Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 475
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company is designing a containerized application that will use Amazon Elastic Container Service (Amazon ECS). The application needs to access a shared file system that is highly durable and can recover data to another AWS Region with a recovery point objective (RPO) of 8 hours. The file system needs to provide a mount target m each Availability Zone within a Region.

A solutions architect wants to use AWS Backup to manage the replication to another Region.

Which solution will meet these requirements?

  • A. Amazon FSx for Windows File Server with a Multi-AZ deployment
  • B. Amazon FSx for NetApp ONTAP with a Multi-AZ deployment
  • C. Amazon Elastic File System (Amazon EFS) with the Standard storage class
  • D. Amazon FSx for OpenZFS

https://aws.amazon.com/efs/faq/ Q: What is Amazon EFS Replication? EFS Replication can replicate your file system data to another Region or within the same Region without requiring additional infrastructure or a custom process. Amazon EFS Replication automatically and transparently replicates your data to a second file system in a Region or AZ of your choice. You can use the Amazon EFS console, AWS CLI, and APIs to activate replication on an existing file system. EFS Replication is continual and provides a recovery point objective (RPO) and a recovery time objective (RTO) of minutes, helping you meet your compliance and business continuity goals.

The key thing to notice here in the question is "with a recovery point objective (RPO) of 8 hours", as it is 8 hours of time it recovery can be easily managed by EFS, no need to go for costlier and not built for this use-case(share file system) options like NetApp ONTAP(proprietary data cluster), OpenZFS(not a built in filesystem in AWS) or FSx for windows(file system for windows compatible workloads)

A: ECS is not Windows File Server so won't work B: ONTAP is proprietary data cluster completely unrelated to this question D: OpenZFS needs a Linux kind of host for access. Not a built-in filesystem in AWS by default

"The file systemhttps://www.examtopics.com/exams/amazon/aws-certified-solutions-architect-associate-saa-c03/view/48/# needs to provide a mount target in each (!) Availability Zone within a Region", most regions have three AZs, but FSx Multi-AZ provides only nodes "spread across two AZs". While "or Amazon EFS file systems that use Regional storage classes [such as Standard], you can create a mount target in each Availability Zone in an AWS Region."

Huh, comment has been scrambled a bit. Anyway FSx Multi-AZ: Mount targets in two AZs EFS Standard: Can create mount target in each AZ

In the absence of this information, we can only make an assumption based on the provided requirements. The requirement for a shared file system that can recover data to another AWS Region with a recovery point objective (RPO) of 8 hours, and the need for a mount target in each Availability Zone within a Region, are all natively supported by Amazon EFS with the Standard storage class. While Amazon FSx for NetApp ONTAP does provide shared file systems and supports both Windows and Linux, it does not natively support replication to another region through AWS Backup.

B or C, but since question didn't mention operating system type, I guess we should go with B because it is more versatile (EFS supports Linux only), although ECS containers do support windows instances...

Both B and C are feasible. Amazon FSx for NetApp ONTAP is just way overpriced for a backup storage solution. The keyword to look out for is sub milli seconds latency In real life env, Amazon Elastic File System (Amazon EFS) with the Standard storage class is good enough.

https://aws.amazon.com/efs/faq/ During a disaster or fault within an AZ affecting all copies of your data, you might experience loss of data that has not been replicated using Amazon EFS Replication. EFS Replication is designed to meet a recovery point objective (RPO) and recovery time objective (RTO) of minutes. You can use AWS Backup to store additional copies of your file system data and restore them to a new file system in an AZ or Region of your choice. Amazon EFS file system backup data created and managed by AWS Backup is replicated to three AZs and is designed for 99.999999999% (11 nines) durability.

Amazon EFS is a scalable and durable elastic file system that can be used with Amazon ECS. However, it does not support replication to another AWS Region.

To use EFS replication in a Region that is disabled by default, you must first opt in to the Region, so it does support.
