AWS Certified Solutions Architect – Professional — Question 670

A company is creating a sequel for a popular online game. A large number of users from all over the world will play the game within the first week after launch.
Currently, the game consists of the following components deployed in a single AWS Region:
✑ Amazon S3 bucket that stores game assets
✑ Amazon DynamoDB table that stores player scores
A solutions architect needs to design a multi-Region solution that will reduce latency, improve reliability, and require the least effort to implement.
What should the solutions architect do to meet these requirements?

Answer options

• A. Create an Amazon CloudFront distribution to serve assets from the S3 bucket. Configure S3 Cross-Region Replication. Create a new DynamoDB table in a new Region. Use the new table as a replica target for DynamoDB global tables.
• B. Create an Amazon CloudFront distribution to serve assets from the S3 bucket. Configure S3 Same-Region Replication. Create a new DynamoDB table in a new Region. Configure asynchronous replication between the DynamoDB tables by using AWS Database Migration Service (AWS DMS) with change data capture (CDC).
• C. Create another S3 bucket in a new Region, and configure S3 Cross-Region Replication between the buckets. Create an Amazon CloudFront distribution and configure origin failover with two origins accessing the S3 buckets in each Region. Configure DynamoDB global tables by enabling Amazon DynamoDB Streams, and add a replica table in a new Region.
• D. Create another S3 bucket in the sine Region, and configure S3 Same-Region Replication between the buckets. Create an Amazon CloudFront distribution and configure origin failover with two origins accessing the S3 buckets. Create a new DynamoDB table in a new Region. Use the new table as a replica target for DynamoDB global tables.

Correct answer: C

Explanation

To achieve high reliability and low latency across multiple regions with minimal effort, the solution must replicate both assets and data. Using S3 Cross-Region Replication (CRR) combined with Amazon CloudFront origin failover ensures that game assets remain highly available even if a primary region fails. Additionally, enabling Amazon DynamoDB Streams allows the creation of DynamoDB global tables, which provides fully managed, multi-Region, active-active database replication with minimal configuration.
