Question

A company is deploying a new machine learning (ML) model in a production environment. The company is concerned that the ML model will drift over time, so the company creates a script to aggregate all inputs and predictions into a single file at the end of each day. The company stores the file as an object in an Amazon S3 bucket. The total size of the daily file is 100 GB. The daily file size will increase over time. Four times a year, the company samples the data from the previous 90 days to check the ML model for drift. After the 90-day period, the company must keep the files for compliance reasons. The company needs to use S3 storage classes to minimize costs. The company wants to maintain the same storage durability of the data. Which solution will meet these requirements?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Store the daily objects in the S3 Standard-InfrequentAccess (S3 Standard-IA) storage class. Configure an S3 Lifecycle rule to move the objects to S3 Glacier Deep Archive after 90 days. S3 Glacier Deep Archive is the lowest-cost storage for long-term archival with retrieval in hours. Amazon S3 Glacier offers low-cost archival storage for infrequently accessed data. S3 Standard-IA reduces cost for infrequently accessed data that still needs high availability. This option delivers the requirement at the lowest cost.
