AWS Certified Cloud Practitioner — Question 944

Which of the following is a benefit of moving from an on-premises data center to the AWS Cloud?

Answer options

• A. Compute instances can be launched and terminated as needed to optimize costs.
• B. Compute costs can be viewed in the AWS Billing and Cost Management console.
• C. Users retain full administrative access to their compute instances.
• D. Users can optimize costs by permanently running enough instances at peak load.

Correct answer: A

Explanation

Migrating to the AWS Cloud enables elasticity, allowing users to scale compute resources up or down dynamically to match demand and reduce unnecessary spending. While AWS Billing and Cost Management tools and administrative access are available, they do not represent the core cost-efficiency benefits of cloud elasticity. Running instances continuously at peak load defeats the purpose of cloud optimization and leads to higher, unnecessary costs.
