AWS Certified Solutions Architect Associate SAA-C03 Practice Question

Amazon Elastic File System (Amazon EFS) is the most appropriate storage service for this scenario. EFS provides a scalable, fully managed Network File System (NFS) for use with AWS Cloud services and on-premises resources. It supports standard file system semantics such as file locking and hierarchical directories, which are essential for applications that require shared file storage. EFS is designed for low-latency access to data and scales automatically as files are added and removed, making it both scalable and cost-effective. Amazon Simple Storage Service (Amazon S3) is object storage and does not support file system semantics like file locking or hierarchical directories. Amazon Elastic Block Store (Amazon EBS) provides block storage for EC2 instances and does not offer shared storage across multiple instances unless using EBS Multi-Attach, which has limitations and may not suit shared file system needs. Amazon S3 Glacier is intended for archival storage and is not suitable for frequently accessed data requiring low-latency access.
