AWS Certified Cloud Practitioner — Question 332

Which of the following is a cost efficiency principle related to the AWS Cloud?

Answer options

• A. Right size services based on capacity requirements
• B. Use the Billing Dashboard to access information about monthly bills
• C. Use AWS Organizations to combine the expenses of multiple accounts into a single bill
• D. Tag all AWS resources

Correct answer: A

Explanation

Right-sizing services ensures that you only pay for the resources you actually need, making it a fundamental design principle of AWS cost efficiency. While tools like the Billing Dashboard, AWS Organizations consolidated billing, and resource tagging help manage, track, and organize costs, they are administrative mechanisms rather than direct cost-efficiency principles.
