Which type of AWS storage is ephemeral and is deleted when an Amazon EC2 instance is stopped or terminated?
Amazon Elastic Block Store (Amazon EBS)
Amazon EC2 instance store
Amazon Elastic File System (Amazon EFS)
Amazon S3
Explanations:
Amazon EBS volumes persist independently of the EC2 instance lifecycle.
Amazon EC2 instance store provides ephemeral storage that is lost when the instance is stopped or terminated.
Amazon EFS is a persistent, scalable file storage service that remains available regardless of EC2 instance state.
Amazon S3 is a durable, object storage service that retains data even when instances are stopped or terminated.
I organize that the answer is:
Amazon EC2 instance store
