SAP-C02 Exam - Question 405

Question

A company needs to implement a disaster recovery (DR) plan for a web application. The application runs in a single AWS Region.

The application uses microservices that run in containers. The containers are hosted on AWS Fargate in Amazon Elastic Container Service (Amazon ECS). The application has an Amazon RDS for MySQL DB instance as its data layer and uses Amazon Route 53 for DNS resolution. An Amazon CloudWatch alarm invokes an Amazon EventBridge rule if the application experiences a failure.

A solutions architect must design a DR solution to provide application recovery to a separate Region. The solution must minimize the time that is necessary to recover from a failure.

Which solution will meet these requirements?

Examice · Accepted Answer

The best solution to minimize recovery time involves setting up a second ECS cluster and ECS service on Fargate in the separate Region and using a cross-Region read replica of the RDS DB instance. In the event of a failure, the read replica can quickly be promoted to the primary database, ensuring minimal downtime. The solution should also include an AWS Lambda function to promote the read replica to the primary database and update Route 53 to route traffic to the second ECS cluster. Updating the EventBridge rule to invoke the Lambda function ensures automatic failover when a failure is detected.

Answer C. Configure RDS read-replica instead of Snapshots. Invoke Lambda function to promote read-replica to primary and update Route53 to point to secondary region incase of DR
