Answer: Utilizing a pay-as-you-go pricing model, Eliminating the need to predict required capacity

The correct answers are B and D. AWS Cloud offers a pay-as-you-go model (B), which means you only pay for the resources you use, without upfront costs or long-term commitments. This provides cost efficiency and flexibility. Additionally, AWS handles the infrastructure, allowing you to focus on your applications rather than capacity planning (D). You no longer need to guess or manage the physical infrastructure's capacity requirements. Options A and C are incorrect because AWS does not take over all security responsibilities; they follow a shared responsibility model. Customers are responsible for security 'in' the cloud, while AWS is responsible for security 'of' the cloud. Option C is also incorrect because AWS is a cloud service provider, and customers do not have control over the physical infrastructure. Option E is incorrect because managing user access controls is still the customer's responsibility, even when using AWS services.
