Ans: B https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Hibernate.html 1. Hibernate: To preserve contents of the instance's memory whenever the instance is unavailable. https://aws.amazon.com/blogs/aws/new-hibernate-your-ec2-instances/ 2. Cost consideration: While the instance is in hibernation, you pay only for the EBS volumes and Elastic IP Addresses attached to it; there are no other hourly charges (just like any other stopped instance).

I'm confused, why the hybernation is the MOST SECURE ? For example why Hiberantion is most secure than terminate the instance and start it using an AMI?

The hibernation process stores the in-memory state of the instance, along with its private and elastic IP addresses, allowing it to pick up exactly where it left off.
