Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 567 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C02
Question #: 567
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A solutions architect is migrating a document management workload to AWS. The workload keeps 7 TiB of contract documents on a shared storage file system and tracks them on an external database. Most of the documents are stored and retrieved eventually for reference in the future. The application cannot be modified during the migration, and the storage solution must be highly available.
Documents are retrieved and stored by web servers that run on Amazon EC2 instances in an Auto Scaling group. The Auto Scaling group can have up to 12 instances.
Which solution meets these requirements MOST cost-effectively?

  • A. Provision an enhanced networking optimized EC2 instance to serve as a shared NFS storage system.
  • B. Create an Amazon S3 bucket that uses the S3 Standard-Infrequent Access (S3 Standard-IA) storage class. Mount the S3 bucket to the EC2 instances in the Auto Scaling group.
  • C. Create an SFTP server endpoint by using AWS Transfer for SFTP and an Amazon S3 bucket. Configure the EC2 instances in the Auto Scaling group to connect to the SFTP server.
  • D. Create an Amazon Elastic File System (Amazon EFS) file system that uses the EFS Standard-Infrequent Access (EFS Standard-IA) storage class. Mount the file system to the EC2 instances in the Auto Scaling group.

Document management Many reporting systems for business applications rely on accessible shared file storage in support of business functions. With EFS Standard-IA and EFS One Zone-IA storage classes, you can easily and cost-effectively store and access files from shared file systems, eliminating the need to manage data to control costs. If reports are accessed later, EFS Intelligent-Tiering can automatically move accessed reports to EFS Standard or EFS One Zone storage classes, depending on whether your file system uses Standard or One Zone storage classes. https://aws.amazon.com/efs/features/infrequent-access/

To store data to S3, you need to modify application. It is clearly mentioned that application can't be modified then option D is most appropriate.
