AWS Certified Cloud Practitioner — Question 273

Which of the following is an advantage that the AWS Cloud provides to users?

Answer options

• A. Users eliminate the need to guess about infrastructure capacity requirements.
• B. Users decrease their variable costs by maintaining sole ownership of IT hardware.
• C. Users maintain control of underlying IT infrastructure hardware.
• D. Users maintain control of operating systems for managed services.

Correct answer: A

Explanation

AWS eliminates the need for capacity planning by allowing users to provision resources dynamically on demand, meaning they do not have to guess their infrastructure needs. In the cloud model, AWS manages the physical hardware and the operating systems of managed services, so users do not retain control over those layers. Owning physical hardware would increase capital expenses rather than decreasing variable costs.
