AWS Certified Solutions Architect Professional SAP-C02 Practice Question

A large enterprise uses AWS Organizations to manage dozens of member accounts. The finance team has reported a significant, unexpected increase in AWS costs. The existing approach of using the basic views in AWS Cost Explorer is not providing the necessary granular insights to identify the specific services, API operations, or tagged resources responsible for the cost overrun. The company needs a long-term, scalable solution to perform detailed cost and usage analysis and accurately allocate costs to various business units based on resource tags. Which approach is the MOST cost-effective and scalable for achieving this objective?

  • Enable hourly and resource-level granularity in AWS Cost Explorer for all member accounts. Activate all necessary cost allocation tags in the billing console. Use the advanced filtering and grouping features within Cost Explorer to manually investigate the cost spikes.

  • Enable AWS CloudTrail across the organization, storing logs in a central S3 bucket. Analyze the CloudTrail logs using Amazon S3 Select to identify high-frequency API calls that correlate with cost increases and attribute them to the responsible teams.

  • Create a consolidated AWS Budget for the entire organization with an alert that notifies the finance team via an SNS topic. Configure multiple, service-specific budgets for high-cost services to narrow down the source of overages.

  • Configure an AWS Cost and Usage Report (CUR) to be delivered to an Amazon S3 bucket. Use Amazon Athena to query the CUR data directly in S3. Build detailed, interactive dashboards in Amazon QuickSight using the Athena query results to visualize cost drivers and allocate expenses based on tags.
