AWS Certified Solutions Architect Associate SAA-C03 Practice Question

Amazon Elastic Block Store (EBS) provides block-level storage volumes that are ideal for use with EC2 instances. EBS volumes offer consistent low-latency performance required for high-performance database applications and persist independently from the lifecycle of the instances. They support point-in-time snapshots, which are essential for backups and disaster recovery.

Amazon Elastic File System (EFS) offers file-level storage accessed over a network file system, which may introduce higher latency compared to directly attached block storage, making it less suitable for high-performance databases.

Amazon Simple Storage Service (S3) is an object storage service designed for scalability and data durability but does not support block-level access or the required low-latency performance for database storage.

Amazon DynamoDB is a fully managed NoSQL database service and not a storage solution that can be attached to EC2 instances for running a database application.
