SAP-C02 Question #633: Real Exam Question with Answer & Explanation
The correct answer is D: Deploy the application on Amazon Elastic Kubernetes Service (Amazon EKS) with AWS Fargate. To reduce operational overhead and support significant scaling for a containerized application with a Kafka dependency, the best approach is to migrate the application to Amazon EKS with AWS Fargate and the Kafka cluster to Amazon MSK Serverless.
Question
A company has application services that have been containerized and deployed on multiple Amazon EC2 instances with public IPs. An Apache Kafka cluster has been deployed to the EC2 instances. A PostgreSQL database has been migrated to Amazon RDS for PostgreSQL. The company expects a significant increase of orders on its platform when a new version of its flagship product is released. What changes to the current architecture will reduce operational overhead and support the product release?
Options
- ACreate an EC2 Auto Scaling group behind an Application Load Balancer. Create additional read
- BCreate an EC2 Auto Scaling group behind an Application Load Balancer. Deploy the DB instance
- CDeploy the application on a Kubernetes cluster created on the EC2 instances behind an
- DDeploy the application on Amazon Elastic Kubernetes Service (Amazon EKS) with AWS Fargate
Explanation
To reduce operational overhead and support significant scaling for a containerized application with a Kafka dependency, the best approach is to migrate the application to Amazon EKS with AWS Fargate and the Kafka cluster to Amazon MSK Serverless.
Common mistakes.
- A. While creating an EC2 Auto Scaling group and RDS read replicas improves scalability, it still requires managing the underlying EC2 instances for containers and the self-managed Kafka cluster, which does not significantly reduce overall operational overhead.
- B. This option has similar drawbacks to A regarding EC2 management and self-managed Kafka. Deploying the DB instance to Multi-AZ primarily provides high availability, not necessarily the read scalability for a significant increase in orders.
- C. Deploying a Kubernetes cluster on EC2 instances introduces significant operational overhead for managing the Kubernetes control plane and worker nodes, directly contradicting the requirement to reduce operational overhead for the entire architecture.
