Study SAP-C02 Cost Optimization Opportunities: key concepts, common traps, and exam decision cues.
Cost-optimization questions for existing solutions ask whether you can find and remove waste without damaging the architecture. SAP-C02 wants you to improve cost visibility, eliminate underused resources, and choose better AWS pricing models based on actual usage.
| Need | Strongest first fit | Why |
|---|---|---|
| unclear detailed spend drivers | CUR analysis | deepest billing detail |
| untracked spend spikes | AWS Budgets and alerts | threshold-based warning |
| unknown idle or underused resources | usage reports and optimization tools | evidence-based cleanup |
| poor cost ownership | tagging and allocation improvement | maps spend to teams and services |
| stable usage paying on-demand rates | Savings Plans or Reserved Instances review | better pricing alignment |
| Trap | Better rule |
|---|---|
| cutting resources before understanding dependency impact | optimize with architecture awareness |
| chasing price model changes without visibility | reporting and ownership should come first |
| ignoring unused resources because they are “small” | small repeated waste compounds fast at scale |
| treating tagging as optional | cost accountability depends on it |
Cost-improvement questions usually reward visibility before cuts. If no one can explain spend ownership, fix tagging and allocation first. If the fleet has stable baseline usage, evaluate commitments. If you need detailed billing evidence, use CUR. SAP-C02 often treats cost improvement as a measurement and governance problem before it becomes a purchasing problem.
