Customer Responsibility

The correct answer is B. Create EBS snapshots.

Amazon Elastic Block Store (EBS) is a service that provides persistent block-level storage volumes for use with Amazon EC2 instances. EBS volumes are automatically replicated within an Availability Zone (AZ) to protect against component failure. However, it is the responsibility of the customer to ensure the availability and backup of their data stored on EBS volumes.

Here is an explanation of each answer choice:

A. Delete the data and create a new EBS volume: This is not a recommended way to ensure availability and backup of EBS volumes. Deleting the data would result in a loss of data, and creating a new EBS volume would require the customer to restore the data from a backup.

B. Create EBS snapshots: This is the correct answer. EBS snapshots are point-in-time copies of EBS volumes that can be used to back up data, migrate data to a new EBS volume, or create new EBS volumes. Snapshots are stored in Amazon S3, and are incremental backups that only store the data that has changed since the last snapshot.

C. Attach new volumes to EC2 Instances: While attaching new volumes to EC2 instances is a necessary step to access the data on the volumes, it is not a way to ensure availability and backup of the data.

D. Create copies of EBS Volumes: Creating copies of EBS volumes is similar to creating snapshots, but it creates a duplicate of the entire volume instead of an incremental backup. This can be useful for creating backups, but it is not the recommended way to ensure availability and backup of EBS volumes.

In summary, the customer is responsible for ensuring
