SAP-C02 Question 268
Select 3A financial services company is required to maintain near-real-time replication of their data across two AWS Regions to support disaster recovery and compliance requirements. The data is stored in Amazon S3, Amazon RDS, and Amazon ElastiCache. Which combination of strategies will meet the requirements?
- A
Use Amazon S3 Cross-Region Replication (CRR) to replicate objects to the target region.
- B
Enable Amazon RDS Read Replicas in the target region.
- C
Use Amazon ElastiCache Global Datastore for cross-region replication.
- D
Enable Amazon S3 Transfer Acceleration for faster object uploads.
- E
Use AWS Backup to replicate snapshots of all services to the target region.
Show answer and explanation
Correct answers: A, B, C
Explanation
To satisfy the near-real-time replication requirement across AWS Regions, you need to use services and features that provide continuous or near-continuous data synchronization. Amazon S3 Cross-Region Replication handles S3 object replication, Amazon RDS Read Replicas help replicate relational databases across regions, and Amazon ElastiCache Global Datastore supports cross-region replication for caching data. AWS Backup and S3 Transfer Acceleration do not provide near-real-time replication capabilities and are unsuitable for this use case.
- A. Correct.
Amazon S3 Cross-Region Replication (CRR) is designed for replicating objects in near-real-time between two AWS Regions, fulfilling the requirements for S3.
- B. Correct.
Amazon RDS Read Replicas in another region can provide near-real-time replication for disaster recovery purposes, meeting the requirements for RDS.
- C. Correct.
Amazon ElastiCache Global Datastore supports cross-region replication, enabling near-real-time data synchronization between ElastiCache clusters in different regions.
- D. Incorrect.
Amazon S3 Transfer Acceleration improves upload speeds but does not replicate data across regions, so it does not meet the requirements for cross-region replication.
- E. Incorrect.
AWS Backup primarily focuses on creating snapshots and backups, not on near-real-time replication. While it can help with disaster recovery, it does not meet the requirement for near-real-time replication.
