Question
A company has a platform that contains an Amazon S3 bucket for user content. The S3 bucket has thousands of terabytes of objects, all in the S3 Standard storage class. The company has an RTO of 6 hours. The company must replicate the data from its primary AWS Region to a replication S3 bucket in another Region. The user content S3 bucket contains user-uploaded files such as videos and photos. The user content S3 bucket has an unpredictable access pattern. The number of users is increasing quickly, and the company wants to create an S3 Lifecycle policy to reduce storage costs. Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)
Options
- AMove the objects in the user content S3 bucket to S3 Intelligent-Tiering immediately
- BMove the objects in the user content S3 bucket to S3 Intelligent-Tiering after 30 days
- CMove the objects in the replication S3 bucket to S3 Standard-Infrequent Access (S3 Standard-IA)
- DMove the objects in the replication S3 bucket to S3 One Zone-Infrequent Access (S3 One Zone-
- EMove the objects in the replication S3 bucket to S3 Standard-infrequent Access (S3 Standard-IA)

Why each option
To cost-effectively manage a large S3 bucket with unpredictable access and replicate it for disaster recovery, use S3 Intelligent-Tiering for the primary bucket and S3 One Zone-IA for the replication bucket after 30 days.
S3 Intelligent-Tiering immediately optimizes costs for the primary bucket's unpredictable access patterns by automatically moving objects between frequent and infrequent access tiers without performance impact or retrieval fees.
Waiting 30 days to move objects to S3 Intelligent-Tiering (instead of immediately) results in higher S3 Standard costs for the interim period, making it less cost-effective.
S3 Standard-IA is more expensive than S3 One Zone-IA; for a replication bucket with a 6-hour RTO, One Zone-IA is more cost-effective if the single AZ durability is acceptable.
S3 One Zone-IA provides a significantly lower cost for the replication bucket after 30 days, as it stores data in a single Availability Zone, which is acceptable for disaster recovery if the 6-hour RTO can still be met by re-replication or specific recovery procedures.
Moving objects to S3 Standard-IA immediately is less cost-effective than using S3 One Zone-IA for the replication bucket, which offers lower prices for single AZ durability.
