What should a solutions architect recommend?
Use Amazon S3 with cross-Region replication enabled. After 30 days, transition the data to Amazon S3 Glacier using lifecycle policy.
Use Amazon S3 with cross-origin resource sharing (CORS) enabled. After 30 days, transition the data to Amazon S3 Glacier using a lifecycle policy.
Use Amazon S3 with cross-Region replication enabled. After 30 days, transition the data to Amazon S3 Glacier Deep Achieve using a lifecycle policy.
Use Amazon S3 with cross-origin resource sharing (CORS) enabled. After 30 days, transition the data to Amazon S3 Glacier Deep Archive using a lifecycle policy.
Explanations:
Using Amazon S3 with cross-Region replication ensures multiple copies are stored in different locations for compliance. Transitioning to S3 Glacier after 30 days is suitable for cost savings while still allowing access to records within the required SLA.
Cross-origin resource sharing (CORS) is not relevant to storing or replicating data and does not meet the requirement for compliance. Transitioning to S3 Glacier is correct, but this option fails to address the replication aspect.
While S3 with cross-Region replication is a valid approach, transitioning to S3 Glacier Deep Archive is unnecessary for records that need to be accessible within a 4-hour SLA after 30 days, as Glacier is sufficient for long-term storage.
Similar to option C, CORS is not applicable for this use case. Although transitioning to S3 Glacier Deep Archive is mentioned, it does not fulfill the SLA requirements for accessibility and retrieval of records.
I systematize that the answer is:
Use Amazon S3 with cross-Region replication enabled. After 30 days, transition the data to Amazon S3 Glacier using lifecycle policy.
