SAA-C03 Question 211
Single answerA company is designing a solution to store critical financial data that must be highly durable, replicated across multiple facilities for disaster recovery, and accessible with low latency. Additionally, the company needs to ensure that the storage solution adheres to compliance requirements for data integrity audits. Which AWS storage service should they choose?
- A
Amazon S3 with Cross-Region Replication (CRR)
- B
Amazon EFS (Elastic File System)
- C
Amazon FSx for Windows File Server
- D
Amazon S3 Glacier Deep Archive
Show answer and explanation
Correct answer: A
Explanation
Amazon S3 with Cross-Region Replication (CRR) is the best choice for storing critical financial data because it provides unmatched durability (11 9s), the ability to replicate data across regions for disaster recovery, and compliance features like versioning and audit logging. Other options, such as EFS and FSx, do not meet all the requirements, while S3 Glacier Deep Archive is focused on long-term archival storage rather than low-latency access.
- A. Correct.
Amazon S3 with Cross-Region Replication (CRR) provides high durability (99.999999999% durability), replicates data across AWS Regions for disaster recovery, and supports features like versioning and audit logging for compliance, making it the ideal choice for critical financial data.
- B. Incorrect.
Amazon EFS is a shared file system designed for low-latency access but is not optimized for high durability or cross-region replication, which are key requirements in this scenario.
- C. Incorrect.
Amazon FSx for Windows File Server is a managed file storage service for Windows-based applications. While it provides low latency, it lacks native cross-region replication and the high durability guarantees required for critical financial data.
- D. Incorrect.
Amazon S3 Glacier Deep Archive is a cost-effective, long-term storage option for data that is rarely accessed. It is not suitable for low-latency access, which is required in this use case.
