Question 663 of 1,660
SAP-C02 Design for New Solutions Practice Question
A company is running a containerized application on Amazon ECS with Fargate launch type. The application needs to store persistent data that must be shared across multiple containers in the same task. Which storage option should the company use?
⚠ Common exam trap
Many exam-takers confuse Amazon EBS with a shared storage solution, but EBS volumes are zonal and single-instance attachable, making them incompatible with multi-container sharing in Fargate, whereas EFS is the only AWS-native, shared, persistent file system that works seamlessly with Fargate.

Correct answer & explanation
✓
Amazon EFS file system
Amazon EFS provides a shared, persistent, and scalable NFS file system that can be mounted concurrently by multiple containers within the same ECS task using Fargate. EFS supports the NFSv4.1 protocol, enabling simultaneous read/write access from multiple containers, which meets the requirement for shared persistent storage across containers in the same task.
