The Development Team of a gaming application firm needs to test new gaming apps on various EC2 instances with multiple OS platforms. To avoid delay in the setup of these EC2 instances, the IT head has decided to launch some EC2 instances with all required application components & hibernate these instances. The Accounts Team is concerned about the cost incurred for these hibernated EC2 instances. Which of the following is the correct statement for charges incurred for an EC2 instance in a hibernation state?

Answer options:

A.EBS storage charges & Elastic IP Address charges attached to Instance.
B.Instance charges per second for duration of hibernation & S3 storage charges for data copied from Instance to S3 bucket.
C.S3 Storage charges & Elastic IP Address charges attached to Instance.
D.Instance charges per second for duration of hibernation & EBS storage charges.

Correct Answer – A
When an EC2 instance is hibernated, the following are charged.
1) EBS storage charges for in-memory data saved in EBS volumes.
2) Elastic IP address charges which are associated with an instance.
Option B is incorrect as When the EC2 instance is hibernated, in-memory data is stored in EBS volumes & not the S3 bucket. So, no charges are incurred for the S3 bucket. Also, in a hibernated state there are no charges for instance.
Option C is incorrect as When the EC2 instance is hibernated, in-memory data is stored in EBS volumes & not the S3 bucket. So, no charges are incurred for S3 bucket.
Option D is incorrect as in a hibernated state there are no charges for instance.
