As a solutions architect, how would you reduce storage costs for a company with data in Amazon S3 Standard, requiring a 25-year data retention policy and immediate access to the most recent 2 years of data?
Explanation:
The correct answer is B. Setting up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 2 years meets the requirement of having the most recent 2 years of data highly available and immediately retrievable while also significantly reducing storage costs for older data. This approach complies with the company's need to keep data for at least 25 years. Options A, C, and D do not satisfy the requirement for the most recent 2 years of data to be highly available and immediately retrievable.
