AWS Certified Cloud Practitioner (CLF-C02) — Question 247

In which ways does the AWS Cloud offer lower total cost of ownership (TCO) of computing resources than on-premises data centers? (Choose two.)

Answer options

• A. AWS replaces upfront capital expenditures with pay-as-you-go costs.
• B. AWS is designed for high availability, which eliminates user downtime.
• C. AWS eliminates the need for on-premises IT staff.
• D. AWS uses economies of scale to continually reduce prices.
• E. AWS offers a single pricing model for Amazon EC2 instances.

Correct answer: A, D

Explanation

The correct answers are A and D because AWS allows users to avoid large upfront investments by using a pay-as-you-go model, which lowers TCO. Additionally, AWS can reduce prices over time through economies of scale, benefiting all users. Options B, C, and E do not directly relate to TCO in the same way, as they focus on availability, staffing, and pricing structure rather than overall cost savings.
