AWS Certified Cloud Practitioner Practice Exam

The main distinction between Amazon S3 (Simple Storage Service) and Amazon EBS (Elastic Block Store) lies in their intended use cases and functionalities. Amazon S3 is designed for object storage, allowing users to store and retrieve any amount of data at any time from anywhere on the web. Its primary purpose is to store unstructured data such as documents, images, videos, and backups.

In contrast, Amazon EBS is a block storage service that is tightly integrated with Amazon EC2 (Elastic Compute Cloud) instances. EBS volumes are used to provide persistent block storage that can be attached to EC2 instances, functioning like traditional disk drives. This allows applications to read from and write to EBS volumes with low latency, similar to interacting with a hard drive.

Choosing option B highlights that S3 is geared toward storing files in an object format, while EBS is specifically designed for providing block storage volumes that can be used by EC2 instances. This distinction is crucial for understanding how each service fits into the broader AWS ecosystem and how they can be used effectively depending on the specific needs of an application or workload.
