorrect Answers
Cloud savings require active cost governance rather than assuming migration itself guarantees lower spending. That addresses a different mechanism; this question turns on Resource cost falls while application service requirements remain met.
Automation reduces repetitive provisioning effort and can lower operational overhead. In the present case the governing issue is Rightsizing means choosing resources aligned to actual workload needs, which this does not resolve.
Cloud variable-cost economics support reducing capacity during predictable low-use periods. That observation may hold without resolving the relevant issue: Resource cost falls while application service requirements remain met.
