Correct answer: Amazon Elastic File System (Amazon EFS).
Why this is the answer
Amazon EFS is a fully managed, scalable, cloud-native NFS (Network File System) file system. It allows multiple EC2 instances and other AWS compute resources to access shared file storage concurrently, making it ideal for use cases like web serving, content management, and analytics. Amazon EBS provides block-level storage volumes for use with EC2 instances, not a shared NFS file system. AWS Storage Gateway (Tape Gateway) connects on-premises applications to AWS cloud storage for backup and archiving, it's not a direct NFS file system for AWS compute. Amazon S3 Glacier Flexible Retrieval is an archival storage service for infrequent data access, not a performance-oriented NFS file system.
