AWS Certified Solutions Architect Professional SAP-C02 Practice Question
A company that uses AWS Organizations with consolidated billing across 20 member accounts needs to forecast the cost impact of launching a new batch-processing workload that will consume about 6,000 vCPU-hours of m7g.4xlarge compute each month in the US East (N. Virginia) Region. Finance also wants to model the purchase of a 1-year, no-upfront Compute Savings Plan for the new usage. The solutions architect must begin with the previous month's actual usage, automatically include all existing Reserved Instances, Savings Plans, and volume-based discounts, add the new usage and commitment, and produce the estimate directly in the AWS Management Console with minimal manual data entry. Which approach will generate the MOST accurate cost estimate in the shortest time?
Generate a custom Savings Plans recommendation report for the additional m7g usage in Cost Explorer and export the results as a CSV file.
Use the public AWS Pricing Calculator website to build a workload estimate by manually entering all existing usage and commitments, then add the new workload and Savings Plan.
Create a forecast budget in AWS Budgets that adds the monthly cost of a 1-year Compute Savings Plan to the current spend baseline.
Use the in-console AWS Pricing Calculator to create a Bill estimate from last month's usage, add the additional EC2 usage and the planned 1-year Compute Savings Plan in the scenario, and run the estimate with the "After discounts and purchase commitments" rate type.
The in-console AWS Pricing Calculator can create a Bill estimate that automatically imports the last month's consolidated usage and all active commitments. Within the Bill scenario the architect can add 6,000 vCPU-hours of the new EC2 instance type and model a 1-year Compute Savings Plan. Running the estimate with the "After discounts and purchase commitments" rate type applies existing volume discounts, Reserved Instances, and Savings Plans, giving an end-to-end view of the new consolidated invoice without affecting production workloads. Cost Explorer recommendations (distractor) only analyze historical spend and cannot model arbitrary future usage or new commitments together. The public (unauthenticated) Pricing Calculator requires manually rebuilding prior usage and does not ingest existing commitments, so results are less accurate and slower to assemble. AWS Budgets forecasts cannot simulate specific Savings Plan purchases or what-if usage changes; they only alert when spend crosses thresholds. Therefore, using the in-console AWS Pricing Calculator Bill estimate is the optimal solution.
