Which solution will meet these requirements?
Set up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive immediately.
Set up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 2 years.
Use S3 Intelligent-Tiering. Activate the archiving option to ensure that data is archived in S3 Glacier Deep Archive.
Set up an S3 Lifecycle policy to transition objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) immediately and to S3 Glacier Deep Archive after 2 years.
Explanations:
Transitioning objects to S3 Glacier Deep Archive immediately does not meet the requirement for high availability and immediate retrieval for the most recent 2 years, as S3 Glacier Deep Archive is designed for long-term storage with retrieval times that can take hours.
This option allows the most recent 2 years of data to remain in S3 Standard, ensuring high availability and immediate retrieval. After 2 years, the data can transition to S3 Glacier Deep Archive for cost savings while still retaining it for the required 25 years.
While S3 Intelligent-Tiering with archiving can reduce costs over time, it doesn’t specifically meet the requirement for retaining high availability and immediate retrieval for the first 2 years since it may move objects to lower-cost storage based on access patterns. This could lead to delays in retrieval.
Transitioning to S3 One Zone-IA immediately would not ensure high availability for the first 2 years, as S3 One Zone-IA stores data in a single Availability Zone, which does not meet the requirement for data to be highly available. Transitioning to S3 Glacier Deep Archive after 2 years is correct for cost savings, but the initial step is flawed.
I evaluate that the answer is:
Set up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 2 years.
