AWS Certified Cloud Practitioner — Question 200

A company has stopped all of its Amazon EC2 instances but monthly billing charges continue to occur.

What could be causing this? (Choose two.)

Answer options

• A. Amazon Elastic Block Store (Amazon EBS) storage charges
• B. Operating system charges
• C. Hardware charges
• D. Elastic IP charges
• E. Input/output (I/O) charges

Correct answer: A, D

Explanation

The correct answers are A and D because even when EC2 instances are stopped, charges for Amazon EBS storage persist since the data is still stored, and Elastic IP addresses incur costs when allocated but not attached to a running instance. The other options, such as operating system, hardware, and I/O charges, do not apply as they are not incurred when instances are stopped.
