Which of the following describes EBS encryption?

EBS encryption is specifically designed to provide data-at-rest encryption for Amazon Elastic Block Store (EBS) volumes. This feature ensures that data stored on the EBS volumes is encrypted, providing a layer of security by protecting sensitive information from unauthorized access. The encryption is handled transparently and uses AWS Key Management Service (KMS) for managing the encryption keys, which simplifies the process for users by integrating encryption seamlessly into their storage management workflow.

This encryption not only applies to data being stored but also to the snapshots and backups of the EBS volumes, ensuring persistent security across various states of data. By using EBS encryption, organizations can comply with regulatory requirements and safeguard their data with minimal effort while benefiting from the reliable performance of AWS storage solutions.

In contrast, options relating to I/O performance enhancement, magnetic storage types, or backup processes do not accurately capture the core function or purpose of EBS encryption, which uniquely focuses on safeguarding data through encryption.
