A legacy application needs a proprietary file system. Which of the following can be used to store data accessible by an EC2 instance?

A	AWS EFS
B	AWS S3
C	AWS Glacier
D	AWS CloudFront

Explanation:

Detailed explanation-1: -EFS provides a file system interface, file system access semantics (such as strong consistency and file locking), and concurrently accessible storage for up to thousands of EC2 instances. Amazon EBS is a block-level storage service for use with EC2.

Detailed explanation-2: -On Windows systems, NFTS supports EFS. NTFS itself is a built-in system used to store and retrieve files. The ultimate aim of EFS is to encrypt files on hard drives from unauthorized intruders who get access to authorized users’ physical software.

Detailed explanation-3: -Amazon EFS is not supported on Windows instances. To use Amazon EFS with a Linux instance, see Amazon Elastic File System (Amazon EFS) in the Amazon EC2 User Guide for Linux Instances. To use the Amazon Web Services Documentation, Javascript must be enabled.
