Correct Answer: A

Explanation: An Amazon EBS-optimized instance uses an optimized configuration stack and provides additional, dedicated capacity for the Amazon EBS I/O. This optimization provides the best performance for the user’s Amazon EBS volumes by minimizing contention between the Amazon EBS I/O and other traffic from the user’s instance.
