  • A. Amazon FSx Multi-AZ deployments
  • B. Amazon Elastic Block Store (Amazon EBS) Multi-Attach volumes

Selected Answer: C
The other options are incorrect for the following reasons: A. Amazon FSx Multi-AZ deployments Amazon FSx is a managed file system service that provides access to file systems that are hosted on Amazon EC2 instances. Amazon FSx does not support native protocols, such as NFS. B. Amazon Elastic Block Store (Amazon EBS) Multi-Attach volumes Amazon EBS is a block storage service that provides durable, block-level storage volumes for use with Amazon EC2 instances. Amazon EBS Multi-Attach volumes can be attached to multiple EC2 instances at the same time, but they cannot be mounted by multiple Linux instances through native protocols, such as NFS. D. Amazon Elastic File System (Amazon EFS) with a single mount target and multiple access points A single mount target can only be used to mount the file system on a single EC2 instance. Multiple access points are used to provide access to the file system from different VPCs.

"A single mount target can only be used to mount the file system on a single EC2 instance. Multiple access points are used to provide access to the file system from different VPCs." This is clearly wrong. You can have exactly one EFS mount target per subnet (AZ), and of course this mount target can be used by many clients (EC2 instances, containers etc.) - see diagram here for example: https://docs.aws.amazon.com/efs/latest/ug/accessing-fs.html In my opinion, C and D are equally valid answers.

D is not valid answer because "the solution must be highly available" then it must be multi-AZ: every AZ requires a mount target

Amazon FSx ONTAP supports clients mounting it with NFS. https://docs.aws.amazon.com/fsx/latest/ONTAPGuide/attach-linux-client.html. Though A is not clear about which FSx product is used

Selected Answer: C
Amazon EFS is a fully managed file system service that provides scalable, shared storage for Amazon EC2 instances. It supports the Network File System version 4 (NFSv4) protocol, which is a native protocol for Linux-based systems. EFS is designed to be highly available, durable, and scalable.
