AWS Certified SysOps Administrator – Associate (legacy) — Question 510

A company wants to reduce costs across the entire company after discovering that several AWS accounts were using unauthorized services and incurring extremely high costs.
Which AWS service enables the company to reduce costs by controlling access to AWS services for all AWS accounts?

Answer options

• A. AWS Cost Explorer
• B. AWS Config
• C. AWS Organizations
• D. AWS Budgets

Correct answer: D

Explanation

AWS Budgets allows the company to set custom budgets that track cost or usage and implement budget actions to restrict access or shut down unauthorized resources when thresholds are exceeded. While AWS Cost Explorer is used for visualizing costs and AWS Config tracks resource changes, they do not actively control access based on budget limits. AWS Organizations can restrict service access via SCPs, but AWS Budgets is the primary tool for directly linking cost thresholds to access control actions to prevent cost overruns.
