AWS Certified Cloud Practitioner (CLF-C02) — Question 389

A company is in the process of finding correct Amazon EC2 instance types and sizes to meet its performance and capacity requirements. The company wants to find the lowest possible cost.

Which option accurately characterizes the company's actions?

Answer options

• A. Auto Scaling
• B. Storage tiering
• C. Rightsizing
• D. Instance scheduling

Correct answer: C

Explanation

Rightsizing is the process of matching instance types and sizes to your workload performance and capacity requirements at the lowest possible cost. While Auto Scaling and instance scheduling help manage costs by adjusting the number of active instances, they do not involve selecting the optimal baseline instance size. Storage tiering is a cost-optimization technique specifically for data storage rather than compute instances.
