Question #1166

A media company needs to retain high-resolution video files for archival purposes for 15 years. Videos from the past year are accessed frequently for editing, but videos older than 1 year are rarely accessed. The company generates over 50 TB of video data monthly.

Which storage option meets these requirements MOST cost-effectively?

A

Store the videos in Amazon S3. Use AWS Backup to move videos more than 1 year old to S3 Glacier Deep Archive.

B

Store the videos in Amazon S3. Use S3 Lifecycle policies to move videos more than 1 year old to S3 Glacier Deep Archive.

C

Store the videos in Amazon EFS. Use AWS Backup to move videos more than 1 year old to S3 Glacier Deep Archive.

D

Store the videos in Amazon EFS. Use S3 Lifecycle policies to move videos more than 1 year old to S3 Glacier Deep Archive.

Explanation

The correct answer is B. Amazon S3 is ideal for storing large volumes of data (50 TB/month) and supports S3 Lifecycle policies to automatically transition objects to cheaper storage classes like S3 Glacier Deep Archive after 1 year. This minimizes costs while meeting retention requirements. Options A and C incorrectly use AWS Backup, which is designed for backup/restore workflows, not storage tier transitions. Options C and D use Amazon EFS, which is more expensive than S3 for large-scale storage and does not natively integrate with S3 Glacier. Key points: S3 is cost-effective for bulk storage; Lifecycle policies automate archival; Glacier Deep Archive is optimal for rarely accessed, long-term data.

Answer

The correct answer is: B
