CLF-C02 Question #199: Real Exam Question with Answer & Explanation

Question

Which AWS solution gives companies the ability to use protocols such as NFS to store and retrieve objects in Amazon S3?

Options

• AAmazon FSx for Lustre
• BAWS Storage Gateway volume gateway
• CAWS Storage Gateway file gateway
• DAmazon Elastic File System (Amazon EFS)

Explanation

The AWS Storage Gateway file gateway enables companies to store and retrieve objects in Amazon S3 using standard file protocols like NFS and SMB. This integrates on-premises applications with cloud storage seamlessly.

Common mistakes.

• A. Amazon FSx for Lustre is a high-performance file system designed for HPC workloads, not for gateway-based access to S3 objects via NFS/SMB for general file storage.
• B. AWS Storage Gateway volume gateway provides block storage to on-premises applications that can be backed by S3, but it does not offer a file interface (NFS/SMB) for S3 objects.
• D. Amazon Elastic File System (Amazon EFS) is a fully managed NFS file system for EC2 instances and on-premises servers, but it stores data directly in EFS, not in Amazon S3.
