Answer: Convert the Aurora Serverless v1 database to a standard Aurora MySQL global database covering both the primary and secondary Regions, deploy the solution in the secondary Region, and set up both Regional solutions for an active-passive operation.
The correct answer is D. Upgrading the Aurora Serverless v1 database to a standard Aurora MySQL global database which spans both the source and target Regions ensures high availability and low-latency reads globally. Additionally, deploying the solution in the target Region and configuring the two Regional solutions in an active-passive setup allows for a quick and efficient failover mechanism. This setup meets the RTO of 5 minutes and RPO of 1 minute required by the company. Option B only includes creating a runbook, which does not provide the active-passive configuration needed for quick recovery.

A company operates a SaaS solution on AWS, utilizing Amazon API Gateway for HTTPS endpoints, AWS Lambda for compute tasks, and Amazon Aurora Serverless v1 for data storage. The solution is deployed using AWS SAM and spans multiple Availability Zones without a disaster recovery plan. Given an RTO of 5 minutes and an RPO of 1 minute, what DR strategy should a solutions architect implement to ensure recovery in another AWS Region?
A
Establish a read replica of the Aurora Serverless v1 database in the secondary Region, utilize AWS SAM to script a deployment runbook for the secondary Region, and promote the read replica to primary during a disaster scenario.
B
Upgrade the Aurora Serverless v1 database to a standard Aurora MySQL global database spanning both the primary and secondary Regions, employ AWS SAM to script a deployment runbook for the secondary Region.
C
Set up an Aurora Serverless v1 DB cluster with multiple writer instances in the secondary Region, deploy the solution there, and configure both Regional solutions for an active-passive setup.
D
Convert the Aurora Serverless v1 database to a standard Aurora MySQL global database covering both the primary and secondary Regions, deploy the solution in the secondary Region, and set up both Regional solutions for an active-passive operation.
