AWS Certified Solutions Architect Professional SAP-C02 Practice Question
Your company operates 30 AWS accounts that are organized with AWS Organizations. Finance wants an interactive Amazon QuickSight dashboard that shows charge-back information by linked account, cost category, and cost-allocation tag. The reporting solution must do the following:
Include resource-ID-level cost details.
Refresh automatically at least once every 24 hours.
Retain all historical cost data for multi-year trend analysis.
Minimize operational overhead and avoid third-party tools.
Which approach will meet these requirements?
Enable an AWS Cost and Usage Report with resource-ID and hourly granularity in the management account. Deliver the report to an Amazon S3 bucket and turn on the Cost and usage dashboard powered by QuickSight to visualize the data.
Export cost-optimization check results from AWS Trusted Advisor for every account to Amazon S3 each day and use AWS Glue and QuickSight to create cost dashboards from the exported reports.
Create individual AWS Budgets for each linked account, have the budgets send daily Amazon SNS notifications, store the notifications in Amazon S3 through an AWS Lambda subscriber, and build QuickSight visuals from the stored messages.
Enable hourly granularity in AWS Cost Explorer and schedule a daily AWS Lambda function to call the Cost Explorer API, store the CSV output in Amazon S3, and query it with Amazon Athena for QuickSight dashboards.
An AWS Cost and Usage Report (CUR) satisfies every requirement. CUR delivers the most granular cost and usage data-including resource IDs, tags, and cost categories-directly to an Amazon S3 bucket and updates it up to three times per day. The CUR data can be visualized without custom ETL by enabling the built-in Cost and usage dashboard powered by QuickSight, and the files stay in S3 for as long as the company's retention policy allows.
Cost Explorer exports do not meet the retention or granularity needs: Cost Explorer keeps only about 13 months of history and its resource-level API is limited to the last 14 days. AWS Budgets generates threshold notifications rather than full cost datasets and updates only a few times per day. AWS Trusted Advisor provides optimization recommendations, not detailed, tag-based cost records. Therefore, enabling CUR with QuickSight integration is the only option that fulfills all the stated requirements.
