Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 198 discussion

If you see MongoDB, just go ahead and look for the answer that says DocumentDB.

Option D is the correct solution that meets all the requirements: º Use Amazon Elastic Kubernetes Service (Amazon EKS) with AWS Fargate for compute and Amazon DocumentDB (with MongoDB compatibility) for data storage. The key reasons are: º EKS allows running the Kubernetes environment on AWS without changes. º Using Fargate removes the need to provision and manage EC2 instances. º DocumentDB provides MongoDB compatibility so the data layer is unchanged.

Applications are already containerized. Amazon EKS is fully managed kubernetes service. FarGate = Less overhead of managing infrastructure. Amazon DocumentDB is MongoDB Compatible. Answer D

no brainer says D

Question keyword "containerized application", "Kubernetes cluster", "no changes or deployment method changes". Choose C, not D. But "minimizes operational overhead", choose D.

This solution allows the company to leverage EKS to manage the K8s cluster and Fargate to handle the compute resources without requiring manual management of EC2 worker nodes. The use of DocumentDB provides a fully managed MongoDB-compatible database service in AWS. A. would require managing and scaling the EC2 instances manually, which increases operational overhead. B. would require significant changes to the application code as DynamoDB is a NoSQL database with a different data model compared to MongoDB. C. would also require code changes to adapt to DynamoDB's different data model, and managing EC2 worker nodes increases operational overhead.

The solution meets these requirements is option D.

minimizes operational overhead = Serverless (Fargate) MongoDB = DocumentDB

To minimize operational overhead and avoid making any code or deployment method changes, the company can use Amazon Elastic Kubernetes Service (EKS) with AWS Fargate for computing and Amazon DocumentDB (with MongoDB compatibility) for data storage. This solution allows the company to run the containerized application on EKS without having to manage the underlying infrastructure or make any changes to the application code. AWS Fargate is a fully-managed container execution environment that allows you to run containerized applications without the need to manage the underlying EC2 instances. Amazon DocumentDB is a fully-managed document database service that supports MongoDB workloads, allowing the company to use the same database platform as in their on-premises environment without having to make any code changes.

Option D

D meets the requirements

D EKS because of Kubernetes so A and B are eliminated not C because of MongoDB and Fargate is more expensive
