Question 1,107 of 1,660
SAP-C02 Design for New Solutions Practice Question
A company is designing a new application that will run on Amazon ECS with Fargate. The application must be able to read and write files to a shared file system that is accessible from multiple tasks simultaneously. The file system must be durable and support NFS protocol. Which storage solution should be used?
⚠ Common exam trap
Test-takers frequently confuse Amazon EBS Multi-Attach with a shared file system, but EBS Multi-Attach is block-level storage limited to a single AZ and incompatible with Fargate, whereas EFS is a fully managed NFS file system designed for multi-task, multi-AZ access.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon EFS
Amazon EFS is the correct choice because it provides a fully managed, durable, NFS-based (Network File System) shared file system that can be mounted concurrently by multiple Amazon ECS tasks running on Fargate. EFS supports the NFSv4.1 and NFSv4.0 protocols, ensuring simultaneous read/write access across tasks, and its data is replicated across multiple Availability Zones for durability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon EBS with Multi-Attach
Why it's wrong here
Amazon EBS Multi-Attach is limited to a few instances in the same AZ and does not support NFS. It is not suitable for shared file systems across tasks.
- ✓
Amazon EFS
Why this is correct
Amazon EFS is a fully managed NFS file system that can be mounted by multiple ECS tasks across multiple AZs, providing a shared file system.
- ✗
Amazon S3
Why it's wrong here
Amazon S3 is an object store, not a file system. It does not support NFS protocol or concurrent file-level locking.
- ✗
Amazon FSx for Lustre
Why it's wrong here
Amazon FSx for Lustre is designed for high-performance computing workloads, not for general-purpose file sharing. It is not the best fit for this use case.
