AWS Certified Cloud Practitioner (CLF-C02) — Question 195

A customer runs an On-Demand Amazon Linux EC2 instance for 3 hours, 5 minutes, and 6 seconds.

For how much time will the customer be billed?

Answer options

• A. 3 hours, 5 minutes
• B. 3 hours, 5 minutes, and 6 seconds
• C. 3 hours, 6 minutes
• D. 4 hours

Correct answer: B

Explanation

The customer will be billed for the exact duration of 3 hours, 5 minutes, and 6 seconds since AWS bills by the second for On-Demand EC2 instances. Options A, C, and D do not account for the additional 6 seconds, making them incorrect.
