AWS Certified Solutions Architect Associate SAA-C03 Practice Question

A scientific research institute needs to offload a large collection of genomic data sets from its on-premises servers to AWS. The data sets are seldom accessed, but when they are, a delay of several hours is acceptable. The institute requires a highly cost-effective solution for storing and retrieving these data sets, with a strong focus on minimizing storage costs. What method represents the MOST cost-optimized approach to store this data?

  • Utilize the Hadoop Distributed File System (HDFS) on Amazon EMR with occasional syncing to S3 for the data sets not actively in use.

  • Implement a Storage Gateway with stored volumes to gradually move the data sets into Amazon S3 over a direct connection.

  • Store the genomic data sets using the S3 Glacier Deep Archive storage class after initial upload completion.

  • Leverage S3 Intelligent-Tiering to automatically optimize costs between frequent and infrequent access tiers for the data sets.
