DEA-C01 Question 249

Single answer

You are designing a data storage solution for a financial institution that requires extremely high resiliency and availability for their transactional data. The solution must provide multi-region redundancy and automatic failover capabilities in case of a regional outage. Which AWS service and configuration would best meet these requirements?

  1. A

    Amazon S3 with Cross-Region Replication

  2. B

    Amazon RDS with Multi-AZ Deployment

  3. C

    Amazon DynamoDB with Global Tables

  4. D

    Amazon EBS with Snapshots

Show answer and explanation

Correct answer: C

Explanation

Amazon DynamoDB with Global Tables is designed for applications that require high resiliency and availability across multiple regions. It provides automatic multi-region replication and failover, ensuring that transactional data remains available even in the event of a regional outage. This makes it the most suitable solution for the financial institution's requirements.

  • A. Incorrect.

    Amazon S3 with Cross-Region Replication provides data redundancy across regions but does not offer automatic failover capabilities, making it unsuitable for high-availability transactional data.

  • B. Incorrect.

    Amazon RDS with Multi-AZ Deployment offers high availability within a region but does not provide multi-region redundancy, which is required in this scenario.

  • C. Correct.

    Amazon DynamoDB with Global Tables provides multi-region redundancy, automatic failover, and high availability, making it the best choice for resilient and highly available transactional data.

  • D. Incorrect.

    Amazon EBS with Snapshots is a backup solution and does not offer the real-time multi-region redundancy or automatic failover needed for high-availability transactional data.
