AWS Certified Cloud Practitioner

Explanation

Correct Answers: B and C

B. Having the pay as you go model, so you don't need to worry if you are burning costs for non-running resources.

• This is correct because AWS's pay-as-you-go pricing model means you only pay for the resources you actually use. If you stop or terminate resources, you don't continue paying for them, eliminating the worry about costs for non-running resources.

C. No Upfront costs

• This is correct because AWS operates on a pay-as-you-go model with no upfront costs or long-term commitments required for most services. You only pay for what you use, which eliminates the headache of large initial investments.

Why the other options are incorrect:

A. Having complete control over the physical infrastructure, so you don't need to worry about what AWS is doing.

• This is incorrect because while AWS manages the physical infrastructure, you still need to understand and monitor AWS's shared responsibility model. You don't have complete control over the physical infrastructure, and you should be aware of AWS's operational practices.

D. Having no need to worry about security

• This is incorrect because security is a shared responsibility in AWS. While AWS manages security OF the cloud (infrastructure), customers are responsible for security IN the cloud (their applications, data, and configurations). You absolutely need to worry about security in your AWS environment.

These benefits (B and C) are key advantages of the AWS cloud computing model that eliminate traditional IT headaches associated with on-premises infrastructure.
