You are working as an AWS Architect for a software company. You are working on a new project which involves an application deployed on twenty C5 EC2 On-demand Instances with Elastic IP attached to each instance. During peak hours, when you are initiating new instances, a considerable delay is observed. You perform a pilot test for the option of initiating these Instances and hibernating so that during peak hours, these instances could be quickly launched.
It works fine during the pilot phase. You are recommending this option to be implemented in production. The management team is concerned about the pricing of many EC2 instances in the Hibernate state. What is considered to calculate the pricing for an EC2 instance in the Hibernate state?

Answer options:

A.Elastic IP address and EBS volumes attached to EC2 Instance
B.Total Compute capacity per hour, Elastic IP address and EBS volumes attached to EC2 Instance
C.Total Compute capacity per hour and EBS volumes attached to EC2 Instance
D.Total Compute capacity per hour & Elastic IP address attached to EC2 Instance

Correct Answer –A
When an EC2 instance is in the Hibernate state, you pay only for the EBS volumes and Elastic IP Addresses attached to it.
Options B, C, and D are incorrect because when an EC2 instance is in a hibernate state, compute capacity charges are not applicable. The charges are only applicable for the EBS volumes and Elastic IP Addresses attached to it.
