AWS Certified Cloud Practitioner (CLF-C02) — Question 621

A company needs a managed NFS file system that the company can use with its AWS compute resources.

Which AWS service or feature will meet these requirements?

Answer options

• A. Amazon Elastic Block Store (Amazon EBS)
• B. AWS Storage Gateway Tape Gateway
• C. Amazon S3 Glacier Flexible Retrieval
• D. Amazon Elastic File System (Amazon EFS)

Correct answer: D

Explanation

Amazon Elastic File System (Amazon EFS) is a managed file storage service that supports the Network File System (NFS) protocol, allowing multiple AWS compute resources to access it simultaneously. Amazon EBS offers block-level storage for single instances, while AWS Storage Gateway Tape Gateway and Amazon S3 Glacier Flexible Retrieval are designed for backup and archival purposes rather than active NFS file sharing.
