Topic 1 Question 296
A company implements a containerized application by using Amazon Elastic Container Service (Amazon ECS) and Amazon API Gateway The application data is stored in Amazon Aurora databases and Amazon DynamoDB databases. The company automates infrastructure provisioning by using AWS CloudFormation. The company automates application deployment by using AWS CodePipeline.
A solutions architect needs to implement a disaster recovery (DR) strategy that meets an RPO of 2 hours and an RTO of 4 hours.
Which solution will meet these requirements MOST cost-effectively?
Set up an Aurora global database and DynamoDB global tables to replicate the databases to a secondary AWS Region. In the primary Region and in the secondary Region, configure an API Gateway API with a Regional endpoint. Implement Amazon CloudFront with origin failover to route traffic to the secondary Region during a DR scenario.
Use AWS Database Migration Service (AWS DMS), Amazon EventBridge, and AWS Lambda to replicate the Aurora databases to a secondary AWS Region. Use DynamoDB Streams, EventBridge. and Lambda to replicate the DynamoDB databases to the secondary Region. In the primary Region and in the secondary Region, configure an API Gateway API with a Regional endpoint. Implement Amazon Route 53 failover routing to switch traffic from the primary Region to the secondary Region.
Use AWS Backup to create backups of the Aurora databases and the DynamoDB databases in a secondary AWS Region. In the primary Region and in the secondary Region, configure an API Gateway API with a Regional endpoint. Implement Amazon Route 53 failover routing to switch traffic from the primary Region to the secondary Region.

I think the key here is to focus on the requirements. It is clearly stated that the requirement is that the strategy meet an RPO of 2 hours and an RTO of 4 hours. Even though option C is the most cost-effective, it is contingent on a few external factors, like the size of the data, the data change rate, etc., which cannot be assumed at the risk of breaching RPO and RTO requirements. So based on that, the most effective option is D.

Answer: C Weird question. Sometimes I think there is no BEST answer and that they were created just to confuse people. Anyway, thinking on cost and the mentioned RPO and RTO, I would still go with C (if they were longer, it would be easier to choose among the questions).
