A global manufacturing firm runs a quality-control imaging system across several physical factories. The local factory systems require low-latency access to raw imaging data generated during the last 30 days. After 30 days, the data must be archived in the cloud, where it must remain durable and highly available for regulatory audits, with a Recovery Time Objective (RTO) of 5 hours. To protect against a regional disaster, all cloud archives must be replicated to a secondary AWS Region with a Recovery Point Objective (RPO) of 15 minutes. Which combination of actions should a solutions architect recommend to satisfy these requirements? (Select TWO.)
- Deploy an Amazon S3 File Gateway at each physical factory to provide low-latency local access to the active files while automatically uploading the data to an Amazon S3 bucket in the primary Region.Answer
- Configure Amazon S3 Cross-Region Replication (CRR) to a secondary Region with S3 Replication Time Control (RTC) enabled, and apply S3 Lifecycle rules to transition objects to Amazon S3 Glacier Flexible Retrieval after 30 days.Answer
- CConfigure Amazon S3 Cross-Region Replication (CRR) to a secondary Region with S3 Replication Time Control (RTC) enabled, and apply S3 Lifecycle rules to transition objects to Amazon S3 Glacier Deep Archive after 30 days to minimize long-term storage costs.
- DConfigure an Amazon RDS for PostgreSQL database instance for the application's metadata, and deploy an RDS Read Replica in the secondary Region to act as the primary automatic failover target in the event of a primary Region outage.
- EEstablish a Pilot Light disaster recovery strategy in the secondary Region by configuring the local quality-control application to write directly to an Amazon EFS file system configured with replication, expecting zero RTO for client failover.
Answer
Deploying an Amazon S3 File Gateway at the factories to provide local caching, and configuring Amazon S3 Cross-Region Replication with Replication Time Control enabled along with lifecycle rules to transition objects to Amazon S3 Glacier Flexible Retrieval after 30 days.
The correct options involve deploying an Amazon S3 File Gateway at the factories to provide low-latency local access to the active files while uploading data to S3, and configuring Amazon S3 Cross-Region Replication (CRR) with S3 Replication Time Control (RTC) enabled to meet the 15-minute RPO. Additionally, using S3 Lifecycle rules to transition objects to Amazon S3 Glacier Flexible Retrieval after 30 days is correct because standard retrieval takes 3-5 hours, which satisfies the 5-hour RTO limit.
Step-by-Step Solution
Key Concept
Designing hybrid cloud storage systems using Amazon S3 File Gateway for local caching, combined with cross-region replication (RTC) and S3 Glacier Flexible Retrieval to meet strict RTO and RPO objectives.
