When an administrator is looking to deploy shared file access Linux-based workloads which will require up to petabytes of data stores, what is the best-suited file storage option to use?

Answer options:

A.Amazon EFS
B.Amazon S3
C.AWS Snowball
D.Amazon EBS

Correct Answer – A
Amazon Elastic File Storage (EFS) is the best-suited file storage option for the described scenario. It is designed for shared file access and scaling to petabyte data store.

Option B is incorrect because Amazon S3 is an object data store which is not suitable for deploying Linux-based workloads as the scenario outlines.
Option C is incorrect because AWS Snowball is a data transport solution and data migration which is not suitable for deploying shared file access builds.

Option D is incorrect because Amazon Elastic Block Store is block storage service for access by an EC2 instance but without the capability of a share file access. Applications that utilize persistent or dedicated block storage for a single instance can use Amazon EBS storage.
