AWS Certified Cloud Practitioner — Question 672

An ecommerce company plans to move its data center workload to the AWS Cloud to support highly dynamic usage patterns.

Which benefits make the AWS Cloud cost-effective for the migration of this type of workload? (Choose two.)

Answer options

• A. Reliability
• B. Security
• C. Elasticity
• D. Pay-as-you-go resource pricing
• E. High availability

Correct answer: C, D

Explanation

Elasticity allows the company to dynamically scale resources up or down to match real-time demand, preventing the need to pay for idle capacity. When paired with a pay-as-you-go pricing model, the business only pays for the exact infrastructure consumed, optimizing costs for fluctuating workloads. While reliability, security, and high availability are critical AWS benefits, they do not directly drive cost-effectiveness for dynamic usage patterns.
