AWS Certified Cloud Practitioner — Question 727

Which factors affect costs in the AWS Cloud? (Choose two.)

Answer options

• A. The number of unused AWS Lambda functions
• B. The number of configured Amazon S3 buckets
• C. Inbound data transfers without acceleration
• D. Outbound data transfers without acceleration
• E. Compute resources that are currently in use

Correct answer: D, E

Explanation

In the AWS Cloud, outbound data transfer (data leaving AWS) and active compute resources (such as running EC2 instances) are primary cost drivers. Conversely, inbound data transfer is typically free, and AWS does not charge for the mere existence of empty Amazon S3 buckets or inactive AWS Lambda functions.
