SAP-C02 Question 267
Select 2A global e-commerce company is building a new data analytics platform for their customer purchase data. The platform needs to store large amounts of data with high durability and availability, support cross-region replication to ensure low-latency access for customers worldwide, and maintain data integrity. Which combination of AWS storage services and replication strategies should the company implement?
- A
Use Amazon S3 with Cross-Region Replication (CRR) to replicate objects between buckets in different AWS Regions.
- B
Use Amazon RDS with Multi-AZ deployments to synchronize data across regions.
- C
Use Amazon S3 with Same-Region Replication (SRR) to replicate objects within the same AWS Region.
- D
Use Amazon ElastiCache for Redis with Global Datastore to replicate data across multiple AWS Regions.
- E
Use Amazon S3 with Versioning enabled and replicate data using AWS DataSync for cross-region replication.
Show answer and explanation
Correct answers: A, D
Explanation
To meet the requirement for global low-latency access and data integrity, Amazon S3 with Cross-Region Replication (CRR) ensures that objects are replicated to another AWS Region. Additionally, Amazon ElastiCache for Redis with Global Datastore enables fast, low-latency access to cached data across multiple regions, complementing the analytics platform's needs. Amazon RDS Multi-AZ and S3 Same-Region Replication do not provide cross-region replication, while AWS DataSync is not designed for ongoing cross-region replication.
- A. Correct.
Amazon S3 with Cross-Region Replication (CRR) is a suitable choice for replicating objects across AWS Regions. This ensures data durability and availability across multiple regions, meeting the global access requirement.
- B. Incorrect.
Amazon RDS Multi-AZ deployments provide high availability and disaster recovery within a single region, but they do not support cross-region replication natively. This does not meet the global access requirement.
- C. Incorrect.
Amazon S3 Same-Region Replication (SRR) replicates objects within the same region, which does not fulfill the requirement for cross-region replication for low-latency global access.
- D. Correct.
Amazon ElastiCache for Redis with Global Datastore supports cross-region replication, enabling low-latency access to cached data across multiple AWS Regions. This is a suitable solution for part of the requirement.
- E. Incorrect.
Amazon S3 Versioning and AWS DataSync are useful for replication and version control, but DataSync is not designed for continuous replication and does not integrate natively with S3 for cross-region replication.
