Answer: Create an Amazon Elastic File System (Amazon EFS) file system and a mount target for each subnet that contains nodes in the EKS cluster. Configure the ReplicaSet to mount the file system. Direct the application to store files in the file system. Configure AWS Backup to back up and retain copies of the data for 1 year.
The correct answer is A. Explanation: 1. Amazon Elastic File System (Amazon EFS) provides a scalable, fully-managed, shared file storage solution that can be mounted simultaneously across multiple Availability Zones (AZs). This feature makes it particularly suitable for applications requiring access to a common file system from multiple pods in an Amazon EKS cluster, ensuring consistency and durability of data across different nodes and AZs. 2. By creating a mount target for each subnet containing the EKS nodes, you ensure optimal network performance and availability of the file system, which is crucial for applications that generate and access many small files frequently. 3. Amazon EFS is designed to provide low-latency performance, which satisfies the requirement for the fastest storage performance. It supports highly parallel access and offers throughput and IOPS characteristics that are suitable for workloads with many small file operations. 4. AWS Backup integration with Amazon EFS allows for automated and managed backup processes. Configuring AWS Backup ensures that the files stored in EFS are backed up and retained for the required period of 1 year, thereby meeting the data retention and backup requirements effectively. In summary, Amazon EFS with AWS Backup provides a high-performance, scalable, and resilient solution that perfectly matches the requirements of the application in the scenario.

A company has an application that runs as a ReplicaSet of multiple pods in an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. The EKS cluster has nodes in multiple Availability Zones. The application generates many small files that must be accessible across all running instances of the application. The company needs to back up the files and retain the backups for 1 year. Which solution will meet these requirements while providing the FASTEST storage performance?
A
Create an Amazon Elastic File System (Amazon EFS) file system and a mount target for each subnet that contains nodes in the EKS cluster. Configure the ReplicaSet to mount the file system. Direct the application to store files in the file system. Configure AWS Backup to back up and retain copies of the data for 1 year.
B
Create an Amazon Elastic Block Store (Amazon EBS) volume. Enable the EBS Multi-Attach feature. Configure the ReplicaSet to mount the EBS volume. Direct the application to store files in the EBS volume. Configure AWS Backup to back up and retain copies of the data for 1 year.
C
Create an Amazon S3 bucket. Configure the ReplicaSet to mount the S3 bucket. Direct the application to store files in the S3 bucket. Configure S3 Versioning to retain copies of the data. Configure an S3 Lifecycle policy to delete objects after 1 year.
D
Configure the ReplicaSet to use the storage available on each of the running application pods to store the files locally. Use a third-party tool to back up the EKS cluster for 1 year.
