AWS Certified Solutions Architect – Professional — Question 232

A manufacturing company is growing exponentially and has secured funding to improve its IT infrastructure and ecommerce presence. The company's ecommerce platform consists of:
✑ Static assets primarily comprised of product images stored in Amazon S3.
✑ Amazon DynamoDB tables that store product information, user information, and order information.
✑ Web servers containing the application's front-end behind Elastic Load Balancers.
The company wants to set up a disaster recovery site in a separate Region.
Which combination of actions should the solutions architect take to implement the new design while meeting all the requirements? (Choose three.)

Answer options

• A. Enable Amazon Route 53 health checks to determine if the primary site is down, and route traffic to the disaster recovery site if there is an issue.
• B. Enable Amazon S3 cross-Region replication on the buckets that contain static assets.
• C. Enable multi-Region targets on the Elastic Load Balancer and target Amazon EC2 instances in both Regions.
• D. Enable DynamoDB global tables to achieve a multi-Region table replication.
• E. Enable Amazon CloudWatch and create CloudWatch alarms that route traffic to the disaster recovery site when application latency exceeds the desired threshold.
• F. Enable Amazon S3 versioning on the source and destination buckets containing static assets to ensure there is a rollback version available in the event of data corruption.

Correct answer: A, B, D

Explanation

The correct actions include enabling Amazon Route 53 health checks to manage traffic redirection, enabling Amazon S3 cross-Region replication for static assets to ensure availability, and activating DynamoDB global tables for multi-Region replication of data. The other options, while useful in different contexts, do not directly address the primary needs for disaster recovery and replication in this scenario.
