Question #755
A company manages hundreds of AWS accounts using an organization in AWS Organizations with all features enabled. The finance team requires a monthly budget for AWS costs and must receive an email notification if the organization's costs exceed 90% of the allocated budget. A solutions architect must design a solution to monitor costs and trigger alerts.
Which solution meets these requirements?
In the organization's management account, create a monthly AWS Budget with an alert threshold set to 90%. Use Amazon SNS to notify the finance team when the threshold is exceeded.
Register the organization with AWS Control Tower. Configure a cost control guardrail with a 90% limit. Use Amazon SNS to send notifications to the finance team when the guardrail is breached.
Enable the organizational view feature for AWS Trusted Advisor in the management account. Generate a cost optimization report with a 90% alert threshold and configure email notifications for the finance team.
Configure all member accounts to export daily AWS Cost and Usage Reports to a centralized Amazon S3 bucket. Use AWS Glue to create a table, schedule daily Athena queries to aggregate costs, and trigger a CloudWatch alarm if costs exceed 90% of the budget. Use Amazon SNS for notifications.
Explanation
Answer A is correct because AWS Budgets natively supports organization-wide cost tracking when configured in the management account. It can aggregate costs across all member accounts and trigger alerts via Amazon SNS when the threshold (90%) is reached. Other options are incorrect: B (Control Tower guardrails enforce policies, not budgets), C (Trusted Advisor provides recommendations, not budget alerts), and D (overly complex custom solution vs. built-in AWS Budgets functionality). Key points: Use AWS Budgets for organization-wide budget monitoring and SNS for alerts.
Answer
The correct answer is: A
