AWS Certified Cloud Practitioner — Question 569

A cloud practitioner is analyzing Amazon EC2 instance performance and usage to provide recommendations for potential cost savings.

Which cloud concept does this analysis demonstrate?

Answer options

• A. Auto scaling
• B. Rightsizing
• C. Load balancing
• D. High availability

Correct answer: B

Explanation

Rightsizing is the process of matching instance sizes and types to your workload performance and capacity requirements at the lowest possible cost. By analyzing Amazon EC2 performance and usage, the cloud practitioner can identify underutilized resources and downsize them to optimize costs. Other concepts like Auto scaling, Load balancing, and High availability focus primarily on scalability, traffic distribution, and fault tolerance rather than cost-optimization analysis.
