SAA-C03 Exam - Question 822

Question

A company recently migrated its application to AWS. The application runs on Amazon EC2 Linux instances in an Auto Scaling group across multiple Availability Zones. The application stores data in an Amazon Elastic File System (Amazon EFS) file system that uses EFS Standard-Infrequent Access storage. The application indexes the company's files. The index is stored in an Amazon RDS database.

The company needs to optimize storage costs with some application and services changes.

Which solution will meet these requirements MOST cost-effectively?

Examice · Accepted Answer

To optimize storage costs most effectively, creating an Amazon S3 bucket that uses an Intelligent-Tiering lifecycle policy is the best solution. Intelligent-Tiering automatically moves data between two access tiers when access patterns change, which reduces costs. It is more cost-effective than continuously storing data in EFS Standard-Infrequent Access or using other options like FSx for Windows or OpenZFS, which might have higher costs or are not designed for such use cases. S3 Glacier Flexible Retrieval is a viable option for archival storage but would not be the most efficient for scenarios requiring regular access due to retrieval times and costs. Therefore, using Amazon S3 with Intelligent-Tiering optimizes storage costs while maintaining accessibility.
