Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 395 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 395
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company hosts a software as a service (SaaS) solution on AWS. The solution has an Amazon API Gateway API that serves an HTTPS endpoint. The API uses AWS Lambda functions for compute. The Lambda functions store data in an Amazon Aurora Serverless v1 database.

The company used the AWS Serverless Application Model (AWS SAM) to deploy the solution. The solution extends across multiple Availability Zones and has no disaster recovery (DR) plan.

A solutions architect must design a DR strategy that can recover the solution in another AWS Region. The solution has an RTO of 5 minutes and an RPO of 1 minute.

What should the solutions architect do to meet these requirements?

  • A. Create a read replica of the Aurora Serverless v1 database in the target Region. Use AWS SAM to create a runbook to deploy the solution to the target Region. Promote the read replica to primary in case of disaster.
  • B. Change the Aurora Serverless v1 database to a standard Aurora MySQL global database that extends across the source Region and the target Region. Use AWS SAM to create a runbook to deploy the solution to the target Region.
  • C. Create an Aurora Serverless v1 DB cluster that has multiple writer instances in the target Region. Launch the solution in the target Region. Configure the two Regional solutions to work in an active-passive configuration.
  • D. Change the Aurora Serverless v1 database to a standard Aurora MySQL global database that extends across the source Region and the target Region. Launch the solution in the target Region. Configure the two Regional solutions to work in an active-passive configuration.

One thing we can learn here is if you see "aurora serverless VERSION 1" -> migrate away from this

D is the answer. Convert the Aurora Serverless v1 database to a standard Aurora MySQL global database extending across the source and target regions, launch the solution in the target region, and configure the two regional solutions to work in an active-passive configuration. This approach provides the necessary speed for recovery and data replication to meet the strict RTO and RPO. Aurora Serverless v1 doesn't support read replicas, cross region replicas, or global databases. https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-serverless.html#aurora-serverless.limitations

Why not B? Option B can fulfill the requirement for RTO of 5 mins and RPO of 1 min. Option D Active-Passive require manual intervention and introduce additional complexity.

B is indeed a better choice here because it focuses on using a global database with automated deployment, which is critical for achieving both the RTO and RPO requirements efficiently.

D. Altere o banco de dados Aurora Serverless v1 para um banco de dados global Aurora MySQL padrão que se estende pela região de origem e pela região de destino. Inicie a solução na região de destino. Configure as duas soluções regionais para funcionarem em uma configuração ativa-passiva.

Selected Answer: D
Option D (Change to Aurora MySQL Global Database and Launch Solution in Target Region with Active-Passive Configuration) is the most suitable solution. It addresses both the database replication and application layer readiness in the target region, meeting the specified RTO and RPO requirements.

D is incorrect because changing the Aurora Serverless v1 database to a standard Aurora MySQL global database that extends across the source Region and the target Region and launching the solution in the target Region does not meet the RTO and RPO requirements.

To design a disaster recovery (DR) strategy that can recover the solution in another AWS Region with an RTO of 5 minutes and an RPO of 1 minute, the best solution would be to create a read replica of the Aurora Serverless v1 database in the target Region. Then, use AWS SAM to create a runbook to deploy the solution to the target Region. Finally, promote the read replica to primary in case of disaster.
